Lead Ore Extraction Plant Flow Chart
In lead ore extraction plant flow chart, the first step in obtaining lead-bearing ore is to mine it underground. Workers using heavy machinery drill the rock from deep tunnels with heavy machinery or blast it with dynamite, leaving the ore in pieces. Then the extracted lead ore will be conveyed to the crushing plant and grinding machine for size reduction. And then the crushed materials will be processed in further separation or beneficiation equipment.
Lead Ore Extraction Methods
Lead is extracted from ores dug from under-ground mines. More than 60 minerals contain some form of lead, but only three are usually mined for lead production. The most common is called galena. The pure form of galena contains only lead and sulfur, but it is usually found with traces of other metals in it, including silver, copper, zinc, cadmium, and antimony as well as arsenic. Two other minerals commercially mined for lead are cerussite and anglesite.
Lead and zinc are mined almost exclusively in underground operations although a few surface operations do exist. The selection of underground or surface mining techniques is according to the proximity of the ore body to the surface. Lead-zinc underground mining techniques use shafts, drifts, and adits to access the ore body. The most common underground mining method to remove the ore is room-and-pillar.
