The Cyanidation Process or CYANIDE LEACHING is 'most notably used in the recovery of gold. Safety and environmental concerns are of prime importance in the operation of a cyanidation plant. As we get farther into this type of recovery you will see why. The preparation of the ore for processing is similar to flotation.

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 …

Gold smelting is an essential process in the journey from raw material to pure gold. Smelting is the process of heating and melting the gold concentrate to separate it from other impurities and achieve a higher level of purity. This crucial step plays a significant role in transforming the gold concentrate into a more refined and usable form.
