The Ball Mill, B-101, grinds the 0.25" ore until it is in the range of 160 microns. The ore leaving the ball mill is sent to six hydrocyclones that separate the larger particles from the smaller particles. The top stream leaving the cyclone is 75% of the feed into it. This top product is 160 microns or less.
production in the United States was $86.3 billion, an increase of 3% from the revised total of $84 billion in 2018. The estimated value of metals production increased slightly to $28.1 billion. Lower production of some metals was offset by increased values. Byproduct vanadium was produced in Utah for the first time since 2013.
