DMS ( dense medium separation) is an efficient and widely used technique, especially useful for separating valuable minerals with relatively high gangue densities. It is often used in the processing of diamond, coal and various base metal ores.
And particles transformed from dense to a porous honeycomb structure. Therefore, the mineral phase transformation achieves recovering iron resources during reducing hazardous waste. It proposed a new way of resource utilization of laterite nickel ore acid-leaching tailings which has positive environmental and resource benefits.
Dry magnetic separation (DMS) has low selectivity for fine magnetic ores, due to the difficult dispersion of fine particles in the separation process. To address this problem, a novel centrifugal dry magnetic separation (cDMS) method was proposed to enhance the separation efficiency for fine particles. In this investigation, the cDMS …
The recovery of fine iron ore by magnetic separation will decrease with decreasing particle size because the magnetic susceptibility of magnetic particles decreases with a decrease in particle mass.
