Comparative studies on phosphate ore flotation collectors

Comparative studies on phosphate ore flotation collectors

May 01, 2018 The unsaturated fatty acids content in the JZQ-FO collector is only 27.43%. The JZQ-FO collector contains more saturated fatty acids which were mainly palmitic and stearic acids. These results support that the flotation effect of the JZQ-FB, JZQ-FQ, and JZQ-FDG collectors is more effective relative to the JZQ-FO collector for phosphate ore ...

Flotation features of fluorapatite with ricinoleic acid

Jan 04, 2021 Improving the collecting ability of a collector is a crucial issue in phosphate flotation. In this work, ricinoleic acid (RA) was used as a collector for fluorapatite (FA, Ca5(PO4)3F) flotation. There is an OH group in the middle of the RA molecule, and thus, hydrogen bonds (H-bonds) can be formed between RA species. The role of the H-bond between RA molecules in FA flotation was revealed by ...
