Recovery of Chromium from Surface-finishing Wastes.
MISSING :8 pages
The Bureau of Mines has demonstrated a hydrometallurgical method to separate chromium from other metals in a variety of surface- finishing wastes by precipitation with benzoate ion. The resulting chromium salt may then be converted to the hydroxide, and the benzoate may be recycled. Chromium recoveries of 92 to 100 pct are obtained.
