Processes of gold ore separation . The three most commonly used processes for gold ore separation are: gravity separation, flotation and cyanidation. Among them, gravity separation is a commonly used process in placer gold mines, flotation is mostly used in rock gold mines, and cyanidation is suitable for refractory gold ores such as oxide ore and flotation concentrate.

Froth Flotation of Iron Ores - publications.csiro.au. Froth Flotation of Iron Ores Mark Ma CSIRO Process Science and Engineering, Box 312, Clayton, Victoria, 3169, Australia Abstract With the depleting reserves of high-grade iron ore in the world, froth flotation has become increasingly important to process intermediate- and low-grade iron ore in an attempt to meet the rapidly growing demand
Get PriceLime is often used in flotation to increase the alkalinity of the pulp. An alkaline pH increases the volume of the froth (possibly increasing the rate at which mineral is recovered), and depresses pyrite. Frothers such as pine oil and Dowfroth 250 are used to create a froth capable of

Phosphate ore is an important raw material for manufacturing fertilizers and phosphorous chemical products. While most of the phosphate resources cannot be directly treated as feed stock due to the low grade of P2O5 and high content of impurities. In order to obtain a qualified phosphate concentrate, the beneficiation of the low-grade phosphate ore is, hence, of great necessity.
