gold separation methods - Xinhai

2015-12-11  Single flotation process is used to separate coarse and middle gold ore. The gold ore is crushed and ground to the pointed particle size. With the grinding equipment, the gold ore is fed to the flotation cell with the sodium carbonate as a modifier and the butyl xanthate and butylamine aerofloat as a collector for separating the useful minerals and gangue minerals by the different hydrophobic of the mineral surface. 02 2. Flotation with Hg used in gold separation

Gold extraction refers to the process of separating gold from gold-bearing ore. The content of gold in nature is low. In order to extract gold, it is usually necessary to first crush and grind the gold ore and use the extraction method to separate gold from the ore. For different gold-bearing ores, the selection of gold extraction process is different. 2019-08-22 16:54:32 Views:1728 【Learn more】
