Mining and production of non-ferrous metals

Promising and effective method for the production of non-ferrous metals from poor ores is hydrometallurgy. Method of mineral separation, flotation get sulfide mineral concentrates. The method is based on the principle that different minerals react with chemical reagent at different pH levels. Using lime to control pH, extract valuable sulphide base metal (copper, Nickel, cobalt, zinc and lead). Methods hydrometallurgy also received lithium, magnesium and beryllium.

Aluminium, gold

In the production of aluminium from bauxite first, get oxide Al₂ O₃. Gold production is produced by the method of cyanidation. Cyanide leach ore, extracting the gold in the solution from which it subsequently turns into metal. Refractory gold ore usually contains iron sulfide (usually pyrite, FeS₂), which must be oxidized and removed before cyanidation.

Copper, cobalt

Hydrometallurgical processing of ores of copper/cobalt oxide dilution of the ore with acid. The obtained acidic solution requires even deposition of the dissolved elements in the solution.

Nickel

Hydrometallurgical processing of Nickel laterites (limonites or saprolites) requires conditions for the dissolution of Nickel in lateritic ore. This acidic solution is neutralized in several stages using lime, the precipitating of dissolved impurity elements from the solution and removing valuable metals (Ni, Co, Cu) in the form of deposition.

Recovery of silver

Silver is recovered from refractory sulfide gold ores. During the oxidation under pressure or as a result of autoclave processing of certain types of silver ore can be moved to the residual Coosada in the basic sulfates of iron, preventing its extraction. You can use the process of boiling lime: at high temperature the precipitated silver precipitation react with lime. This leads to their transformation into oxides and/or hydroxides of iron with subsequent recovery of the silver.

The use of sulfuric acid in hydrometallurgy

In the production of TiO₂ from ilmenite FeTiO₃ used sulfuric acid. Limestone and lime required for the neutralization of waste waters and removal of dissolved metallic impurities.

Sulfuric acid is used for leaching of uranium from certain types of ore, often together with an oxidizing agent such as ferric iron. This leaching takes place either on location or in a stirred tank. After extraction of the uranium from solution (usually by solvent extraction) the final processing requires neutralization of acid and removal of dissolved metals.
