Copper Ore Leaching Sx

  • SX-EW (solvent extraction and electrowinning) | KGHM .

    SX-EW technology involves leaching (the process of dissolving useful ingredients with a solution) in atmospheric conditions of copper ore heaps by means of diluted sulphuric acid. Folowing leaching, the pregnant leaching solution is transported via a drainage system to the next stage.

  • Copper Production: How Is Copper Made? - The Balance

    As the acid trickles through the ore, it combines with the copper, producing a weak copper sulfate solution. The so-called 'pregnant' leach solution (or pregnant liquor) is then processed using a hydrometallurgical process known as solvent extraction and electro-winning (or SX-EW).

  • Solvent Extraction Electrowinning VS Cementation: Copper .

    One of the major problems encountered in dump leaching is the precipitation of iron salts that render the ore impermeable to leaching solutions. This condition decreases the copper extraction rate and may eventually produce a dormant dump that may leave much undissolved copper within the ore bed.
