Description

PROCESS FORPREPARING CQLD FUSION CONCRETE AND CEMENT COMPOSITIONS FROM METAL MINING AND PRODUCTION WASTE

TECHNICAL FIELD

This invention relates to processing mining waste to préparé cold fusion concrète and cernent compositions with and without métal carbonates.

BACKGROUND

Mining operations create waste products (mining residue) containing métal oxides, hydroxides, carbonates, sulfites, sulfates, sulfides, and other solid and liquid Chemicals. For example, the Bayer process of extracting alumina from bauxite minerai formulations créâtes substantial amounts of potentially hazardous bauxite residue containing sodium hydroxide, ferrons oxide, Silicon dioxide, aluminum oxide, calcium hydroxide, titanium, and other trace materials, and is sometimes radioactive. The extraction of one ton of alumina créâtes from one to two tons of bauxite residue. The bauxite residue accumulâtes in unused stockpiles for générations. Moreover, because the majority of residue impoundments are not necessarily located near the bauxite source, many different bauxite source residues can exist in a single impoundment with somewhat variable characteristics.

Lithium, which is primarily processed for use in batteries, is mined in open pits as a carbonate, but brine mining and processing is also commonly used. The byproducts of lithium processing and mining include various sulfites, sulfates, carbonates, oxides, and hydroxides. The waste from brine mining typically produces two separate materials comprising metals hydroxides and oxides on one side, and sulfites on the other. The métal hydroxides and oxides consist of manganèse, ferrous, magnésium, and other minor materials. The sulfites consist primarily of zinc, but also lithium and other metals.

Copper, gold, silver, uranium, coal, and many other materials that are mined and processed produce tailings or other waste that requires permanent storage. Many of these materials contain hazardous Chemicals, heavy metals, or high or low pH materials. Ail of these materials contain significant amounts of SiO₂.

SUMMARY

The inventor has discovered a process for preparing cold fusion concrète and cernent using mining waste. In addition to converting potentially hazardous mining waste into a useful material, the method can, in some embodiments, perform the function of carbon séquestration by converting carbon dioxide into métal carbonates.

For example, in some embodiments, the dissociating agent is an acid selected from the group consisting of oxalic acid, hydrochloric acid, carbonic acid, nitric acid, phosphoric acid, acetic acid, and combinations thereof.

In some embodiments, the method includes pre-treating the mining waste with from 5 to 35% by weight of a pH adjusting agent before addition of the carbon dioxide source such that the pH of the mining waste is between 8 and 14. The pH adjusting agent may be applied before the dissociating agent in some embodiments. The pH adjusting agent may be selected from the group consisting of alkali métal hydroxides, alkali métal metasilicates, Red Mud, and combinations thereof.

In some embodiments, the method includes comprising curing the composition by exposing the composition to ambient conditions, a direct current electrical charge, an altemating current charge, ultraviolet light, a température ranging fromlOO°F to 160°F, or combination thereof until desired strength is achieved.

In some embodiments, the method includes adding from 20 to 60% by weight aggregates to the composition. The aggregates may be naturally occurring or synthetic aggregates. In some embodiments, the aggregates are produced by separating a cold fusion concrète composition into size fractions ranging from 200 um to 50 mm and curing the size fractions.

In a second aspect, there is disclosed a method of producing a cold fusion cernent composition comprising combining:

(a) from 20 to 70% by weight of mining waste;

(d) from 20 to 70% by weight of an agent selected from the group consisting of granulated ground blast fumace slag, fly ash, synthetic or natural pozzolan that contains about 1 to 60% by weight of calcium hydroxide, and combinations thereof;

B. General Description

The inventor has discovered that hydroxides and silicates in mining waste are bénéficiai when combined with cold fusion concrète and cernent technology. This was discovered while developing cold fusion concrète materials using red mud, which is the residue from the Bayer process of extracting alumina from the bauxite minerai. The process is generally described in the flow chart presented in Fig. 1.

As discussed in the Background, the Bayer process leaves a sodium hydroxide rich waste. The sodium hydroxide rich waste is deposited in large impoundments where the Silicon dioxide concentrations in the bauxite are digested into the sodium hydroxide, leaving a variable molar concentration and combination of sodium silicate and sodium hydroxide, along with other associated and disassociated métal materials.

Similarly, the sodium hydroxide used in the Bayer process is reused several times prior to refreshment, or replacement with new sodium hydroxide. After initial use, the sodium hydroxide is then referred to as “liquor” by the Alumina Industry, as it is defined by many other industries like the paper industry. As the liquor is reused, it increases in Silicon dioxide content until the Silicon dioxide and other material content is so great that the liquor must be refreshed or disposed of due to its inability to digest the alumina in the bauxite minerai efïiciently.

