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 ...

Extraction of gold using cyanide Gold is found in very low concentrations in the ore from which it is mined. To collect the gold from the ore it needs to be separated from the other minerals in the ore. To do this the gold needs to be made into a soluble form so that it can be separated from the other minerals as gold is insoluble.
lurgical gold extraction routes utilize a leaching step to produce a goldbearing solution as an intermediate product while the recycling of secondary gold from electronic and precious metal scrap is based on the selective and fast dissolution of the precious metal. Therefore, A Method for Leaching or Dissolving Gold from Ores or Precious

Extractive metallurgy as a discipline deals with the extraction of metals from naturally occurring and man made resources. Separation is the essence of metal extraction. ... Gold is found in native state Aggregates of minerals (or ores) — mostly oxides and sulphides, example Al, Fe (oxide ores), Cu, Pb, Zn, Ni etc (sulphide ores).
gold miners Smallscale miners Some SSM communities continue to practice the same method of gold extraction developed by their forefathers, whereas other groups are innovative and try to improve working techniques to increase gold recovery rates. An excellent example of this is a group of SSM in the Benguet province in the Philippines.
Bromine acts more energetically than chlorine, and has also been employed in the extraction. The recovery of the gold is effected similarly, and the bromine is then liberated by the action of chlorine, but it is impossible to prevent loss of bromine. Cyanideprocess The extraction of gold by the cyanidemethod is of great technical importance.

Regardless of the solvent used, a black tar collects on the bottom. This needs to be clarified with dilute acetic acid; I highly recommend adding several portions of AcOH (several extractions), using an ultrasonic bath for several minutes (1015m).
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.
