Nowadays, the gold beneficiation process, generally through the stone crusher crushing, and then into the ultra-vertical grinding mill crushing, and then after re-election and flotation, extracted out of the concentrate and tailings, and then through the chemical method, and finally smelted out of the final product of gold.
Gold ore dressing process can be understood as:
Raw ore from the vibrating feeder through the jaw crusher after the first stage of crushing into the vibrating screen screening, the upper products need to be re-crushed after crushing with the middle products together with the second stage of impact crushing, the second stage of crushing products return to merge with the first stage of crushing products and screening. The screened products are ground through the first section of the super-vertical mill and form a closed-circuit grinding with the classification mechanism, and its classification overflow is classified by the cyclone and then entered into the second section of the ball mill for regrinding and then flotation.
Crushing and Grinding
The crushing process adopts jaw crusher for coarse crushing, standard cone crusher for medium crushing, and short-head type cone crusher and roll crusher for fine crushing. Most of the small and medium-sized gold processing plants adopt two-stage and one closed-circuit crushing, while large gold processing plants adopt three-stage and one closed-circuit crushing process. In order to improve the output and equipment utilization factor, the beneficiation plant generally follows the principle of more crushing and less grinding, and reduces the particle size of the ore to be ground.
Re-election
Re-election is a method of separating ore according to the difference in mineral density, and the main equipment used are chute, shaking table, jigger and short cone cyclone, etc. The main equipment used are chute, shaking table, jigger and short cone cyclone.
Flotation
80% of gold processing plants use flotation method to select gold, and the output concentrate is mostly sent to non-ferrous smelters for processing. Due to the increasing development of cyanide extraction of gold and enterprises to improve economic efficiency, reduce the loss of concentrate transportation, more to take the local treatment, flotation process has a greater development, in the gold processing production occupies a fairly important position.
Gold ore dressing methods - chemical separation
The current chemical separation methods mainly include amalgamation gold extraction process and cyanidation gold extraction process. Amalgamated gold extraction process is an ancient gold extraction process, both simple, and economic, suitable for the recovery of coarse-grained monomer gold, but there is a great deal of pollution for the environment, and gradually replaced by re-election, flotation and cyanide gold extraction process. Cyanidation gold extraction process includes: cyanide leaching, washing and filtration of leaching slurry, extraction of gold from cyanide liquid or cyanide slurry, and smelting of finished products and other basic processes.
Gold ore dressing method - smelting
Smelting is the last process of gold extraction, and smelting is divided into roughing and refining. Gold smelting is developing rapidly in our country, and most of them adopt the traditional crucible method of smelting to produce composite gold, or send it to non-ferrous metal smelters to process and refine the finished products.
