Gold ore beneficiation method 1, this single flotation process flow for processing fine gold particles, can be high floating sulfide ores and gold-bearing quartz veins polymetallic sulfide ores containing gold and carbonaceous (graphite) ores. 2. The process of amalgamation-flotation combined process is to first recover the coarse gold and the mixed mercury tailings in the ore by amalgamation. This process is used to treat a single flotation treated ore, gold-bearing oxidized ore, and ore associated with free gold. The use of this process has a higher recovery rate than a single flotation process. 3. Re-election (amalgamation)-cyanide combined process This process is used to treat quartz vein-containing gold oxide ore. The ore is first re-elected, and the obtained concentrate is re-selected for mercury amalgamation; or the ore is directly mixed with mercury, and the tailings, graded ore, and mixed sand are separately cyanated. 4. The whole mud cyanidation (direct cyanidation) process gold is produced in the quartz vein ore in the state of fine or fine particle dispersion. The ore is deeply oxidized and does not contain Cu, As, Sb, Bi and carbonaceous materials. Such ore is best suited for the full mud cyanidation process. Gold ore dressing equipment Flotation machine: The flotation machine drives the impeller to rotate by the motor's V-belt drive, which generates centrifugal force to form negative pressure. On the one hand, it absorbs sufficient air and mixes with the slurry. On the one hand, it mixes the slurry with the drug, and refines the foam to make the mineral bond. Above the foam, float to the pulp surface to form a mineralized foam. Adjust the height of the shutter and control the liquid level so that the useful foam is scraped off by the scraper. Thereby completing the flotation process of gold mine With a variety of process flows, the rough selection process or the selection process can be selected according to different coal qualities, making the operation more flexible. The clean coal ash can be reduced by 1~2% compared with the conventional flotation machine. The flotation machine produced today changes the traditional process conditions of mineralization and sorting mixing in the flotation process, and implements a segmentation operation to allow the mineralization process to proceed in the turbulent state of the mineralizer, so that the sorting process is It is carried out in a stable flow with less disturbance, thus ensuring an optimal flotation environment.

Introduction to the processes commonly used in gold ore dressing production
Gold ore types depending on its nature, processing methods used are different, but the devices commonly used, is the flotation machine, this requires high precision flotation machine sorting, fine coal of low ash content, high yield, especially It is more advantageous for difficult coal selection. At the same time, according to the different properties, re-election, flotation, amalgamation , cyanidation and recent resin pulping method, carbon slurry adsorption method and heap leaching method are introduced. For some types of ore, a combined gold extraction process is often used.
