Gold Extraction & Recovery Processes

Sometimes the gold is very difficult to recover because the gold is associated with sulphide mineral in a way that can be considered difficult to the usual recovery techniques. The factors that can affect free gold floatability are particle size, flakiness, composition, surface contaminants, collector type and loading, and cell type.
