Hyclrometallurgy of copper

Hyclrometallurgy of copper : suitable for small and medium sized copper oxide and half oxide copper ore , mainly divided into Heap leaching, agitation leaching (bath leaching), pool leaching, extraction, washing and stripping of copper leaching solution Electrodeposition, etc.. Jinpeng offers a full range of equipment, techniques, and methods. capacity: 100-10000T/D

Hydrometallurgical process

Hydrometallurgical process suitable for small and medium sized copper oxide and  half oxide copper ore  , mainly divided into Heap leaching, agitation leaching (bath leaching), pool leaching, extraction, washing and stripping of copper leaching solution,Electrodeposition, etc..

 1. heap leaching Heap leaching of ore crushing, including mattress laying, heap, cloth tube, drip (spray), consistent with the gold heap leaching, spray pump must use the anti corrosion pump;

2. stir leaching (trough leaching)

 Including crushing and sieving, grinding, acid leaching, washing, clarification (filtering), tailings disposal, and gold leaching leaching is similar, in the anticorrosion treatment of the acid leaching tank for the (usually two slot), washing machine also has dense leaching, leaching time than gold leaching time is short.

3.pool leaching (infiltration tank leaching)

Percolation tank brick, cement mortar, lined with HDPE film preservation, within the bottom (wood and bamboo production), similar to percolation tank of gold; The first shop floor before filling, then extract outlet plug, then manual or machinery will be crushed ore (less than 10mm) evenly into the tank, adding leaching agent with good, soak a few hours or a few days after discharge; production is often used in a plurality of percolation tank operation at the same time, leaching solution in order to keep sending follow-up treatment to component concentration is constant.

Extraction, washing and stripping of copper leaching solution (noble liquid)

1.The purpose of extraction (function)

The extraction of low concentration and impure leaching solution into an electrolyte rich in Cu2+ and high purity is an extraction process, most of the copper leaching solution has the following properties: the content of copper ions is low (16kgCu2+/m3); the more impurity content (110kgFe/m3); Industrial electroplating requires pure electrolyte, rich in copper ions greater than 35 kg/m3

 2. extraction cycle

Solvent extraction refers to metal ions from a liquid phase into another liquid and the liquid mutually immiscible phase material phase transition process; one phase containing water solution of price components, the other phase is an organic solvent, so called solvent extraction.