The liquor is a significant portion of the red mud. Due to the elevated Silicon dioxide content in the liquor, the liquor itself is a viable candidate for use in cold fusion concrète, with or without the red mud solids, as an elevated pH material that further digests additional Silicon dioxide from pozzolans, reacts with the calcium hydroxide portions of pozzolans to create calcium silicate hydrate (CSH)/calcium silicate aluminum hydrate (CSAH), and, reacts with other cold fusion concrète ingrédients to achieve compressive strength in excess of3,000 pounds per square inch (psi) strength with low to negligible volume change and a controlled set time. The combination of liquor, with or without red mud, can produce a concrète material of high strength, extremely low permeability, and extremely high résistance to climatic variances and Chemical exposure due to the high Silicon dioxide content.

As discussed in the Background, the byproducts of lithium processing and mining include varions sulfites, sulfates, silicates, carbonates, and hydroxides including zinc, ferrous, manganèse, sodium, calcium, and magnésium. The byproducts are typically separated into two sides consisting of the hydroxide side and the sulfite/sulfate side. The inventer has discovered that, using cold fusion concrète technology, the hydroxide side of the lithium waste can be sequestered together with carbon dioxide, thereby producing métal carbonates, and the sulfide side of lithium waste can be treated with hydroxides, thereby converting the sulfide to a reacted zinc carbonate with the release and capture of hydrogen. The reacted carbonate can be used in cold fusion concrète as a filler and zinc oxide barrier (galvanized métal), and the hydrogen can be captured for use in hydrogen fueled power génération or other processes. The process is generally described in the flow chart presented in Fig. 3.

In addition to lithium, waste materials from gold, silver, copper, titanium, magnésium, and other metals, as discussed in the Background, collect in impoundments and piles, and are referred to as tailings. Métal mine tailings contain elevated Silicon dioxide contents along with hydroxides, sulfites, sulfides, sulfates, oxides, chlorides, and other materials that are either bénéficiai or not detrimental to cold fusion concrète. Many of these wastes contain undesirable materials like heavy metals, arsenic, and other materials that leach into waters unless permanently confined within a concrète mass like cold fusion concrète. The process for incorporating mine tailings in cold fusion concrète is generally described in the flow chart presented in Fig. 2.

Coal is used for heating and power génération, but unused tailings are a significant problem in the U.S. and abroad. Coal tailings are the lower carbon content coal and overburden that cannot be efïïciently bumed in power plants. Coal tailings contain calcium, ferrous oxide, aluminum, Silicon dioxide, carbon, and various other materials. Carbon dioxide is introduced into coal tailings following drying and crushing, therein sequestering carbon dioxide in the hydroxide components thereby converting into carbonates. The sequestered tailings can then be utilized in cold fusion concrète as a portion of the cementitious materials, or the sequestered tailings can be used as a permanent storage device for carbon dioxide, as a réclamation device for coal mining, as soil fill materials, or mixed with cold fusion concrète to produce aggregates.

C. Préparation of métal carbonates.

Métal carbonates can be produced for use, e.g., as a carbon dioxide sequestered landfill, aggregates for road/highway/airport base course, aggregates for bituminous pavement, aggregates for concrète, or a simple permanent storage mechanism for carbon dioxide.

The préparation of métal carbonates may occur in alkali metals, alkaline earth metals, transition metals, or other metals. Preparing alkaline earth métal or alkali métal carbonates is typically the most convenient source of producing métal carbonates, and many times consists of reducing the particle size of the métal to about a maximum of 20 microns and exposing the métal to water and carbon dioxide. The water is utilized to allow oxides that contain a single alkaline earth/alkali métal atom and one oxygen atom to retain a hydrogen atom, allowing the now hydroxide to react with carbon dioxide and form carbonates. The water also acts as a lubricant and confinement to receive carbon dioxide and thoroughly incorporate and distribute the carbon dioxide and hydroxides for thorough incorporation and transition. Another simplistic method to produce métal carbonates is to expose the métal oxide/hydroxide to hydrogen peroxide to partially or fiilly disassociate the oxide first, then introduce carbon dioxide. Testing may be performed with each oxide/hydroxide to détermine the best carbonate development method and verified by XRD, XRF, or other appropriate analytical procedure.

Most typically, transition metals and other metals must be disassociated prior to exposure to carbon dioxide. For example, the optimal dissolution of the iron oxides is achieved at a low pH, by using oxalic, hydrochloric, carbonic, or other acid that will act as a reducing agent by donating its élections to form Fe⁺³ ions; the time of mellowing the oxide in a low pH environment is determined from the acid utilized and can vary from about 2 to 48 hours. These available iron ions will then bond with the oxidized oxalates to form iron oxalates [Fe(C₂04)₂]“. Once these iron oxalates are formed, the pH level must then be adjusted to an elevated pH prior to adding hydrogen peroxide by adding either metasilicate, Red Mud, or hydroxides. This will allow the hydrogen peroxide to act as a reducing agent to reduce the Fe⁺³ ions into Fe⁺², making the iron ions compatible to bond with the carbonates (CO3 ²). The carbonates are then created by injecting carbon dioxide using a cellular bubble, liquid carbon dioxide, or carbon dioxide gas.

