Gravity Leaching With the ConSep ACACIA Reactor —

2018-9-19 · The ConSep ACACIA Reactor performs a two-fold role. Firstly it increases gravity gold production, leading to a decreased CIP feed grade. Secondly, it removes slow leaching components from the plant leaching circuit. This two fold benefit leads to the following efficiencies: enhancement of the dissolution kinetics; enhancement of the adsorption

Geometallurgical Approach for Implications of Ore

2019-7-22 · The CLR is known for its high amenability to cyanide leaching while the VCR contains refractory minerals such as arsenides, pyrite and pyrrhotite (Gartz and Frimmel 1999). The BR is well known for its deleterious preg-robbing effect due to abundant carbonaceous matter (McLoughlin 2014). A geometallurgical comparison is significant for the discussion of the amenability and recovery rates of low-grade ores during cyanide leaching.

The process design of gold leaching and carbon-in-pulp

2009-8-27 · Leaching reagents in the form of cyanide and an oxidant such as air or oxygen are added after thickening. Leaching takes place in a series of agitated leach reactors or pachucas. Before leaching the pH of the pulp is normally adjusted to a value of around 9.5–11 to ensure minimum loss of cyanide as hydrogen cyanide.
