Lead Ore Grinding Mills Lead Ore Grinding Mills

The lead ore occurs in two types of deposit: as primary lead ore in thin veins known as rakes, or a secondary deposit formed by weathering of the primary lead veins. In our modern life, the majority of the lead consumed annually is used to make batteries for cars, trucks and other vehicles, as well as wheel weights, solder, bearings and other parts. No matter investors adopt any mining method, grinding is necessary step. Of course, in the leading mining industry, the grinding stage is necessary, using a grinding mill to produce lead ore particles into a certain size. Here we focus on more details of XSM’s lead ore grinding mills, also called lead ore grinding machine by customers.

Outlook Of Lead Mining Industry

Today, the production and consumption of lead is increasing worldwide. Total annual production is about 8 million tonnes; about half is produced from recycled scrap. According to statistical figures, the top lead producing countries are Australia, China, USA, Peru, Canada, Mexico, Sweden, Morocco, and South Africa. At current use rates, the supply of lead is estimated to run out in 42 years. Many environmental analysts have suggested lead could run out within 18 years based on an extrapolation of 2% growth per year. This may need to be reviewed to take account of renewed interest in recycling, and rapid progress in fuel cell technology. As for lead investors, they can adopt high-efficiency mining machienry to improve the mining efficiency and save more lead ores. Therefore, the use of advanced mining machinery should arouse the attention of lead mining investors.

Brief Introduction Of Lead Mining Flowchart

Lead mining can be considered as a comprehensive project, including different mining stages.

Most ores contain less than 10% lead, and ores containing as little as 3% lead can be economically exploited. Lead ores should be crushed and grinded, and then they are concentrated by froth flotation typically to 70% or more. Sulfide ores are roasted, producing primarily lead oxide and a mixture of sulfates and silicates of lead and other metals contained in the ore. Lead oxide from the roasting process is reduced in a coke-fired blast furnace to the metal. Additional layers separate in the process and float to the top of the metallic lead. These are slag (silicates containing 1.5% lead), matte (sulfides containing 15% lead), and speiss (arsenides of iron and copper). These wastes contain concentrations of copper, zinc, cadmium, and bismuth that can be recovered economically, as can their content of unreduced lead.

Lead Ore Grinding Mill

Lead ore grinding mill refers to the grinding machine specially used for grinding lead ore particles into smaller ones. As for the selection of lead ore grinding mill, engineers from XSM suggest our LM Series vertical mill, which can crush, dry, grind, and classify the materials into one set. As a lead ore grinding mill, it can be installed outside, so it will reduce a large number of investment costs. It is equipped with system of automatic control, so remote control makes it easy to operate. As the material stays in the mill for a short time, LM Series vertical mill is easy to detect and control the product particle size and chemical composition, to reduce duplication of milling, stable product quality. The capacity of LM Series vertical mill ranges from 10 to 128 tph. The output size of final product ranges from 80 to 325 mesh.
