Graphite is soft and easily floatable but it is quite difficult to obtain high purity concentrate at coarse sizes. Chemical treatment can produce high grade concentrate but it is an expensive process. Graphite containing plus 96% fixed carbon (FC) with coarse flakes commands a high price in the international market. Such graphite concentrate containing plus 96% FC …

Reagent Combinations. Alcohol or pine oil frother alone, or with a mineral oil collector such as kerosene, is generally used. Acid or alkali reagents may be necessary to …
Flotation is a crucial stage in the beneficiation process, as it separates the valuable graphite flakes from the unwanted gangue minerals. This process involves the addition of reagents, such as collectors, frothers, and regulators, to create a hydrophobic surface on the graphite particles.
In particular for graphite beneficiation, a multistage grinding and flotation process (can be up to 10 or more stages) is commonly employed ... In addition to improved flotation efficiency, the dosage of reagents also exhibited a substantial reduction for the weathered samples. For example, the dosages of diesel and terpenic oil for the sample ...
Graphite ore generally needs to be beneficiation to increase its fixed carbon content to 90% or even 95% or more to have a high industrial value, because graphite has a good natural flotation, therefore, flotation is the most commonly used beneficiation of graphite.
The contribution of reagent interactions to gold extraction is statistically insignificant. These findings highlight that ammonia pretreatment and ammonia−cyanide leaching are promising approaches for the treatment of gold ores with high copper sulphide content. ... (1999, 2002a, 2002b) developed a membrane-electrolysis cell with graphite ...
