Magnetic and gravity separation tests were carried out on the Medium grade zircon standard (MGZS) to produce a monazite concentrate at Eramet Ideas laboratory. Magnetic separation at 1.5 teslas intensity resulted in the recovery of 94.8% of the monazite from the MGZS. Gravity separation also recovered 76.6% of the monazite from the MGZS.

2020-1-16 Analyses in ICP-OES showed that the concentrate material had 40.4% of iron, while in raw material, it was 7%. Therefore, gravity separation using Wilfley shaking table is seen as an interesting alternative since it reduces the zinc mine tailing, requires less energy and makes possible the material return to process in the steel industry.

2020-11-30 The gravity separation concentrate has ilmenite while the respective tailings have actinolite (Ca 2 (Mg,Fe) 5 Si 8 O 22 (OH) 2; JCPDS 41-1366), hornblende, and quartz. Figure 14b shows the gravity separation for the monazite concentrate. Monazite was separated from quartz and hornblende using gravity separation.

MorePrinciple of Separation. Spiral separation is based on the specific gravity difference present in a feed mineral suite. When fed a dilute pulp mixture of minerals of different specific gravities, the lighter minerals are more readily suspended by the water and attain relatively high tangential velocities so that they climb toward the outer rim of the spiral trough.

mineral processing - mineral processing - Concentration: Concentration involves the separation of valuable minerals from the other raw materials received from the grinding mill. In large-scale operations this is accomplished by taking advantage of the different properties of the minerals to be separated. These properties can be colour (optical sorting), density (gravity separation),
