摘要： The present invention relates to a process for treating non-sulfidic ores with a collector composition containing a primary and a secondary collector, wherein the primary collector is selected from the group of amphoteric and anionic surface active compounds and the secondary collector is an ethoxylated fatty acid wherein the average degree of ethoxylation is higher than 0 and less than 2, to collector compositions suitable for use in the above process, and to pulp comprising such collector compositions.

摘要： The present invention relates to a compound obtainable by the condensation of a polyol having 3-4 hydroxyl groups, adicarboxylic acid or a derivative thereof, an alkanolamine and a fatty acid, followed by reaction with an alkylating agent. This compound is useful as a collector in a process for the reverse froth flotation of non-sulfidic ores containing silicate as impurities, especially phosphate ores.

摘要： The present invention relates to a compound obtainable by reacting an N-acyl neutral amino acid or a salt thereof, or an N-acyl neutral amino acid oligopeptide or a salt thereof with a monohydroxy monocarboxylic acid or a salt thereof. This compound is useful as a collector in a process for froth flotation of non-sulfidic ores, especially phosphate ores. The invention also relates to a method which comprises the steps of a) conditioning a pulped phosphate ore, wherein the phosphate ore comprises a calcium phosphate mineral or a mixture of such minerals, and gangue minerals, with an effective amount of a calcium phosphate mineral collector reagent, which is the above-mentioned compound, and optionally other flotation aids and b) performing a froth flotation process to recover the calcium phosphate mineral(s).
