摘要

abstract process for the enrichment of a mineral from silicate-containing ore; method for modifying foam in a process for enriching a mineral from silicate-containing ore; method for increasing the performance of a flotation process for the enrichment of a mineral from silicate containing ore; and Method for Simultaneously Modifying Foam and Increasing the Performance of a Flotation Process for the Enrichment of a Mineral from a Silicate Containing Ore The present invention relates to a method for the flotation of ore silicates in the presence of a collecting agent. and an effective amount of a modifier / foam collector enhancer comprising at least one of the compounds of general formula i or mixtures thereof: r- [n- (ch2) n] mn (x) 2 (i) | r 'where x is C1 -C3 alkyl; R 'is a straight or branched hydrocarbyl group containing from 8 to 22 carbon atoms; n is an integer between 2-4; m can range from 0 to 2 and r 'is x or - (ch2) n-n (x) 2, provided that when r' is - (ch2) n-n (x) 2, then m will be 1.
