Reverse flotation separation of hematite from quartz Aug 01, 2019 As of today, very little is known about magnetic aggregation in the flotation process of hematite. Therefore, in this work, the effect of selective magnetic aggregation on the flotation of fine hematite from quartz was investigated using simulated pulp with added minerals.

Froth Flotation of Iron Ores Mark Ma CSIRO Process Science and Engineering, Box 312, Clayton, Victoria, 3169, Australia Abstract With the depleting reserves of highgrade iron ore in the world, froth flotation has become increasingly important to process intermediate and lowgrade iron ore in an attempt to meet the rapidly growing demand on the
2011830&ensp·&enspDiamine flotation of quartz 149 Comparison of Figures 1 and 3 with Figures 5, 6, 7 and 8 illustrates the importance of the doubly charged species in promoting flotation. Further, it can be seen that the large increases in flotation at some point with further pH increase appears related to the approach of the amine surface concentration to near surface amine precipitation values.

2018326&ensp·&enspThe effects of Ca2+, Mg2+, Al3+, and Fe3+ on the flotation behaviors of apatite, dolomite and quartz were investigated through a microflotation test, and the influence of calcium ions on the flotation of these minerals was further elucidated by solution chemistry study, zeta potential measurement, and Xray photoelectron spectroscopy (XPS) analyses.
201788&ensp·&enspThe major requirement for the flotation process is the removal of the large amount of quartz in the flotation feeds. For this purpose, depressants are often added to depress the flotation of quartz. Common depressants used in fluorite flotation are water glass, phosphate and some kind of colloid such as tannin and starch [5,6,7]. Of all
