Abstract:

The pressure leaching is a very efficient hydrometallurgy process with autoclave being the key equipment and technology.This paper systematically reviewed gold and silver concentrate,high iron sphalerite, copper oxide ore and Laterite were treated by pressure leaching from laboratory test,expanded test to the industrial production of the demonstration project in IPE.Respectively,in a tubular autoclave,air stirred autoclave,titanium autoclave and industrial autoclave of 100 m3,these refractory mineral resources were extracted efficiently and cleanly.

Key words: Pressure leaching, Autoclave, Refractory ores, Shop test
