ABSTRACT:
In the beneficiation of phosphate ore by the flotation of siliceous material, the utilization of a condensate of N-aminoethylpiperazine with a fatty acid or fatty acid ester improves the separation of phosphate from silica. This improvement is especially great in the presence of a co-collector consisting of a polyethylenepolyamine condensed with a fatty acid.
