Hydrometallurgical Processing of Gold-Containing

2021-5-11  This work features a full range of studies on the hydrometallurgical processing of concentrates and gravity tailings, as well as the effects of flotation concentration of gold recovery. The gravity concentrate is resistant to intensive cyanidation (i.e., only 67.07% gold recovery into the solution).

Gold Extraction & Recovery Processes 911 Metallurgist

2016-2-29  There are some considerations related to the concentration process. Recovery is the percentage of gold in the raw ore collected in the concentrate. For example a recovery of 85% means that 85% of the gold is reported in the concentrate and the remaining part is in the tails.
