The adsorption mechanism of collector mixtures and the implication for mineral flotation are discussed in light of the results of a quantitative study of the flotation of fluorapatite and calcite with mixtures of fatty alcohol and oleate collectors.

Refereed/Peer-reviewed Water quality affects the flotation recovery of minerals and their separation. Mining-process waters become saturated with soluble salts after contact with minerals (oxidation and dissolution) during crushing, classification an

In the reverse anionic flotation of phosphate ores using phosphoric acid, it is often suggested that a selective surface passivation of the phosphate minerals by calcium phosphate occurs. Several calcium phosphate species have been proposed in the li

Literature shows that flotation is highly size dependent and processing both coarse and fine size fractions is problematic. The latter is the subject of the current paper. Fine particles have a relatively high surface area, and therefore more reagent

The objective of this study is to relate the flotation of coarse composite particles with their mineral composition. For this purpose, composites of quartz particles in lead borate matrix were fabricated in different size fractions. The quartz in the

Nickel is an important metal globally with a consumption of about 2 million tons per year. This is supplied from both sulfide and laterite ores, but currently laterites are becoming more attractive for nickel production due to the depletion of high g

Nickel is sourced from sulphide and laterite ores. While 70% of the nickel resources are contained in laterites, these ores are often complex and expensive to treat using conventional methods. Therefore, upgrading the nickel content in laterite ores

The separation between calcium minerals such as apatite and calcite by flotation relies on the use of long chain fatty acid collectors. Oleic acid, and its salt, is the main fatty acid collector and many studies have reported on the mechanisms of its
