For the past 100 years, the key element in the processing of gold ore has been the cyanidation process.Over the years, steady improvements have occurred in equipment design; milling has evolved from stamp mills, through tube mills and ball mills to the large semiautogenous grinding (SAG) and fully autogenous grinding (FAG) circuits in modernGuides For High-sulfide Gold Processing,17-03-2020· High sulfide gold ore refers to 20% -30% of gold wrapped by sulfide (mainly pyrite). It is better to use gravity separation, flotation, or flotation-cyanidation process. The following is an analysis of specific beneficiationOre processing – Waihi Gold,The slurry that remains after this process has a very fine particle size. Typically, 80% of the ore particles are less than 70 microns in size (about the same consistency as fine beach sand). Such a fine particle size is required for gold liberation – the size required for the cyanide to be able to ‘see’ the gold in the leaching process.Gold Process Mineralogy - SGS,Gold process mineralogy address all issues related to gold ore processing by the detailed study of an ore or a mill product.
