A New Approach to Selectively Reject Naturally Hydrophobic
Efficient separation of naturally hydrophobic gangue, such as talc and carbonaceous materials, from sulphide minerals in flotation is becoming a significant challenge in many processing plants due to the need to process lower grade and more complex ores. Considering the hydrophobic nature of these gangue minerals, prefloating …

Enhanced inhibition of talc flotation using acidified sodium silicate
The flotation separation of chalcopyrite and talc is challenging due to their similar natural floatability characteristics. Besides, it is usually difficult to effectively inhibit talc by adding sodium carboxymethyl cellulose (CMC) alone during chalcopyrite flotation. Here, a combined inhibitor comprising acidified sodium silicate (ASS) and CMC was …

Pyrite recovery mechanisms in coal flotation
Pyrite recovery mechanisms in coal flotation. In most operating coal-cleaning plants, a significant amount of pyrite is recovered in the froth during flotation of high-sulfur coal. This pyrite recovery is commonly believed to be a result of pyrite particles floating due to hydrophobicity. However, even though a wide range of pyrite depressants ...

The Importance of pH in Flotation. In flotation, pH control is a vital method to control selective mineral separation. A standard depressant that is used is an Alkali. An Alkali is any substance that when mixed with Acid will neutralize each other and form a new chemical substance called a BASE. This is very important.

The rate of increase became very slow after 3 min, and the recovery increased by only 5% in 3–10 min. At the same time, when the flotation time is within 10 min, the recovery of talc is always less than 10%. Therefore, for the reagent system of this work, 3 min is the most efficient and preferred flotation time.
