Flotation of Dolomite from Apatite

Jun 29, 2018 The flotation process lasted 3 min for each test. Following this, the flotation recoveries were calculated based on the weights of concentrates and tailings. For artificial mixed minerals flotation experiments, the mass ratio of apatite and dolomite mineral was 1:1 for binary mixture. The flotation process was the same as single mineral tests

Flotation separation of dolomite from fluorapatite using

Aug 02, 2021 For the reverse flotation of phosphate ore, a high amount of sulfuric acid is required. In this study, we used NaF as a flotation activator to separate dolomite and fluorapatite to reduce acid consumption in the flotation process. Both single and actual mineral flotations were conducted.

Comparative analysis of dolomite/francolite flotation

Aug 01, 1996 The results of bench-scale testing of five flotation processes for the separation of dolomite from phosphate are discussed. Each process is compared in terms of phosphate recovery, MgO content of the concentrate and reagent consumption. Water quality was found to play a major role in the performance of these processes. The effect of water hardness, in addition to other parameters,

Dolomite flotation was attributed to hydrogen bonding of oleic acid on dolomite in addition to CO2 gas evolution. In an effort to develop new reagents that interact selectively, Eu and Somasundaran (1986) used alizarin red S, a dye that stains calcite, and achieved effective separation of calcite from apatite with sodium oleate as the collector.
