crushing and milling lead ores

Lead and Zinc - Energy

2013-11-8  Treatment of lead and zinc ores begins with milling. Milling is a multi-stage 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.

25.3 Crushing and milling Mining of mineral resources ...

A ball mill. Inside a ball mill, the balls move round in a circle as the mill turns, crushing the ore into a powder. This process of reducing the size of the rocks requires a lot of energy. Just image how hard it is to break a rock. How much more energy do you think is needed to crush a rock until it is like sand?

BACKGROUND REPORT AP-42 SECTION 12.18 LEAD

2015-9-10  Lead-bearing ore is mined from underground or open pit mines. After extraction, the ore is processed by crushing, screening and milling. Domestic lead mine production for 1991 totaled 480,000 megagrams (530,000 tons) of lead in ore concentrates, a decrease of some 15,000 megagrams (16,500 tons) from 1990 production.
