Processing, smelting and refining goldWorld Gold Council

When gold dissolution is complete, the gold bearing solution is separated from the solids. With ores of higher gold content (greater than 20 grams of gold per tonne of ore), cyanidation is accomplished by vat leaching, which involves holding a slurry of ore and solvent in large tanks equipped with agitators.

Gold and silver are obtained from a variety of ores. Most people think of nuggets and such, but the truth is that very little comes from nuggetsnearly all newly mined gold comes from ores mined from the natural hard rocks that contain gold in tiny, even microscopic particles.

Gold Processing Methods & Gold Ore Extraction

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.

What Is Gold Smelting? (with pictures)

019· Gold smelting is a metallurgical process used to separate metal from ore, rocks that contain gold. The ore is ground and treated with chemicals to remove some impurities before being heated at high temperatures with a flux that triggers a chemical reaction, causing the metal to precipitate out of the mixture.

Historically, mercury was used extensively in placer gold mining in order to form mercury gold amalgam with smaller gold particles, and thereby increase the gold recovery rates. Large scale use of mercury stopped in the 1960s. However, mercury is still used in artisanal and small scale gold mining (ASGM), often clandestine, gold prospecting.
