  • MMG Limited Extraction and Processing

    After mining, Copper Oxide ore delivered to the ROM stockpiles is fed into the processing plant through a mineral sizer followed by a semiautogenous grinding mill (SAG mill). Copper is produced primarily by an agitated leach, counter current decantation and solvent extraction and electrowinning (SXEX) process.

  • Solvent extraction and electrowinning Wikipedia

    Solvent extraction and electrowinning (SX/EW) is a twostage hydrometallurgical process that first extracts and upgrades copper ions from lowgrade leach solutions into a solvent containing a chemical that selectively reacts with and binds the copper in the solvent. The copper is extracted from the solvent with strong

    Feb 28, 2017 One possible appliion is for a site with a number of stered small ore deposits. Each deposit could have a satellite leach/SX/copper sulphate facility feeding a central EW plant. Another possibility is to transport the copper sulphate to an EW plant at another loion with lower power unit cost.

    The coarser ore goes to the heap leach, where the copper is subjected to a dilute sulfuric acid solution to dissolve the copper. Then the leach solution containing the dissolved copper is subjected to a process called solvent extraction (SX). The SX process concentrates and purifies the copper leach solution so the copper
