An Introduction To Wet Flotation Machine

The flotation machine is essential flotation equipment in the modern beneficiation process

, which is used to select copper, manganese, silver, gold and antimony ore by flotation. We have the SF series flotation cell and XJK series flotation machine for different ore productionsused to sort gold and silver ore

The flotation machine is the most effective metal equipment to sort gold and silver ore. After grinded, the gold ore and silver ore will be added to water as well as necessary medicament, and infused into a stirring pulp tank. Then importing air to the slurry to form a large number of bubbles, some that not easy to be wetted by water, commonly referred to as the hydrophobic mineral particles will attach to bubbles and float to the slurry surface, forming mineralized bubbles layer; others that easily wetted by water, generally referred to as hydrophilic mineral particles will remain in the pulp and discharge mineralized bubbles which contain specific minerals so as to achieve the purpose of beneficiation.

Hongxing Mining Company adopts the stage-wet grinding magnetic separation process, it uses two to one grinding process with two one-stage ball mill against one one-stage ball mill. Grinding and wet magnetic separating the crude concentrate of 25% grade, finally we can get 66.00% grade iron ore concentrate.

In 2004, Hongxing Mining Machinery Company carried out a research into the high-pressure roller semi-industrial test as well as the sorting test of the rolling mill products. Conducting the discarding tailings of the magnetic pre-selection for the 3to 0mm products with 26.27% grade, thus the qualified tailings of 47.80% productivity and 8310/e grade can be pre-discarded. We can say that this research has opened up a fresh new situation for the utilization of the ultra-poor iron ore in our country. In order to realize the pre-selection discarding of tailings of the ores, promote the grinding grade largely, improve the ore processing capacity at the same time and reduce the grinding and selection operation cost.

Large air-absorption capacity and low energy consumption are the advantages of the floatation machine. Every cell owns three functions: air absorption, slurry absorption, and floatation separation, and the cells form a floatation separation loop by itself without any auxiliary equipment, and is allocated horizontally, which favors the change of flow. The circulation of mineral slurry is reasonable, and can avoid the disposition of coarse sand to the largest extent. There is self-control device on the surface of mineral slurry, so it is easy to adjust it. The impeller has backward-inclined upper and lower vanes, which produce upper and lower circulation of mineral slurrry respectively.
