Procedures for Batteries and metal leaching Tailings with separate Circuits coupled with solvent extraction of metals

摘要

Where the procedures comprise: a) providing a high degree of leaching Solution obtained by leaching of stack or heap a New high-grade ore containing a First metal value; (b) subjecting Said solution to a First solvent extraction of the first value The First aqueous metallic and apply the resulting refined Ore; (c) provide a solutionLeaching of low grade obtained by stack or Heap Leaching of a new or partially leached ore of low grade of the first metal value; and (d) Submit this last solution to a Second extraction with Solvent,Away from the first extraction with Solvent and applying the second refined to separate the resulting aqueous or partially leached ore of low grade, where the refined are not Mixed before being applied to their respective ores leaching.The refined are intermingled in the refined condition applied to the new High Grade ore at least 70% by volume of the refined and the refined First aqueous aqueous applied to new or partially leached ore of low grade at least 70% by volume of the second r Efinado aqueous.The First value is the solution of metallic Copper leaching; leaching Agent includes a selected sulfuric acids, Hydrochloric and nitric; The Second value is recovered from the second refined Cobalt metal
