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. The solubility, pH application range, physical state

Flotation Reagents & Collectors ArrMaz

Collectors, some of the most important flotation reagents used in the flotation process, are used to modify the surface properties of minerals. A collector is a chemical that selectively binds to the surface of target minerals and imparts hydrophobicity to those mineral particles, a necessary condition for air bubble attachment.

Primary biodegradation of sulfide mineral flotation collectors

Sulfide mineral flotation collectors are the most widely used reagents in flotation (Hope et al., 2001). Groundwater pollution due to tailing dams is a worldwide problem. The serious environmental problems associated with flotation reagents in mineral processing plant wastewater have been well documented (Chockalingam et al., 2003).

Introduction to Mineral Processing Chevron Phillips Chemical

Collectors Orfom® CO series collectors. A collector is a chemical that attaches to the mineral surface and produces a hydrophobic (water-fearing) surface. While certain minerals are naturally hydrophobic and do not require a collector, recovery is often improved when a collector is used.

Flotation Reagents Mineral Processing & Metallurgy

Flotation Frothers What is the Function of Frothers. The function of frothers in flotation is that of building the froth which serves as the buoyant medium in the separation of the floatable from the non-floatable minerals. Frothers accomplish this by lowering the surface tension of the liquid which in turn permits air rising through the pulp to accumulate at the surface in bubble form.

Role of Collectors and Depressants in Mineral Flotation: A

A theoretical analysis was conducted to study the role of collectors and depressants in flotation, based on the extended Derjaguin–Landau–Verwey–Overbeek (DLVO) theory, where the hydrophobic force is considered. The collector-coated hydrophilic particle and the depressant-coated hydrophobic particle are simplified to a sphere uniformly covered with respectively hydrophobic and
