Good mineral processing equipment production line configuration can save cost, a high recovery rate, the gold ore dressing equipment production line for the purpose of selecting fine gold, finally finished gold smelting. As the most important mechanical equipment in the mining machinery industry, the quality of gold dressing equipment affects the service life of the mineral processing equipment, which is related to the economic benefits of the mineral processing enterprises. The quality of the ore dressing depends on the gold dressing method and the process of gold dressing.
How can the production line of gold ore dressing equipment be configured to improve the production and quality of gold mining?
According to different ore properties (the different associated ores), different ore dressing methods are used to determine the beneficiation process according to different methods. According to the distribution characteristics of gold ore resources in China, the main mineral processing techniques are the following.
1, gold ore dressing method - flotation process:
In China, 80% of the gold concentrates are selected by flotation, and the output of the concentrate is sent to the nonferrous smelter. Due to the increasing development of cyaniding and enterprise to improve economic efficiency, reduce concentrate transportation loss, take in situ treatment, flotation process have larger development, occupies an important position in gold production.
2. Gold ore dressing method - reelection process:
The gravity separation method is the method of separating ore according to the density difference of mineral. The main equipment used is chute, rocking bed, jigger and short cone cyclone. 3. Gold ore dressing method - chemical process:
At present, the main method and cyaniding technology of gold amalgamation process. Gold amalgamation process is an ancient gold extraction process, which is simple, economical, suitable for coarse monomer gold recovery, but has great pollution to the environment, has been gradually replaced by gravity separation, flotation and cyaniding process. 4, cyaniding technology:
Some basic processes, such as cyanide leaching, washing and filtration of leaching pulp, extraction of gold in cyanide or cyanide pulp and smelting of finished products, etc.
There are a variety of different gold beneficiation process, but most of the cases are divided into wet and dry separation of the two, because there are different rules of various types of mineral water content contained, so according to the content of mineral water was the most suitable processing method of gold ore dressing equipment.
The water content of the mineral is saturated if the ore dressing equipment is wet selected, washed by the sand washing machine, or the flotation process of the flotation machine. Because heap leaching is normally used to processing some low grade ore dressing, in this case, the tailings and waste rocks were seldom recovered, and in the production of the main, the selection of the material yield is very low, but the gold ore dressing equipment can solve these defects and have a qualitative improvement in equipment technology.
To determine the beneficiation process, the process of ore dressing process of gold will gradually clear, the gold separation flotation process as an example, the beneficiation process is mainly: silo, jaw crusher, cone crusher, tank washer, belt conveyor, spiral classifier, and shaker, energy-saving ball mill self suction flotation machine - high efficiency thickener, leaching.
