Aug 07, 2020· Particularly, blend the sulfide form of zinc ore is the most abundant, and the first source of zinc metal. In fact, metallurgists refer to all zinc sulfide ores by blend and give the name calamine to others. The blend is usually associated with galena (lead sulfide) but it also contains inclusions of other metals (Cu, Ag, Cd, Ba, and Ge).

Doubtless a concentrate of zinc may be saleable for any metallurgical process, but in Canada, with its vast water-power resources, the electrolytic process is obviously the right one. It is not surprising that any attempt to produce electrolytic zinc in this country 10 or 15 years ago should break down partly on the score of cost of power.

Zinc ores contain 5-15% zinc. To concentrate the ore it is first crushed and then ground to enable optimal separation from the other minerals. Typically, a zinc concentrate contains about 55% of zinc with some copper, lead and iron. Zinc concentration is usually done at the mine site to keep transport costs to smelters as low as possible.

Zinc processing

The process is carried out in a series of tanks. As the lead and zinc minerals are less readily wetted than the gangue, they adhere to the air bubbles which are carried to the surface. The rock particles sink and the lead and zinc ores are skimmed off. Then the lead ore is separated from the zinc ore.
