A dry magnetic separation technique was used to separate dolomite from magnesite. The magnetic separation of the sample resulted in a magnesite concentrate product assaying

Selective Flocculation Enhanced Magnetic Separation of

Simple magnetic separation for a certain magnetite mine with ultrafine disseminated lean ores has resulted in low performance, as the fine sizes and aggregation of ground mineral particles have caused inefficient recovery of the ultrafine minerals. In this study, we attempt to increase the apparent sizes of target mineral particles, and improve the separation indices, by using a multi-stage

2018-1-15  Fig. 8 also shows that the recovery of dolomite decreases from pH 4 (40%), to 7 (16%) to 10 (8%). For monazite, the maximum floatability was achieved at pH 7. The amount of floated monazite was 6%, 32% and 10% at pH 4, 7 and 10, respectively, comparable to flotation with benzohydroxamic acid.

2021-8-20  The floatability of magnesite, dolomite and quartz is a major factor affecting the removal of silicon and calcium from magnesite ore. The effect of the regulators sodium hexametaphosphate (SH

Pre-concentration of fluorite from a rare earth element

2021-6-12  During magnetic separation, maximum separation efficiency was obtained with three sequential passes at a magnetic intensity of 5,000 Gauss. During leaching, the optimum conditions were an HCl solution concentration of 5 M, a leaching time of 60 min, a reaction temperature of 20 °C, and an S/L ratio of 25% (w/v).

A Review of Flotation Separation of Mg Carbonates

It is well documented that flotation has high economic viability for the beneficiation of valuable minerals when their main ore bodies contain magnesium (Mg) carbonates such as dolomite and magnesite. Flotation separation of Mg carbonates from their associated valuable minerals (AVMs) presents several challenges, and Mg carbonates have high levels of adverse effects on separation

The isoelectric point (IEP) of pure dolomite was located at pH 6.0–7.0, while that of apatite was at pH 3.0–4.0. It revealed that the optimal pH range for the separation of dolomite and apatite was between pH of 3.0–7.0, which was consistent with that of previous studies,.
