Flotation Machine Plays an Important Role in Gold Mining

At present, China has discovered 98 kinds of gold minerals and gold-containing minerals, only 47 are common, and only 10 kinds of minerals are directly used in industry. There are nearly 38 kinds of gold-bearing minerals in China. The gold content of gold mines is generally relatively small. Re-election and flotation are commonly used in gold ore dressing methods. Most gold mines in China use the above methods to extract gold. There are great improvements in the selection of gold mining technology and gold mining equipment.

According to the structural state and gold content of gold in minerals, the gold minerals can be divided into three categories: gold minerals, gold-containing minerals, and gold-bearing minerals. The so-called gold independent minerals refer to gold produced in the form of gold minerals and gold-containing minerals. It is the most important form of gold in the natural world and is also the main object of industrial development and utilization. At present, the mainstream gold-picking process is generally broken by a gold ore processing plant crusher, then crushed by a goal mill, and then through a re-election and flotation process, the concentrates and tailings are extracted, followed by chemical methods, and finally smelted.

The product eventually becomes a finished product. The gold ore beneficiation process can be understood as follows: After the first ore is broken, it enters the double-layer vibrating screen and the upper product is broken together with the middle product to perform the second segment crushing. The second segment of the crushing product is returned to the first segment. The product is sieved again. The screened final product is ground through a first ball mill and closed-circuit grinding with a grading mechanism. The grading overflow is graded by a cyclone and enters a second ball mill for regrinding, and then forms a closed-circuit grinding with the cyclone.
