A tube releases air into the tank of the machine and an agitator creates air bubbles at the bottom of the tank. Minerals that are hydrophilic, such as gold, attach to the bubbles’ surface and are brought up to the top of the tank.
12.3 Primary Copper Smelting
Copper ore is produced in 13 states. In 1989, Arizona produced 60 percent of the total U. S. ore. Fourteen domestic mines accounted for more than 95 percent of the 1.45 megagrams (Mg) (1.6 millon tons) of ore produced in 1991. Copper is produced in the U. S. primarily by pyrometallurgical smelting methods.Special Wastes | US EPA,Jul 06, 2021· Beneficiation follows and is the initial attempt at liberating and concentrating the valuable mineral from the extracted ore.
