Production technology, gained calcining and dilute sulfuric acid carry out acidleach, output cupric pickle liquor, gained cupric acidleach under the conditions of certain acidleach
Enter extraction electrodeposition technique after liquid, extraction is the key step of modern wet-milling processing (Leaching-solvent Extraction-electrowinning Technology, L-SX-EW)
Suddenly.With the exploitation of efficient, stable copper extractant, the hydrometallurgy of copper has obtained huge development.Currently, the whole world 20%
Copper is produced by Extraction electrodeposition technique.
Although good recycling, the zinc contained in Gold Concentrate under Normal Pressure can be obtained by traditional Extraction electrodeposition technique in copper metal
The recycling of metal is but always a problem, and the zinc metal contained in Gold Concentrate under Normal Pressure is leached during acidleach with copper together, existing
In some technique, the raffinate waste liquid (containing remaining a small amount of copper simultaneously) containing zinc is by the way of lime neutralization
Reason not only causes the waste of zinc resource, but also neutralize higher cost, institute so that zinc enters the bottom ash of lime neutralization in this way
Bottom ash can partially be sold to cement plant and do raw materials for production, remainder can only be stored up, and not only take up a large amount of soils in this way, and right
Ambient enviroment causes to seriously affect, and with national conservation-minded society, the proposition of environment-friendly type social construction, carries out in cupric pickle liquor
The research and application of the effectively recycling, reduction outlet and neutralisation treatment cost direction of metallic zinc are rather important.
