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. This page offers a comparative review of gold recovery .

Present day placer mining uses pans, water and gravity, just like the prospector of 1849, only on a larger scale. This "modern" placer technology only recovers up to 40% of the gold from every ton of ore concentrate (finely ground ore) as it primarily targets nuggets and flakes of gold. The remaining 60% goes untouched.

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.
