How to Fix Agitator Mixer Problems in a Gold Leach

2020-10-6  A cyanide leaching circuit usually consists of large agitated tanks for mixing mineral slurry with cyanide in order to extract gold. Typically, the slurry consists of 30-40% solids by weight with the solid particles being less than 100 microns (0.1mm) in size. Air or oxygen is often bubbled through the slurry to improve the leaching reaction.

Gold Agitation Cyanidation Leaching

2019-10-18  The agitation leaching method is to concentrate the slurry, obtained after grinding and classifying of the gold-containing ore, to a suitable concentration, place it in a leaching tank, add a cyanide solution, and aerate to carry out leaching. The main equipment used in the agitation leaching process is a cyanide leaching tank.

In 2012, it was decided that agitation leaching should be introduced to operate in parallel withheap leaching, high grade ore (> 1 g/t Au) going to agitation leaching and low grade ore (< 1 g/t Au) going to heap leaching. Accordingly, a 100 t/h stand-

Leaching Low-Grade Gold Ores SpringerLink

Multistage agitation leaching followed by elaborate solids-liquid separation is required to recover most of the gold (up to approximately 95%) in solution, in a reasonably short time (see Chapter 4). Large tonnage of a relatively high-gold-content ore is a prerequisite for the substantial capital and operating costs required for milling.
