The flotation tailings have a residual gold content that is recovered in a carboninleach circuit. In addition, at Phoenix, copper heap leaching is performed on copper oxide ore and enriched copper sulfide ore to produce copper cathodes.
Measuring pH in Cyanide Leaching Emerson
The activated carbon adsorbs the gold cyanide complex on the surface of the carbon particles. Later, the carbon is washed with hot caustic to remove the gold and then rinsed with acid to regenerate the carbon particles for reuse. In heap leaching, the carbon is usually held in a fixed column and the solution is passed over the columns repeatedly.

Cyanide Leaching | Mining | SGS Argentina
Heap Leaching. Heap leaching facilitates the profitable extraction of gold from very low grade ore. Prior to heap leaching, either run of mine (ROM) or crushed ore is heaped into structures 10 to 20m high that are stacked on an impermeable layer. A dilute cyanide solution is sprayed on the heap, percolates through the pile and dissolves the ...

Heap leaching Heap leaching applies often to lowgrade ore. The processing plant stacks the ore in a heap on an impermeable liner. Stacking is often preceded by a crushing step to increase the surface area of the ore and permeability of the heap. A sprinkler system above the heap then applies a leaching solution.
What Are Commonly Used Gold Recovery Chemicals?
Gold recovery chemicals is the reagent that used to extract gold, which is one of necessary element in gold processing plant. The commonly used gold recovery chemicals can be mainly divided into three types: flotation chemicals, heap leaching chemicals and cyanidation leaching (CIL, CIP) chemicals. Gold recovery industry has important economic significance, but the content of gold in most ore is .
