The principle of gold placer beneficiation is to first use gravity separation to recover gold and gold from the raw ore to the maximum extent. The various heavy minerals associated with it are then separated from each other by gravity separation, flotation, mercury amalgamation, magnetic separation and electrostatic separation to achieve the purpose of comprehensive recovery. Placer gold ore separation is generally divided into processes such as desliming, separation, crushing and screening.
Desliming: Materials smaller than .mm in placer gold mines generally contain no gold or very little gold. Gold smaller than .mm is commonly known as floating gold and is difficult to recover during the sorting process. However, slime of the same particle size interferes with the sorting process, especially the mechanical sorting process. Therefore, in placer gold mechanical beneficiation plants, we always try to remove slime smaller than .mm. The commonly used desliming equipment in production is desliming buckets of various specifications. The chute allows a wide range of material particle sizes and a large processing capacity, so the sulfur tank often does not need to be deslimed before sorting.
Separation: Practice has proven that gravity separation is an effective and economical method for treating placer gold ores. Since the particle size composition of gold in placer gold ore is different, the effective particle size limits of materials processed by various gravity separation equipment are also different, so a reasonable placer gold ore separation process should be a joint operation of several gravity separation equipment.
Crushing and screening Many placer gold ores contain cemented mud clumps, some of which have particle sizes larger than millimeters. If these mud clumps are not broken down, they will be eliminated along with the waste rock during the screening process, resulting in the loss of gold. loss. In addition, the cement can also be cemented on gravel or pebbles. If it is not broken down, gold will be lost during the screening process.
