The gravity concentration separation process gets more complex as the specific gravities between the valuable mineral and the gangue get closer. For example, complex gold in a sulphide complex of pyrite, must isolate a specific gravity of 19.3 for gold from 5.2 for pyrite.
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 ...

The ground ore is then floated to produce a gold rich copper concentrate for filtration and sale to overseas smelters. Flotation tailings are then leached for further gold recovery. The ore processing rate is approximately 35 million tonnes per annum. Typical head grade is approximately 0.8 gram per tonne gold and 0.11 per cent copper.
This method has applications in various stages of a flowsheet; from initial processing to final upgrading. Some of the earliest methods were utilized by the prospectors of the gold rush where they used simple panning techniques to concentrate their ore. Though rudimentary, it is still an applicable process today.
The hashing stage (corresponding to metal extraction and recovery stages) is a little more complex for gold ores, as the optimal process flowsheet selection choice is heavily dependent on a good understanding of two fundamental geometallurgical parameters, the gold mineralogical associations, and the gold particle size and liberation ...

It has been said that gold was one of the first metals to be mined. As deposits with free, coarse gold were depleted and the volume of mining increased, process flowsheet design became more and more complicated. Gravity was the first method developed to recover gold from ore.
