How to Remove Gold from Ore By: Sapling Team Share Remove the gold from the sand by a process called cyanidation A solution is added to the mix to dissolve the gold Zinc dust is added to separate the gold from the solution The gold is then put through a filter press, which separates it from the solution Step

The two gold refining methods most commonly employed to derive pure gold are: the Miller process and the Wohlwill process The Miller process uses gaseous chlorine to extract impurities when gold is at melting point impurities separate into a layer on the surface of the molten purified gold

Removing the gold bearing rock from the ground is just the first step To isolate pure gold, mining companies use a complex extraction process The first step in this process is breaking down large chunks of rock into smaller pieces At a mill, large machines known as crushers reduce the ore to

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 recovery
