Definitions
- the present invention relates to the use of compositions of alkylammonium salts and amine alkoxylate esters in the flotation of silicate-containing minerals and ores.
- Calcium carbonate is purified from silicate-containing and color-providing minerals with the aid of quaternary ammonium salts based on fatty acids or fatty alkylimidazoline compounds. Since calcium carbonate is used in addition to kaolin, rutile and talc as a white pigment in paper and plastic production, the highest possible whiteness or a low concentration of coloring minerals is desired. Due to the hardness of silicate, this would also lead to increased wear on the calenders of paper machines in papermaking. Therefore, calcium carbonate is purified in addition to dry processing via the flotation process.
- silicate content which in the case of calcium carbonate is often characterized as an acid-insoluble constituent, below 1.0% by weight.
- the content of silicate in the task can vary and in some cases be from 10 to 20% by weight.
- fatty amines, alkyl ether amines, alkyl ether diamines or quaternary ammonium salt compounds are used as silicate collectors. These are also known under the trade name Flotigam ®.
- WO-A-00/62937 discloses the use of quaternary ammonium salts for flotation of iron ore.
- EP-A-0 876 222 describes the use of biodegradable esterquats as collectors for the flotation of non-sulphidic ores.
- U.S. 4,995,965 discloses the use of hydroxypropylated quaternary ammonium salts, unsymmetrically substituted dimethyldialkylammonium salts and dialkylhexahydropyrimidine compounds as the reverse flotation collector of calcium carbonate.
- CA-A-1 187 212 discloses quaternary ammonium salts and bis-imidazolines as collectors in silicate flotation.
- US Pat. No. 5,720,873 discloses a collector for silicate flotation comprising an amine alkoxylate in addition to a quaternary ammonium compound.
- a collector combination of an alkylammonium salt and an amine alkoxylate ester discharges less calcite fine grain than the previously described collector and collector combinations and thereby the recycling of valuable material is significantly improved, without thereby increasing the content of silicates in the concentrate.
- the invention relates to the use of a composition
- R 1 is a Ce- to C 24 -alkyl or alkenyl radical
- R 2 , R 3 , R 4 independently of one another H or a Cs to C 24 acyl radical
- Ce to C 24 acyl rest is x, y, z independently of one another an integer from 0 to 50 with the
- x + y + z is an integer of 1 to 100, in amounts of 10 to 5000 g / ton of ore as a collector in silicate flotation.
- Another object of the invention is a method for flotation of silicate-containing mineral by bringing a composition of A) and B) with the silicate-containing mineral in contact.
- Another object of the invention is a composition containing 1 to 99 wt .-% of component A) and 1 to 99 wt .-% of component B).
- composition of A) and B) is also referred to below as a collector according to the invention.
- the quaternary ammonium compound which constitutes constituent A) is a tetraalkylammonium salt of formula (2)
- R 6 , R 7 independently of one another C 1 - to C 6 -alkyl groups or benzyl groups
- R 8 , R 9 independently of one another C 8 - to C 36 -alkyl groups or alkenyl groups
- X is an anion
- Esterquats according to the formula (3) are further preferred embodiments of the quaternary ammonium compound according to constituent A),
- R 10 , R 11 , R 12 independently of one another are H or C 8 - to C 24 -acyl groups
- R 5 is a C 1 - to C 6 -alkyl group or a benzyl group
- k, I, m are integers from 0 to 5
- X is an anion, preferably Cl or CH 3 SO 4 .
- R 1 , R 8 and R 9 independently represent a linear or branched alkyl or alkenyl group. It is preferred that the radicals comprise 8 to 18 carbon atoms. Particularly preferred are 2-ethylhexyl, isononyl, isodecyl and Isotridecyl- and dodecyl radicals.
- R 2 , R 3 , R 4 , R 10 , R 11 and R 12 are acyl radicals having 8 to 24 carbon atoms.
- the acyl radicals preferably comprise 10 to 18 carbon atoms. They can be linear or branched.
- the acyl radicals can be saturated or unsaturated.
- Preferred acyl radicals are stearoyl and oleoyl radicals.
- Component A) of the collector according to the invention contains at least one bound to the ammonium nitrogen, optionally heteroatom-containing organic radical having 8 to 36 carbon atoms.