In the event that carbon dioxide is delivered using carbonic acid, carbon dioxide will be added to water form carbonic acid and then added to the disassociated mixture above. Since this weak acid will be added to a basic solution, it will deprotonate its protons to form carbonates. ·

Dissolving Iron oxide with oxalic acid:

Fe₂0₃ + 4C₂O$~ + 6H⁺ -» 2[Fe(C₂0₄)₂]- + 3H₂O

Additional comments: dissolving iron oxide with oxalic acid at an elevated température (100 degrees Celsius) will expedite this process.

If a different acid is introduced in-place of oxalic acid, the Chemical formulas that will change are the acid and the conjugate base of the acid.

Reacting hydrogen peroxide with iron ions in a basic solution:

2Fe³⁺ + H2O2 + 2OH~-^ 2Fe²⁺ + O2 + 2H₂O

Additional comments: hydrogen peroxide can act either as an oxidizing or reducing agent (dépendent on the pH). In order to hâve it act as a reducing agent, it must be added at an elevated pH.

Forming carbonates:

co₂ + h₂o -» h₂co₃

H₂CO₃ + OH~ -» HC0₃~

HC0₃~+ OH~^ CO₃ ²

Iron ions bonding with carbonates to form iron carbonates:

Fe²⁺ + COj~ -» FeCO₃

Once the carbonates are formed, they may be used as a landfill or incorporated into varions construction materials as indicated previously.

D. Préparation of Cold Fusion Concrète

Cold fusion concrète is a Silicon dioxide primary chemistry relying upon the glassy components of directly installed Silicon dioxide (metasilicate, that during the exothermic reaction phase with water, digests, and bonds with S1O2 pozzolans), varions minerais, and mine waste materials to achieve an approximate 70% S1O2 content, which is extremely similar to glass chemistry. The Silicon dioxide, aluminum, varions hydroxides and oxides, and calcium constituents in bauxite, lithium, gold, copper, silver, or other mining waste from either primary or majority constituents of the cold fusion concrète. As such, synergy between cold fusion concrète and mining waste exists. The ferrons and other métal components of the waste présent no deleterious reactions in the final product and heavy metals can be encapsulated safely within the glass matrix.

Cold fusion concrète can be produced from mining waste by combining variable concentrations of the following materials such that specified strength, set time, permeability, volume stability, Chemical résistance, and climate variance résistance is achieved:

about 20 to 70% by weight of the mining waste. The waste may be raw, or that which has been fully or partially processed into carbonates;

about 5 to 30% by weight of an alkali metasilicate or metasilicate pentahydrate (e.g., sodium metasilicate, calcium metasilicate, or potassium metasilicate);

about 5 to 15% by weight of a set time retarder, e.g., sodium tetraborate, boric acid, citric acid, or combination thereof;

about 20 to 70% by weight of granulated ground blast fumace slag, fly ash, or other synthetic or natural pozzolan that contains about 1 to 60% by weight of calcium hydroxide;

about 0.01 to 2% by weight of sodium caseinate, calcium caseinate, or other protein (natural or synthetic) that aids in the formation of covalent bonds;

about 0.01 to 2% by weight of an oxide or hydroxide (e.g., magnésium, calcium, potassium, lithium, aluminum) or sulfate (e.g., calcium, magnésium, potassium, lithium) that arrests plastic, drying, and autogenous shrinkage in the mixture, thereby reducing volume change; and a sufficient amount of water, if necessary, to produce a pourable consistency.

The concrète mixture may be cured normally in ambient conditions, cured with beat, or cured by electrical treatment.

Using zeolites, diatomite, polyvinyl alcohol, fluorosurfactants, or polymers at a concentration of from 0.01% to 5% (of mining waste) can be helpful should soluble carbonates or bicarbonates precipitate from the cured concrète mixture.

Using micro and macro libers currently used in Portland Cernent Concrète at concentrations ranging from 1% to 25% by weight maybe helpful for revising modulus properties to targets, increasing strength, and reducing cracking.

E. Préparation of cernent

Preparing a dry cernent formulation for inclusion into cold fusion concrète mixtures at Ready Mix Concrète or other production facilities can be performed as follows:

Préparé carbonates as indicated above and dry the carbonates. After drying to a constant mass, add the carbonates to a blender and mix with:

about 5 to 15% by weight of a set retarder, e.g., sodium tetraborate, boric acid, or citric acid;

about 0.01 to 2% by weight of an oxide or hydroxide (e.g., magnésium, calcium, potassium, lithium, aluminum) or sulfate (e.g., calcium, magnésium, potassium, lithium) that arrests plastic, drying, and autogenous shrinkage in the mixture, thereby reducing volume change; and grind the materials to a maximum of about 10-micron size, but more preferably about 0.5-to-5-micron size.

The cernent may be used in standard concrète production by mixing the cernent with aggregates (métal carbonates or naturally occurring minerai materials) and water to achieve the desired strength and viscosity. The concrète mixture may be cured normally in ambient conditions, cured with heat, or cured by electrical treatment.

Using zeolites, diatomite, a PVA, fluorosurfactants, or polymers at a concentration of from 0.01% to 5% is helpful should soluble carbonates or bicarbonates precipitate from the cured concrète mixture.
