Placer Gold Recovery Methods

2019-2-5  Specific terms are also used to describe the efficiency of the concentration process. Recovery refers to the percentage of gold in the ore that was collected in the concentrate. A recov- ery of 90% means that 90% of the gold originally in the ore is in the concentrate and the remaining 10% is in the tailings and/ or middlings.