- the radical may preferably be an alkyl, alkenyl or acyl radical, which is furthermore preferably designed as disclosed for R 1 or R 2 .
- A is in particular either an ethylene - (- C 2 H 4 -), a propylene - (- C 3 H 6 -) or a butylene group (-C 4 Hs-).
- A is an ethylene group.
- B is in particular either an ethylene - (- C 2 H 4 -), a propylene - (- C 3 H 6 -) or a butylene group (-C 4 H 8 -).
- B is an isopropylene group.
- k, I and m are preferably independently of one another 2, 3 or 4, in particular 3.
- x, y and z preferably give an integer of 15 to 30, in particular 20 to 25.
- the amino ethoxylate ester constituting component B) is in the form of its mono- or di-ammonium salts obtained by neutralization with both organic and mineral acids.
- the components A) and B) of the collector according to the invention can be used together with other collectors of the prior art, which are different from A) and B). Examples of such other collectors other than A) and B) are
- R 14 is a hydrocarbon group of 1 to 40, preferably 8 to 32 carbon atoms and R 13 is an aliphatic hydrocarbon group of 2 to 4 carbon atoms;
- R 17 is a hydrocarbon group having 1 to 40, preferably 8 to 32 carbon atoms, R 15 and R 16 is one or more aliphatic hydrocarbon group having 2 to 4 carbon atoms;
- R 21 , R 18 , R 19 and R 20 one or more hydrocarbon groups
- R 23 is a linear or branched alkyl group or alkenyl group having 6 to 24 carbon atoms and D is a C 2 - to C 4 alkylene group.
- collector according to the invention can also be carried out in combination with foaming agents and pushers, as known from the prior art.
- hydrophilic polysaccharides such as modified starch, carboxymethylcellulose, or gum arabic in dosages of 10 to 1000 g / ton are added as a pusher.
- the silicate flotation is preferably carried out at a pH of 6 to 12, in particular 8 to 11, which is set, for example, with sodium hydroxide.
- the use according to the invention can be carried out both in direct and in reverse silicate flotation.
- the use of the present invention is also useful in freeing silicate sand from impurities by flotatively separating the silicate sand from the contaminants using the compound of A) and B).
- the preferred addition amount of the collector according to the invention is 100 to 1500 g / ton of ore, in particular 500 to 600 g / ton of ore.
- the laboratory flotation experiments were carried out using a Denver flotation machine, type D 12 in a 2.5 L glass cell, whereby the pulp level was kept at the same level by constant addition of drinking water.
- the slurry contained 130 g of solid per liter.
- Example 1 Ground calcite, 100% ⁇ 250 microns, containing about 12 wt .-% silicate minerals, such as quartz, mica, and graphite, was transferred to a 2.5 L glass cell. The flotation pulp was then adjusted with drinking water to a content of 130 g solids per liter of pulp. The conditioning of the flotation pulp and the subsequent flotation was carried out with a DENVER flotation machine, type D-12. For flotation of the graphite, the flotation pulp was first conditioned with 20 g / t of a pine oil. The pine oil was added undiluted to the pulp and conditioned for 1 min. The graphite was floated in the foam phase (graphite flotation mountains). The flotation time was completed after 3 min.
- the chamber product was then subjected to a silicate flotation, wherein the silicates were swelled in the foam phase (silicate flotation mountains). In the flotation cell remained the purified calcite (concentrate). The silicate collectors were added undiluted to the flotation pulp and left for 1 min. conditioned. The subsequent silicate flotation was complete after 4 min.
- the flotation fractions (graphite flotation, Silikatflotationsberge and concentrate) were dehydrated, dried, weighed and dissolved to determine the acid-insoluble content in 25% HCl solution.
- the acid-insoluble component (AIR) of the concentrate is a quality feature.
- dicocoalkyldimethylammonium chloride (standard collector 1), dioleoyloxyethyl-hydroxyethylmethylammonium methosulfate (standard collector 2) and tallow fatty propylenediamine with 40 moles of EO (standard collector 3) were used.
- Standard collector 1 dicocoalkyldimethylammonium chloride
- Standard collector 2 Dioleoyloxyethyl-hydroxyethylmethylammonium methosulfate
- Standard collector 1 dicocoalkyldimethylammonium chloride
- Standard collector 3 tallow fat propylenediamine with 40 mol EO
