Lead Mining - Concentration process, flotation, filtering, roasting ...

The flotation process helps in bringing out the sulfur-bearing portions of the ore, since it also contains the valuable metal. The finely crushed ore is diluted with water and then poured into a tank. The mixture of water and ground ore together is called slurry to which a small amount of pine oil is added.
