Treatment of lead and zinc ores begins with milling. Milling is a multistage crushing and grinding operation. It involves coarse crushing followed by wet grinding. Crushing is usually a dry operation that utilizes water sprays to control dust. Primary crushing is often performed at the mine site, followed by additional crushing at the mill.
Smelting plants that use to purchase considerable amounts of hard rock ore from prospectors have mostly gone away due to the high regulatory costs. While the high cost of extraction may limit the values that can be obtained from certain material, ores that have a considerable amount of free gold may still be mined profitably by the average miner.
