The primary reason for the significant comminution circuits is because in gold mining the grades are notably low and thus excessive waste material is present, resulting in high mill feed rates. If the ore rock is highly fractured and/or brittle, it is likely that an AG mill …
Jan 01, 2016 · 1. Background. The application of flotation on a reasonable scale within the gold-mining industry commenced in the early 1930s following the introduction of water-soluble flotation collectors (specifically xanthates and dithiophosphate collectors) that allowed differential flotation of sulfide minerals (Weinig and Carpenter, 1937, Rabone, 1939, Richards and Locke, 1940, Taggart, 1945)
The flotation concentrates can be sold to the smelting factory based on normal trade or processing agreement. The flotation concentrates go to cyanide process or calcination process (if there is arsenic together with the concentrate) and further process to get pure gold in the smelting factory

In ore benefication plant, one important rule is to crush more and grind less
Feb 06, 2018 · Pre-19th century placer mining operations used mercury to dissolve the gold in crushed ore, making it easier to recover. Later innovations include the MacArthur-Forrest Process and borax flux extraction. However, one of the most interesting methods is froth flotation. Froth flotation works by exploiting the hydrophobic properties of gold molecules
4 Types of Gold Ore Froth Flotation Combined Process. The common gold extraction processes include gravity separation process, froth flotation process, cyanidation, etc. Froth flotation process is the most widely used in gold extraction, but for different types of gold, we can choose flotation process combined process in order to improve the return on investment
Aug 01, 1999 · Flotation test work indicated that sodium naphthalene sulfonate was the most suitable depressant reagent for carbon and revealed that optimum reagents levels were between 250 g/t and 275 g/t SNS. Higher levels resulted in depression of the gold bearing sulfide minerals and subsequent decreases in gold recovery during flotation
