    Abstract: The present invention relates to a method for separating diamond from gangue minerals. In particular, this method relates to the addition of a first reagent or reagents which contact the diamond in diamond ore slurry to at least partially remove hydrophilic coatings from the diamond surfaces. A second reagent or reagents may also be added to the slurry so that the reagent may adsorb on the diamond surfaces and thereby enhance the hydrophobicity of diamonds. The increase in hydrophobicity may improve the flotation of diamonds.

    Abstract: A derivative of aspartic acid is used as a collector for a phosphate containing mineral, such as apatite, in a froth flotation process. According to the invention the collector has a high selectivity for phosphate containing minerals even in the presence of carbonate minerals, such as calcite. The derivative has the formula (I) where RI is a hydrophobic group containing a hydrocarbon group of 6-24 carbon atoms; RII is an alkyl group with 1-7 carbon atoms or a group of the formula (B)yH, in which B is an alkyleneoxy group with 2-4 carbon atoms and y is a number from 1 to 10; and M is a group selected from the group consisting of a cation or hydrogen. Methods for producing the derivative are also described.

    Abstract: A process for the flotation of non-sulfidic minerals or ores, is disclosed in which crushed crude minerals or ores are mixed with water and a collector to form a suspension, air is introduced into the suspension in the presence of a reagent system, and a floated foam containing the non-sulfidic mineral or ores is formed therein along with a flotation residue comprising the gangue polymeric esterquats as the collector polymeric esterquats. The polymeric esterquats are obtained by reacting alkanolamines with a mixture of monocarboxylic acids and dicarboxylic acids and quaternising the resulting esters, optionally after alkoxylation.
