Bubble flotation of gold and other precious metals silver and copper star recently introduced technique is a new technique is the use of flotation to the noble metal nanoparticles, the principle is that the noble metal particles to adhere to air bubbles mining flotation machine, in such a process, if the larger stone particles floating dressing, it may be used for fine crushing equipment, adding "flotation" in the flotation machine, the bubble noble metal adhesion occurs, so that they tend to repel water, and It rises to the surface of the water and is easily taken away. Bubble flotation precious metal technology is still in the early stage of use in China, but it can be seen from many practical test results that the technology is very suitable for tailings waste rock recycling technology, and the recovery rate is very high, according to statistical results, If the company uses bubble flotation technology to process 100 million tons of ore a year, it will get about 1,000 tons of precious metals, and the prospects are very promising.
