The processing of gold scrap varies not only with the gold content but also with the amenability of the gold in the scrap to extraction. Thus, the bulk of the gold may be recovered by leaching techniques using cyanidation or aqueous chlorination, and the residue may then be treated by smelting to recover the balance.

1.1 PHASES OF A MINING PROJECT There are different phases of a mining project, involve the extraction of ore deposits such as copper, nickel, cobalt, gold, silver, lead, zinc, molybdenum, and platinum. The environmental impacts of large scale mining projects involving these metal ores are the subject of this Guidebook.
Of all the methods of extracting gold & processing it 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 review of gold
The loaded cathodes are rinsed to yield a gold and silver bearing sludge which is dried, mixed with fluxes and put into the furnace. After several hours the molten material is poured into a cascade of moulds producing bars of doré bullion.
Extractive metallurgy is a branch of metallurgical engineering wherein process and methods of extraction of metals from their natural mineral deposits are studied. The field is a materials science, covering all aspects of the types of ore, The final recovery step may involve precipitation, cementation, or an electrometallurgical process
The gold originated in the metamorphic belt in the western Sierra Nevada, which also contains deposits of copper, lead zinc, silver, chromite and other valuable minerals. Currently, California has active mines for gold and silver, and also for non metal minerals like sand and gravel, which are used for construction.

Gold extraction refers to the processes required to extract gold from its ores. This may require a Hydraulic mining was used widely in the Californian gold rush, and involved breaking down alluvial deposits with high pressure jets of water.
THE CHEMISTRY OF THE EXTRACTION OF GOLD Cu(CN); and Cu(CN)! . The insoluble gold cyanide compound AuCN precipitates from acidic solutions of aurocyanide ions as follows: Au(CN); + H+ = AuCN + HCN. (15.2) This reaction takes place readily in strongly acidic solution and slowly in weak acid solutions (pH 2 to 3).
This may include precipitation, distillation, adsorption, and solvent extraction. The final recovery step may involve precipitation, cementation, or an electrometallurgical process. Sometimes, hydrometallurgical processes may be carried out directly on the ore material without any pretreatment steps.
