Every gram of gold from the stones is indispensable to experience mining – crushing – grinding – sorting – smelting – casting, etc., from the perspective of mineral processing, the crushing is the first mineral beneficiation process step, and it is almost a preparatory section for any gold processing plant.
Ore is stockpiled (1) at the processing plant, and the process begins by feeding the ore into a hopper with a loader. The ore is conveyed, and lime is added (2) to raise the pH of the ore. Following crushing through a jaw crusher (3), the ore is fed into the semi autogenous grinding (SAG) mill (4) along with water and steel balls.
Gold Ore Processing Equipment. Usually, in small scale gold ore, equipment used from mining equipment to the all beneficiation processing line are blasting, transmission, feeding, crushing, conveying, grinding, extracting (flotation, magnetic separation, electrostatic ore dressing, mix mercury and chemical method).
The gold content in the placer gold mine is extremely low, and it is known as the gold panning by beneficiate the placer gold through various energy-efficient placer gold equipment. Among various gold extraction methods, the gravity separator method is energy-saving, efficient, environmentally friendly, and is suitable for placer gold ore process.
That''s why one must purchase premium gold ore crusher machine that ensure efficient and effective extraction and processing of metals. There are a number of gold ore crusher machine available for purchase on Alibaba.com with just a few clicks. For example, the stone crushers are used for crushing stones and hard rocks fed into it.

Most gold ore mining needs the three closed-circuit process of coarse, secondery, fine crushing and screening operation, also three closed-circuit or open circuit process is availiable. For large gold ore mining Primary gold ore crusher: large jaw crusher or mobile jaw crusher Secondery gold ore crusher: standard cone crusher
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.
2. The Extraction Processes of Gold-Pyrite Ore. The treatment principle of gold-pyrite ore is to separate the sulfide from the gangue and dissolve the gold in the cyanide solution. In order to remove antimony, arsenic, carbon and other substances that absorb fluoride, roasting treatment is required before cyanidation.
