Electrolyte Control at Chinchpada Refinery is a document available to read on EtoBox.
This technical paper discusses electrolyte impurity control practices at Sterlite Industries copper refinery in India. The refinery processes anodes with varying impurity levels, especially bismuth from 10-150 ppm. To control impurities like bismuth and antimony, the refinery progressively increases arsenic levels in the electrolyte, causing the bismuth and antimony to report to anode slime instead of dissolving. Nickel and iron contents are controlled using a novel low-cost acid purification system that re
