2022815 · In the process of reverse flotation separation of magnesite from quartz in the presence of DDA as a collector can cause magnesite to float together with silicon-bearing gangue minerals. Therefore, the development of highly selective collectors for the flotation separation of magnesite and quartz is becoming increasingly more important.

2020101 · Abstract This research focused on the effect of particle size and flotation time on magnesite flotation, and the flotation performance of various size fractions were predicted by a machine learning (ML) method. Four kinetic models were used to fit the recovery of MgO and SiO 2 in various size fractions of magnesite flotation.

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 …

202421 · This inadequacy results in complex on-site processing techniques, low resource utilization, and high energy consumption. Consequently, exploring new flotation agents with high selectivity for magnesite purification holds promising avenue for the efficient utilization of low-grade magnesite resources.

202211 · Abstract In the flotation of magnesite, it is not easy to separate magnesite from calcite. Under this study, Sodium tripolyphosphate (STSP) was considered to be an inhibitor for improving the flotation separation efficiency of magnesite from calcite. Through relevant analysis, such as potentiodynamic potential measurement, infrared spectrum …
