Talc Compressive Strength
Characterization and processing of talc-magnesite from the Zinelbulak
The parameters of density, open porosity, water adsorption, compressive strength and refractoriness were determined following ASTM standard methods [5-7] . The talc-magnesite rocks were sequentially crushed in jaw and roll crushers and then pulverized by means of a ball mill. The particle size was thereby reduced to nearly 2.5 mm.
