The Methodology of Use of the Mobile Crushing-and-Sorting ...

This paper justifies the use of the mobile crushing-and-sorting radiometric complexes (MCSRC) under conditions of iron-ore pits in order to increase the ore quality produced in the mine faces of the «ore-rock» contact zone and stabilize the content of the useful component in the general ore-flow. The patterns, which are used as a fundamental base of the radiometric sorting process, are given.
