Gold ore has good physical and mechanical properties, corrosion resistance and high chemical stability. Its application is very extensive. Gold ore has golden color and processing performance, it has always been used to make jewel and ornaments from the ancient times. Gold ore has very high chemical stability and it is regarded as a kind of metal currency. It is still the important international currency. The gold reserve is regarded as one of the important marks to measure a country’s ability to pay and economic power.
Flotation machine is widely used in the extraction process of gold ore. Sometimes experts call the flotation machine for flotator in short. Typically, flotation machine is used in the benefication process. When it works, gold slurry is fully mixed with potions, and stirred powerfully to make air enter it. Some mineral particles float on the froth because of low density. The rest sink down, paving the way for later separation. The flotation machine adopts the principle of gravity separation. Here we focus on more details of flotation machine for gold mining.
The impellers are driven through V-belt transmission, which brings centrifugal effect to form the negative pressure. On the one hand, the flotation machine inhales sufficient air to mix with the ore slurry; on the other hand it stirs ore slurry and mix with potions to form the mineralized froth. And then operators should adjust the height of flashboard to control the liquid level and scrape the useful forth by loam board. After the mineralized froths gather more and more, the loam board scrapes them and they turn into clean coal foams. With the rotor moving slow, the selected particles are distributed into the 6 sorting rooms through the slurry distribution device.
