no gold in solution and is therefore able to extract most of the remaining gold, bringing the total gold recovery (for both steps) up to 97%. A split system is used to achieve the highest possible gold grade in the final solution and also to minimise both electrowinning solution volume and potable water consumption. Elution Tanks

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 ...

Gold Extraction and ... The flotation process in general does not float free gold particles but is particularly effective when gold is associated with sulfide minerals such as pyrites. In a typical pyrytic gold ore, the gold is encapsulated within an iron sulfide crystal structure. Highly oxidized ores generally do not respond well to flotation.
