Lead Ore is found from ores dug from ground mines. Some form of Lead
is found in many minerals but the Galena is a one of the most
important product for getting Lead. The Galena has only Lead and
Sulphur which is called pure Galena. But most of Galena is found
with minor metals including copper, zinc, calcium, arsenic and other
metals. Mostly Lead Ore is obtained as a byproduct of metal mining
Many steps are used for obtaining the Lead from Lead Ore (Lead Ore
Refining Process), these process/steps are mining the Ore,
Concentrating the ore, Flotation, Filtering, Roasting the ore,
Blasting, Refining, and Casting:
Mining: The first step for obtaining the lead-bearing ore is to
mine it underground. For it heavy machinery is used to drill the
rock from deep tunnels or it can be blast with dynamite and then
Lead Ore is obtained in pieces.
Concentrating the Ore: After removing the ore from the mine, it is
treated at a concentrating mill. In Concentrating process all waste
rock is removed from the Lead.
Flotation: The flotation process collects the sulfur-bearing
portions of the ore, which contains the valuable metal. In Flotation
process many other chemicals are also added to help concentrate the
minerals. Lead is separated from the rock and the mineral e.g.
copper. Zinc at the end of the flotation process.
Filteration: In filteration process concentrate flows to a filter
and up to 90% of water is removed. At this point the concentrate
contains about 50 % of lead, with large amounts of other impurities,
mostly sulfur and zinc.
