largest mines in eastern Idaho, producing phosphate ore under various mine operators from 1906 through 1984. During open-pit mining, overburden (waste rock) was removed from the mine pits and placed in overburden disposal areas (ODAs). The RI/FS at the Conda/Woodall Mountain Mine began in 2008.
The physical way is low-cost and has little impact on the environment. Firstly, most impurity minerals are sorted out to purify kaolin. 1. Magnetic separation methods. Magnetic separation is the primary physical iron removal method. Iron mineral impurities in kaolin usually have weak magnetic properties and can be removed by magnetic separation.
