Processingofgold oreshas become a site-specific choice of techniques andprocesses, depending upon mineralogical, chemical, physical, and metallurgical factors. Knowledge of these is therefore important in the formulation of test work for anygold operation.

Exogeneticgoldcan also exist asoxidized ore bodiesthat have formed under aprocesscalled secondary enrichment, in which other metallic elements and sulfides are gradually leached away, leaving behindgoldand insoluble oxide minerals as surface deposits.

In most cases,gold processingwith cyanide leaching, usually with carbon adsorption, is still the core technology and the critical thing is understanding the mineralogy inorderto optimise flowsheet selection and cost drivers, and get the best out of theprocess.

Anotherprocessinvolves groundorebeing passed over plates which are coated with mercury. Thegoldand the mercury form an amalgam, leading to the name of theprocess, amalgamation. Once the amalgam has formed, it is heated until the mercury gas is boiled off, leaving thegold.

For extractinggoldfrom low-gradeores, heap leaching is practiced; huge heaps are sprayed with a dilute solution of sodium cyanide, and this percolates down through the piledore, dissolving thegold.

For extractinggoldfrom low-gradeores, heap leaching is practiced; huge heaps are sprayed with a dilute solution of sodium cyanide, and this percolates down through the piledore, dissolving thegold. There are very well defined rules for the safe and responsible use of cyanide – as laid out in the International Cyanide Code.Gold refining

Goldis usually found alone or alloyed with mercury or silver, but can also be found inoressuch as calaverite, sylvanite, nagyagite, petzite and krennerite. Mostgold orenow comes from either open pit or underground mines. Theoressometimes contain as little as 5/100 of an ounce ofgold…

Mineral Processing. If the mineralogy of theoreshows that you can separate discrete particles of the mineral you want from the gangue components of theore, then it is possible to physically concentrate the valuable mineral and reject the rest. The easiest method for achieving this is by gravity separation.
