Hydrometallurgy - an overview ScienceDirect Topics

Of course, this also relates to the hydrometallurgical method of production of copper which has its specific features which depend on the processed raw material and also on the type of extraction agents used. In the individual stages of the hydrometallurgical production of copper, it is likely that the most important stage is the stage of the direct transfer of the metal into the solution, i.e. leaching, because it

Hydrometallurgy of precious metals recovery -

1992-6-1 The hydrometallurgical process for the treatment of gold and silver ores remained unchanged for the first 70 years of this century, and consisted essentially of leaching in cyanide solution followed by solid-liquid separation, with the solid residues being washed as efficiently as possible, and the leach liquor being treated by zinc cementation to recover the precious metals.

Hydrometallurgical process for the recovery of tin -

Such a process is both time consuming and expensive and for its economic operation requires a pure high grade tin concentrate. Therefore, a hydrometallurgical process in which the tin oxide in lower grade concentrates is converted at a lower temperature and shorter time into a compound from which the tin can be recovered by leaching and electrolysis is very desirable.
