As to lead ore which equipment used for crushing and how is the crushing ratio

We can supply many lead ore curshers such as lead jaw crusher, lead impact crusher, lead cone crusher, lead mobile crusher and so on. Metallic lead that results from the roasting and blast furnace processes still contains significant contaminants of arsenic, antimony, bismuth, zinc, copper, silver, and gold. Lead ore crushers are used widely in such ore curshing industry. Since the establishment, Hongxing has grown to become the largest crusher and screening equipment dealer in the China. So, if you want some lead ore or other ore mining equipments or crushing machines, you can come to visit Hongxing which must be your good choice.

Lead oxide from the roasting process is reduced in a coke-fired blast furnace.[6] This converts most of the lead to its metallic form. Three 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.

Metallic lead that results from the roasting and blast furnace processes still contains significant contaminants of arsenic, antimony, bismuth, zinc, copper, silver, and gold. The melt is treated in a reverberatory furnace with air, steam, and sulfur, which oxidizes the contaminants except silver, gold, and bismuth. The oxidized contaminants are removed by drossing, where they float to the top and are skimmed off.
