AP42 12.18 Leadbearing Ore Crushing and Grinding

2015-9-10  Lead ores from Missouri mines are primarily associated with zinc and copper. Average grades of metal from Missouri mines have been reported as high as 12.2 percent lead, 1 percent zinc, and 0.6 percent copper. Due to ore body formations, lead and zinc ores are normally deep-mined (underground), whereas copper ores are mined in open pits.

The ground ore is mixed with water to form slurry which chemical reagents are added, and then aerated to produce bubbles. Using the principle that the hydrophobic ore particles attach to the bubbles, the target ores are recovered. From this process, copper concentrates with 20-40 %-Cu is produced, which is sent to a smelting and refining plant ...
