Leaching of a silicate and carbonate copper ore with

Leaching of metals with carbon‐heterotrophic microorganisms and organic acids as active agents has been performed with Timna copper ore containing 1.1% copper as carbonates and silicate and with some other metal oxides. Aspergillus niger surface cultures on a 14% sucrose fermentation medium yielded 87.3% of total copper from a 10% suspension within 2 weeks of leaching.Get price

LEACHING OF MALACHITE ORE IN AMMONIUM SULFATE

Therefore, when sulfuric acid is employed as lixiviant to extract copper from the ore, other metals in the ore matrix are also dissolved together with the copper during the leaching process. These contaminants that pass into the solution must be removed prior to the electro-winning step of copper to increase both the quality of the final product and the current efficiency of the process.Get price
