Use of inorganic, oxy or polyoxy anhydrides, their derivatives, residues and solid waste to increase the recovery of copper and / or the concentration of copper in leaching solution or biofiltration of copper ore

摘要

The invention refers to the use of oxy or polyoxy anhydrides or minerals or compounds resulting therefrom, or solid wastes and liquids and derivatives thereof produced in factories producing oxy or polyoxy salts, Increase the amount of copper recovered from the ore and / or increase the copper content of the solution.In leaching or copper biology. In addition, a kind of leaching solution and a kind of biological filtration process are also introduced, both of which include adding a necessary amount of hydrogen oxide or polyoxyanhydrides, or a compound or a mineral producing the compound, and adding sulfuric acid to the leaching solution or the biological filtration battery at the same time.
