In this paper, I will detail the methods of the gold extraction process, including gravity separation, flotation, cyanidation, and amalgamation.. The content of gold in the ore is extremely low. In order to extract gold, we need to crush the large ore rock into small pieces first, grind it, and then use appropriate gold processing methods to separate the gold from the ore, …

Froth Flotation Process

"The single most important method used for the recovery and upgrading of sulfide ores", that's how G. J. Jameson described the froth flotation process in 1992. And it's true: this process, used in several processing industries, is able to selectively separate hydrophobic from hydrophilic materials, by taking advantage of the different categories of hydrophobicity that are …
