For example, weak magnetic separation is used to separate ilmenite from monazite in seashore placer, or high magnetic separation is used to separate monazite from zircon, quartz and other minerals. In flotation of rare earth ores, in order to simplify flotation process and save flotation reagents, high intensity magnetic separation technology ...
11/95 Sand And Gravel Processing Sand And Gravel Processing Process Description16 Deposits of sand and gravel, the unconsolidated granular materials resulting from the natural disintegration of rock or stone, are generally found in nearsurface alluvial deposits and in subterranean and subaqueous beds.
1 Wash, filter and grind the granite ore with into smaller pieces. 2 Put the ground ore into a tank containing a dilute cyanide solution and add zinc.

1 Answer. mixtures can be separated using various separation methods such filtration,separating funnel,sublimation,simple distillation and paper chromatography. The methods stated above are all physical methods. There are also chemical methods, which are used by rearranging the particles so a certain substance no longer exists (chemical reaction).
In the wet treatment stage, gangue minerals such as quartz, feldspar and mica are removed by gravity separation equipment such as cone concentrator, spiral concentrator, shaker or jig.
