The process mineralogy of gold: The classification of ore

The principal gold minerals that affect the processing of gold ores are native gold, electrum, Au-Ag tellurides, aurostibite, maldonite, and auricupride. In addition, submicroscopic (solid solution) gold, principally in arsenopyrite and pyrite, is also important. The main causes of refractory gold ores are submicroscopic gold, the Au-Ag tellurides, and very fine-grained gold (lt;10 m Get price

How Gold Is Refined: A Step

Even once the gold has been extracted from the earth, it's still in its raw form. It's still just raw ore that requires processing before it becomes pure gold. First, the ore is crushed. It then undergoes a series of processes that will vary depending on the different Get price

Mineral Processing Solutions

Focussing on the gold industry, Gekko replace high-energy whole ore treatment of gold by carbon-in-leach (CIL) methodologies with beneficial low-energy process solutions. Harnessing both gravity separation and floatation, as well as dramatically reducing the initial mass to be processed by pre-concentration, Gekko flowsheets increase the grade for downstream intensive processing.

Processing, smelting and refining gold

When gold dissolution is complete, the gold-bearing solution is separated from the solids. With ores of higher gold content (greater than 20 grams of gold per tonne of ore), cyanidation is accomplished by vat leaching, which involves holding a slurry of ore and solvent in large tanks equipped with agitators.
