On the principles of preparation of conditions for mica deposits
Authors:
Abstract
The most important indicators of mica deposit conditions are minimum commercial and cutoff grades. Up to now all calculations of mica (phlogopite and muscovite) reserves have been carried out according to Glavsluda conditionals of the USSR Ministry of Railroads, introduced in 1950. For deposits of phlogopite and muscovite these conditions provide the following content of broken mica per minimum excavation thickness of veins, equal to 1 m, kg • cm2/m3.
