The mainstream gold beneficiation process flow is generally crushing – grinding – gravity separation – flotation – chemical – smelting.
Gravity separation process and flotation are the most used gold mining methods around the world.
Gravity beneficiation is refers to separating gold ore according to mineral density and plays an important role in contemporary mineral processing methods. The main gravity separator equipment are chute, shaker table, mineral jig, hydrocyclones, etc.
Flotation process is widely used for lode gold processing. In most cases, the flotation method has a good effect in sulfide-containing gold ore with high floatability.
In addition, the flotation process is also used for polymetallic gold-bearing ores such as gold-copper, gold-lead, gold-copper-lead-zinc-sulfur ore.
What’re the limitations of the flotation method? For the ores with particle size greater than 0.2mm, and the quartz gold-bearing ore containing no sulfide, it is not suitable to use the flotation method.
There are amalgamation gold extraction process and cyanide process gold extraction.
The amalgamation process is an old gold extraction process, simple and economical, suitable for the recovery of coarse-grained monomer gold, but it has pollution to the environment and is was gradually replaced by gravity separation, flotation and cyanidation process.
The cyanidation gold extraction process includes cyanide leaching, cyanide pulp washing and filtration, extraction of gold from the cyanating solution or cyanide pulp, and smelting.
Among the gold resources, the amount of low-grade oxidized ore occupies a certain proportion. It is not economical to use the cyanide method to extract gold, and the heap leaching process has economic benefits.
The heap leaching method actually deposits gold-bearing ore on an impervious site and is immersed and leached with a cyanide solution. After dissolving the gold and silver in the ore, the pre-designed grooves along the site flow into the storage tank. The gold-silver-containing liquid is carbon-adsorbed with activated carbon and then desorbed to recover gold and silver.
Placer gold process
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.
Placer gold mine mining
The placer gold deposits are usually mined by gold dredger, hydraulic mining, excavation and underground (shaft) mining.
Placer gold wash plant
–Ore washing. Separate gravel, sand and soil, wash the fine mud adhering to the gravel.
–Screening. Screening the cleaned alluvial gold ore to remove large pieces of gold-free stones will help improve the gold beneficiation efficiency.
–Gravity separation. Coarse gold concentrates are available in the process, so the gravity separation process directly affects the results of the entire placer gold beneficiation.
–Concentration. According to different types of alluvial gold mines, gravity separation amalgamation, etc. can be used to further increase the gold concentrate content.
Placer gold panning equipment
vibrating screen, trommel scrubber machine, sand washing machine, chute, jig concentrator, gold shaker table, etc.
