Gold Extraction Recovery Processes - 911 Metallurgist

The processing of gold ores has traditionally made use of conventional crushing and grinding circuits. In each case where gold is formed either as coarse native particles or in coarse grained sulphides, it is recovered by gravimetry concentration in the in the comminution circuit in addition to recovery of finer values by leaching. Jigs are the most common types of gravimetric equipment placed to intercept the

Ore Sorting Strategies In Mineral Processing

Ore sorting can be broken down into two broad categories: particle sorting and bulk sorting. Both are dry processes and have the advantage of being able to sense a number of different mineral properties for separation. Particle sorting is for typically for particles larger than 30mm in size and capacity can be somewhat limited. This is due to the fact that each particle is sensed and sorted individually on a conveyor belt. Particles must be in a single layer for processing.
