Definitions
- the prevailing level of technology of the consuming ores is dependent on the mineralogical composition of the USA divided into the following types: sulphide, mixed (oxidized-sulphide) and oxidized.
- sulphide mixed (oxidized-sulphide)
- oxidized oxidized
- the enrichment of sulphide ore by conventional methods of flotation does not cause trouble. Acidic and mixed ores are, as a rule, very convenient. 5
- the degree of extraction of copper and other valuable components to the concentrate is valuable, for example, gray.
- oxidized copper ore is mixed with iron sulfides (alcohol or pyrrhotite) and silk or silk-earth metals. Further, the mixture is burnt at a temperature of 500-800 ° C in a neutral or industrial environment in the presence of distilled water. The purpose of this treatment is to convert the oxidized copper compounds to sulfides, which are easily excreted by selective flotation. This and the preceding process, this method is energy intensive, and its implementation releases toxic fumes and dust. The resulting concentrate extracts 82% of copper and 72% of silver.
- the copper-containing process is separated from the solid phase by filtering.
- this method is only used for copper recovery.
- the method for extracting the sulfur is ineffective because the connection cannot be detected.
- the use of hydroxide sodium is also undesirable due to its high cost of living, toxicity and the difficulty of handling it.
- the task was solved by the method of extinguishing copper-rich, highly-processed ore, which excludes the pulp; sulphidation of the received pulp of the element gray; Flotation of pulses with the receipt of a sulphide concentrate, which is, according to the invention, is at risk of damage to the pulses.
- the proposed method makes it possible to increase the degree of copper extraction to an increase of 92.6%. Otherwise, it is possible to take advantage of the secondary extraction method also with a high degree of extraction reaching 90.2%. Further, the invention makes it possible to significantly reduce harmful emissions into the environmental medium. In addition, the invention eliminates the cost of the process as a result of the exclusion of the stage of leaching of ore and of the copper by-product.
- Sulphidation of pulses is recommended in the presence of a sulphate of sodium or a mineral containing a sulphate of sodium, such as a rehabilitation. This increases the degree of copper extraction and increases it by 98.6%. It is desirable to reduce the weight of the sulphate of sodium or muscle in order to reduce the damage to the environment so that there is one mass part of the element ⁇ ⁇ 88/02408 ⁇ / 51.86 / 0
- the pulp After sulphidation, the pulp is prepared and flotated, and sulphide concentrates are obtained, from which the metal is extracted and processed, and the copper is mined.
- the acidified, ore-rich ore is ground to a particle size of 0.74 mm_. Then, the fraction containing the indicated particles in the amount of 50-100 is mixed, mixed with water and the pulp is mixed with a solid and liquid phase (1: 3).
- the pulp produced by this method introduces an elementary serum with a mass ratio of sulfur to an oxidized copper of 0.2–1.5: 1, which is by weight of 0.5–1% by weight. sera. Further, the pulp, according to the invention, sulphides the melted sulfur.
- the specified quantity of sulphide which is necessary for sulphidation, is divided by the fact that its quantity is less than 0.2 parts by weight. it is not sufficient for the conversion of the residues of all copper contained in the ore, and its quantity, which is higher than the upper, results in 1.5 mass parts, does not increase the resultant loss of output.
- the sulphidation period is 20–120 min.

- Sulshiduyu pulses can be controlled and in the presence of atrocious or tempest.
- the addition of the indicated acids also increases the yield of honey and silver sulgides.
- the recommended consumption of specified materials is 0.7 to 3 parts by weight. for I part by weight elemental element.
- chlorides of sodium or calcium in quantities less than 0.7 mass parts. , there is no significant increase in the yield of sulphides.

- a hermetic reactor for example, an autoclave
- the proposed invention commercially advantageous differs from the known methods.
- An important advantage of the proposed method is an increase in the degree of extraction of copper. If there is a ore, gold, or platinum in the ore, the indicated metals may also be removed completely.
- the proposed method in general minimizes the cost of the gain due to the exclusion of the graduation rate, the quick release, the rest, and the rest ⁇ ⁇ 88/02408 ⁇ ⁇ 86 / 0009
- EXAMPLE I Sulfuric oxidized copper ore contained 1.3% of copper and 10.4 g / t of silver, including 0.93% of copper 0 contained in minerals (from % of copper was found in the form of cc. The specified ore is crushed before it contains 70% of the particles with a size less than 0.74 mm. The crushed ore is mixed with the factory with a mass ratio of ⁇ : F, equal to 1: 1.5. Due to the pulp produced in this way, the elementary system is used with a mass ratio of 0.2-1.5: 1 for copper oxide.
- the pulp is loaded into the autoclave with a volume of I l, equipped with a stirrer, and heated to a temperature of ⁇ 60 ° ⁇ . ⁇ réelle matters ⁇ réelle ⁇ réelle ⁇ ⁇ 88/02408 ⁇ / ⁇ 86 /
- the elementary series is, and this is, a quantity of 1.2: 1.
- the results of copper extraction are • a flat percentage in the specified range of the variation in the cost of the sodium sulfate and the human condition is shown in Table 3.
- the original ore contained 1.22% of copper, including 1.10% of the minerals contained in minerals (ores, malachite, and azure).
- We were enriched under the conditions of the type I Sprint and ⁇ : W ⁇ : 0.5 and the quantity of the enterable season, equal to 0.75: 1.
- Copper recovery was 85.0%.
- the resulting copper-sulfide concentration in the amount of 1.5-3 of the mass of the original ore is returned to the production of the new source pulp.
- the waste of the sulfur used for sulphidation is reduced, since the reduction of the sulfur is increased by the sulfur in the concentrate.
- the results of ore beneficiation in the case of a waste of 0.2: 1, depending on the amount of return, are shown in Table 6. ) 88/02408 ⁇ S ⁇ / 5 ⁇ '86/0009
