Froth flotation is a process for separating minerals from gangue by taking advantage of differences in their hydrophobicity. Hydrophobicity differences between valuable minerals and waste gangue are increased through the use of surfactants and wetting agents. The selective separation of the minerals makes processing complex (that is, mixed) ores economically feasible. The flotation process is used for the separation of a large range of sulfides, carbonates and oxides prior to further refinement. Phosphates and
Other Industrial Minerals. Discovering the true potential of an industrial mineral deposit is no small challenge. ArrMaz’s metallurgical lab has the experience and expertise to test new chemistries on your mineral deposit to help you understand its true value.
“Industrial minerals” is a diverse range of non-sulfide substrates which require an individual approach in order to optimize cost-performance ratio of their beneficiation by flotation. We offer solutions for the flotation of non-sulfide minerals such as Bariyte, Calcite,

For more than a century now, flotation has been at the heart of the mineral processing industry. In this month’s SPOTLIGHT FEATURE ARTICLE, direct from the November issue of INTERNATIONAL MINING magazine, John Chadwick examines new technologies and applications from some of the key players in mineral flotation, a technique that is so important to the global industry.
Description. The “pulp” (i.e. mineral-water slurry after grinding) is commonly passed through a hydrocylone to concentrate the “sands” and reject the “slimes” (the finest size fractions, say 30um), the slimes are objectionable in several respects: they are slow to float, the consume a disproportionate share of the reagents, and they may seriously spoil the selectivity of flotation ...
Flotation Reagents Collectors. Froth flotation is the most widely used industrial process for the separation of finely liberated minerals. The process involves the aeration of minerals in water in the presence of flotation reagents which facilitate the attachment of air bubbles to and levitation of select minerals.

Process engineering for the chemical, metals and minerals industry, Volume 2}, author = {Rubinstein, J B}, abstractNote = {Practically all mined ores of non-ferrous and rare metals and an increasing share of industrial minerals and coal are processed through flotation.
The recovery of these copper minerals by flotation or hydrometallurgy from ores, typically containing 0.5%TCu (open pit mines) and 1-2%TCu (underground mines) is of great commercial importance.
Traditionally, flotation is considered efficient up to about 0.250-mm; however, given the proper equipment and flow sheet, there is an opportunity to conduct flotation at sizes coarser than 0.250-mm and up to and exceeding 1-mm. Igneous deposits can benefit from coarse flotation, but they are also amenable to very fine flotation.

Flotation of semi-soluble salt minerals such as potash, phosphate, fluorite and calcite, is controlled by surface chemistry and therefore the selection of appropriate reagents and conditioning methods drives recovery. Once hydrophobic, the minerals are fast floating making conditions in the Jameson Cell perfect for recovering these minerals.
The process involves the separation of hydrophobic from hydrophyllic minerals. Flotation has now become the most widely used process for extracting minerals from ores. Designing flotation schemes in a laboratory allows you to optimize the process. Minerals require coating with a chemical to make their surface hydrophobic.
