Minerals Processing - Copper Production – PLS / Raffinate . - CiDRAProcess. The processing of copper oxide ore is performed by a hydrometallurgical process called solvent extraction/ electrowinning (SX/EW). The first step, leaching, starts with sprinkling a low concentration of sulphuric acid and water solution on a stockpile of low-grade ore. The liquid percolates through the stockpile.copper production solutions,Copper Production - Metals Planning & Optimization - QuintiqOptimize the entire copper supply chain - from incoming inventory to outgoing logistics - with Quintiq's planning & optimization platform. .
