Review of the Main Factors Affecting the Flotation of

The way to successfully upgrade a phosphate ore is based on the full understanding of its mineralogy, minerals surface properties, minerals distribution and liberation. The conception of a treatment process consists of choosing the proper operations with an adequate succession depending on the ore properties. Usually, froth flotation takes place in phosphate enrichment processes, since it is

Selective depression behavior of guar gum on talc

The depression behavior and mechanism of guar gum on talc-type scheelite flotation were systematically investigated by flotation experiments, adsorption tests, zeta-potential measurements, and infrared spectroscopic analyses. The flotation results for monominerals, mixed minerals, and actual mineral samples indicated that guar gum exhibited much higher selective depression for talc than for

Use of depressants in the direct flotation of a silicate

2021-2-20  1. Introduction. Flotation is the most common concentration process used by the mineral industry, both in quantity of ores processed and in diversity of applications (Peres et al, 2007).At present, over 2 x 10 9 t per year of ore is estimated to be processed through flotation. In Brazil, this technique played an important role in the growth of the mineral sector, especially in the industry of

apatite and calcite separation by flotation

Carbonate Phosphate Separation by Flotation. Selective fatty acid flotation of carbonate gangue from sedimentary apatites was achieved under acidic pH’s without a specific apatite depressant and without conditioning the pulp with the collector. Concentrates (3538% P2O5, % MgO) with high recoveries (8085%) were produced from Indian and Chinese

Froth Flotation of Iron Ores Publications

the most popular flotation route in iron ore industry, the direct flotation of iron ox ides still appears desirable for some low grade iron ores that contain a vast amount of quartz. For example, at Republic Mine, Michigan, U.S.A., a hematite ore is upgraded from 36.5% Fe to 65.4% Fe with a Fe recovery of 82.5% using the direct flotation route.
