The first experiments on the gold flotation from the whole ore were carried out in 1934, it was reported it could be concentrated into a pyritic fraction that was only 2 percent of the mass. The process was applied at Government Gold Mining Areas in 1935.but With the development of science and technology,there are more new ways of flotations technology have been found by people ,now I will tell you more efficiency ways about gold flotation. First:Flotation production line of xinhai  Flotation production line is a common beneficiation technology. It is widely used in gold mines, silver mines, copper mines and lead and zinc mines. In addition, the flotation production line can also be used in nonmetal beneficiation. The followings are detail introduction.

Flotation process maximizes the enrichment of gold into sulfide minerals. The tailings can be directly discharged. Flotation in gold mine has low beneficiation cost  Click here to get more> Last one: Gold CIP Production Line  Gold CIP Production Line adsorbs gold from cyaniding pulp by active carbon including 7 steps: leaching pulp preparation, cyaniding leaching, carbon adsorption, gold loaded carbon desorption, pregnant solution electrodeposit, carbon regeneration, leaching pulp.
