Embodiment

[0019] The reagent blends of the present invention were tested using Sylfat FA2 fatty acid collector. The following are the results of this test.

[0020] FA2 has a cloud point of about 14°C due to its saturated fat content. Fats consist of fatty acids and glycerol; those with one or more double bonds in the carbon-carbon linkage are called unsaturated fatty acids and examples include oleic acid, linoleic acid, and linolenic acid. Sylfat FA2 is tall oil fatty acid (TOFA), which is a combination of relatively high unsaturation (C18) and carboxyl (-COOH) acid functionality.

[0021] The cloud point of the fatty acid mixture decreased slowly with the increase of unsaturated fatty acid content. If the crystal growth is inhibited when the fat is cooled, its cold resistance can be improved. If one could find a chemical that dissolves the saturated component that first crystallizes from the fatty acid on cooling and that itself has a very low freezing point, it would lower the fre...

Abstract

A novel reagent blend and a method by which a fatty acid collector can be used at temperatures below which the fatty acid normally begins to solidify. The reagent blend may comprise fatty acid, an emulsifying reagent, and glycol ether. The emulsifying reagent may comprise 5% of the reagent blend, while the glycol ether may comprise 1% of the reagent blend. The reagent blend may be used for mineral flotation without the addition of heat.

Description

[0001] cross reference [0002] This application is based on and claims priority from US Provisional Patent Application Serial No. 63 / 011,952, filed April 17, 2020, which is incorporated herein by reference in its entirety. technical field [0003] The present invention relates generally to mineral flotation, and more particularly, but not by way of limitation, to novel reagent blends and methods whereby a fatty acid collector can be condensed at a temperature below which it normally begins to solidify. temperature. Background technique [0004] Many non-metallic mineral flotation plants rely on the use of fatty acids to render the desired mineral hydrophobic. Many processes rely on some form of heat during conditioning because mineral collector attachment occurs more efficiently at elevated temperatures at least above the temperature at which the fatty acids begin to solidify. [0005] In cold water flotation of non-metallic minerals, as the temperature of the process wa...
