Frothers, as defined by flotation operators, are compounds used specifically for creating a flotation froth. However, most collectors used in iron ore processing produce adequate froths. The general types of these frothing collectors include long-chain carboxylates, sulfonates or sulfates, and amines as listed in Table 9.1. In practice the most ...
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.
Finally, an example of gold ore flotation was used to verify the effectiveness of the method. The optimal solution was a gold concentrate grade of 75.46 g/t and a gold recovery rate of 85.98%. ... With the continuous development of science and technology, gold has been widely used in communications, electronics, aviation, medicine, and …
The most widely-used collectors in sulphide mineral flotation are the xanthates or thiocarbonates. These reagents were developed in the 1920's and played a major role in the spread of flotation throughout the world. Hydrocarbon chain length is from: ethyl C2, propyl C3, butyl C4, amyl C5 to hexyl C6. They are classified as Anionic reagents.
