Therefore the leaching is considerably more expensive than traditional methods of ore processing (ore enrichment). The using of traditional ore enrichment before leaching dramatically reduces the cost of leaching.

Processes that Concentrate Mineral Resources. The concentration of some of the metals comes from the fact that their ions are heavier and tend to sink to the bottom of the molten magma. Later in the process of magma cooling, water and some of the more volatile elements that are not included in the earlier crystallation processes become more.
The International Journal of Mineral Processing covers aspects of the processing of mineral resources such as: Metallic and non-metallic ores, coals, and secondary resources. Topics dealt with include: Geometallurgy, comminution, sizing, classification (in air and water), gravity concentration, flotation, electric and magnetic separation .
Even with its long history the mechanisms of gravity concentration are imperfectly understood, which is partially the reason that the range of equipment available to the gravity concentration engineer is larger than all other branches of mineral processing put together.
ANZAPLAN is not restricted to the above mentioned REE ore minerals but has a proven history in the development of processing concepts adapted to specific REE mineral assemblages including the concentration and hydrometallurgical REE extraction from less well known REE bearing pay minerals such as apatite, eudialyte, allanite, zircon, euxenite .
