Mining Chemicals Division ... with and can be mixed directly with fatty amine and fatty acid collectors and commercial frothers. High flash points and modified pour points contribute to better operational safety and efficient flotation over a wide range of operating temperatures.
The main reason is that the traditional fatty acid collectors not only float the calcium mineral apatite but also the other calcium minerals, calcite and dolomite. We have made a breakthrough in this area and are the only company that can offer collectors that only float apatite without any need for depressant. Flotation of potash
With over 30 years of experience in phosphate flotation, we have developed boosters as well as customized collectors where the traditional fatty acids are not working optimally for direct flotation. We are one of the world''s leading producers of cationic, anionic and non ionic surfactants, which are used in a variety of industries.
principal chemicals used by the mining industry In froth flotation. Among the collectors, we evaluate xanthates, tall 011 derived fatty acid mixtures, and tallow based primary fatty amines.

chemically, what makes one fatty acid a good collector and another one poor?(2) what chemical tests can be runto improve reagent quality? (3) what roles do feed characteristics play? (4) what roles does water quality play? and (5) what are the major physical parameters of fatty acid collectors that influence flotation performance?
Fatty Acid Collectors In 1939 Keck (10), through a series of flotation tests in basic solutions, proved that sodium oleate was a flotation reagent superior to other fatty acids such as ammonium palmolate, ammonium limoleate and potassium myrestate in basic solutions. • • •

Patrick Zhang, Research Director Beneficiation Mining Fatty acid flotation is the key step in phosphate beneficiation, and has significant impacts on both the operational cost and product grade. The Bone Valley phosphate deposit has been very amenable to fatty acid flotation, and is indeed one of the easiesttofloat phosphates in the world.
The flotation separation on chlorite and hematite with the new modified fatty acid collector CY23 was studied. The investigation included both flotation and reagent adsorption tests. And all the characteristics of chlorite surface before and after the adsorption of new collector CY23 have been studied with Xray photoelectron spectroscopy (XPS).

Simply said; a Flotation Collectors is a chemical used to make the surface of minerals, which is metallic, hydrophobic or in layman''s term ''afraid of water'' or ''water hating'' as others like to say. This chemical used will behaved, in a way, as a wax would when you applied it to your car. After wax (or hydrophobic agent) is adhered to the surface, that surface with see water pearlaway.

Tall Oil Fatty Acid (TOFA) CAS#, also known as "liquid rosin" or tallol, is a low cost, viscous yellowblack odorous liquid chemical compound that is a product of crude tall oil vacuum distillation. It is a member of the product family Oleic Acid. Tall oil fatty acids are sold in markets that use them in raw form and as precursors to synthesize an array of products.
