Sulphide Gold Ore Treatment by Leaching and Flotation Process

18/04/2016· The calcine is then quenched, ground and returned to the plant. In fact, flotation has made possible the treating of such ore bodies for the recovery of gold. It was never possible to treat these direct by cyanide and difficult to roast ore alone because of the large amount of extraneous heat required. Flotation concentrates are usually self-roasting. One particular plant uses a flowsheet similar to No. 2. Here flotation

01/11/2011· “Flotation reagent selection is paramount and test work is necessary to ensure the optimum reagent suite is utilised. If the ore contains a low amount of iron sulphides, xanthate collectors are often suitable to float copper sulphideminerals. If native gold is present, dithiophosphates can be used which are less selective to iron sulphides.

Iron ore is the key raw material for steel production enterprises. Generally, iron ore with a grade of less than 50% needs to be processed before smelting and utilization. After crushing, grinding, magnetic separation, flotation, and gravity separation, etc., iron is gradually selected from the natural iron ore.

Froth flotation - Wikipedia

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.
