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 ...

To complicate matters further, these ore bodies are often refractory, where the gold is locked within sulphide minerals; or double refractory, in which gold is locked within sulphide minerals and preg-robbing due to the presence of organic carbon. These must be pretreated ahead of leaching.
