Milling / Screening – Just Refiners (USA) Inc:
Milling: Particular care is taken when processing furnace linings, graphite crucibles and borax slag containing metallic gold and silver. Not only do we homogenize the byproduct materials by crushing to reduce the particle size to less than 10 mm (1/2 inch) in size for sampling purposes, we proceed to feed the crushed materials through a rubber lined, vibratory, ball mill.
