[Process Introduction] Crushing and Screening. Many alluvial gold ores contain cementing mud pie and most of its particle size is over 100 mm, which will be excluded together with waste rock in the process of screening if not being crushed, thus is a loss of gold Vibrating screen and trommel are the commonly used screening equipment, which has long service life and high processing capacity
Mar 09, 2010 Ore feed to the plant comprises predominantly eluvial soils with a high clay content, and containing between 10 and 20% Cr2O3. Complete dissemination of the clay is required in order to liberate the chromite grains, which lie mostly in the particle range 50-250 microns
