2020-12-1 Gold remains in its raw form after its extraction from the mine. Further processing is needed to receive pure gold. The first step is to crush the parent rock. Next, the pieces go through multiple processes. It depends on the types of minerals and materials combined with the respective gold ore.احصل على السعر
The Miller process is rapid and simple, but it produces gold of only about 99.5 percent purity. The Wohlwill process increases purity to about 99.99 percent by electrolysis. In this process, a casting of impure gold is lowered into an electrolyte solution of hydrochloric acid and gold chloride.احصل على السعر
By 2000 bc the process of purifying gold-silver alloys with salt to remove the silver was developed. The mining of alluvial deposits and, later, lode or vein deposits required crushing prior to gold extraction, and this consumed immense amounts of manpower.
