Bentonite is a raw material present in many countries and mined in open pit quarries. Bentonite deposits are most often quite large, with lenticular beds, only a few meters deep. Bentonite production process features ore mining, sodium activation – if required -, drying, and milling. Sodium activation is performed to convert calcium bentonite to sodium bentonite, in which calcium ions are exchanged for sodium carbonate.

Wyoming is also home to the nation's largest volume of recoverable uranium, a critical mineral, There are almost a dozen authorized uranium mines across the state, which predominantly use in-situ recovery instead of open pit mining. In-situ recovery minimizes disturbance by extracting dissolved uranium ions without impairing the surface estate.

Mar 01, 2017 · In open pit blasting, to utilize the kinetic energy and improve fragmentation, part of muck pile from previous blast should be left in front of new bench face. In this case, when next blast happens, the fragments from the first row will collide with the muck pile left from the previous blast.
