Assume 2000 short tons of ore were mined, 200 tones were rejected as waste and the tonnage accepted for metallurgical treatment is 1800. Assay for the feed is 4%, for the concentrate is 4.4% and for the waste, 0.4%.© BrainMass Inc. brainmass.com October 10, 2019, 4:04 am ad1c9bdddf
By weight balance,
That is, 2000=1800+200
By the valuable metal balance,
Mass balancing is particularly important in accounting for valuable mineral or metal distributions and the two-product formula is of great use in this respect.
