Of all the methods of extractinggold&processingit from its ore, I used a few to evaluate two principal flowsheets in this case study. The flowsheets utilized operations that involved flotation, cyanidation and gravity concentration. Tests that mirror each of these unit operations were utilized to evaluate the principal flowsheets. This page offers a comparative reviewof gold…

Gold, recognizable by its yellowish cast, is one of the oldest metals used by humans. As far back as the Neolithic period, humans have collectedgoldfrom stream beds, and the actual miningof goldcan be traced as far back as 3500 B.C. , when early Egyptians (the Sumerian culture of Mesopotamia) used minedgold…

Leaching, oftengold, is theprocessof extracting a soluble constituent from a solid by means of a solvent. In extractivemetallurgy,of gold, it is theprocessof dissolving a certain mineral (or minerals) from an ore or a concentrate, or dissolving certain constituents from materials such as a calcines, mattes, scrap alloys, anodic slimes, etc., to achieve either one or two purposes

­The final stageof goldproduction -- refining-- involves removing impurities that remain after the smeltingprocess.Refining companies receive doré bars, as well as scrapgold, and reliquefy the metal in a furnace. Workers add borax and soda ash to the molten metal, which separates the puregold…
