Mineral Commodity Summaries 2022
Events, Trends, and Issues: During 2021, estimated domestic production of crude garnet concentrates decreased by 26% compared with production in 2020. This decrease was due to lower production levels from a mine in Montana, although most other U.S. garnet mines also produced less compared with that in 2020.

Sol-gel synthesis of yttrium aluminum garnet (YAG): effects of the
Abstract The sol–gel synthesis of yttrium aluminum garnet (YAG) was performed using different metal precursors (salts and alkoxides of aluminum and yttrium) and metal concentrations (up to a concentration factor of 7.4). The cross-reactivity of the aluminum and yttrium precursors is not clear, and generally, the sol–gel process leads to …

Gravity Separation
To determine the suitability of gravity separation processes to a particular ore type, a concentration criterion is commonly used. A concentration criterion (CC) can be defined as [1] (16.1) Concentration Criterion = SG of heavy mineral − SG of fluid SG of light mineral − SG of fluid where SG = specific gravity (or density), and the fluid ...
