The order of these groups is no indication of their relative importance; and it is common for some reagents to fall into more than one group.Read More

US5720873A Method of floating calcium carbonate ore and

A method of cleaning calcium carbonate ore containing silicate impurities which comprises subjecting said ore to a froth flotation process in the presence of a cationic collector, wherein the collector is a combination of a quaternary ammonium compound having the formula ##STR3## wherein one or two of the group R 1, R 2, R 3 and R 4 are selected from a hydrocarbon group having 8 36 carbon atoms and

Role of sodium carbonate in scheelite flotation A multi

Even though sodium carbonate is a reagent frequently used in flotation, its role is mostly described as a buffering pH modifier and a pulp dispersant. In the case of scheelite flotation, literature has shown that sodium carbonate improves flotation performance but little is

Flotation Reagents Collectors ArrMaz

Flotation Reagents Collectors. 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. Once at the surface, the select minerals are supported by a froth layer until they are removed. Unattached materials remain submerged in the pulp.

Flotation Collectors Mineral Processing Metallurgy

What is a Flotation Collector. For industrial sulfide mineral flotation, the xanthates and dithiophosphates are the major classes of Flotation Collectors compounds used, where M+ is either Na+ or K+, and R is a relatively short hydrocarbon chain typically containing two to five carbon atoms.
