Mindful of Mining Towns Before mechanization, underground miners used mules to haul the ore out of the Copper Queen mine. Two of Arizona's more famous mining towns, Bisbee and Tombstone, offer underground trips for folks anxious to get a glimpse at what doughty miners did to earn living. Bisbee was, at one time, the greatest copper camp in ...
The extraction process typically involves several steps, including mining, concentration, and smelting. Mining involves the extraction of antimony-rich ore from underground or open pit mines. Once mined, the ore is then concentrated using techniques like gravity separation or flotation to increase its antimony content.
Underground mining is used when the copper ore is not near the earth's surface. Miners dig a shaft into the ore deposit vertically or a horizontal tunnel (or adit) in order to do this. Mining then follows the vein of ore and the …
The stoping method may affect the percentage of ore minerals recovered in the ore-dressing plant, especially where certain sulfide ores are concentrated by flotation. Thus, a stoping method that permits immediate removal of the ore after it is broken so as to preclude its partial oxidation before it goes to the mill may be desirable or necessary.
