Zinc Mine And Market Outlook Analysis

Posted: September 24, 2013 in Materiel, metal

zinc business card

Zinc mining is the process by which mineral forms of the metal zinc are extracted from the earth through mining. A zinc mine is a mine that produces zinc metal. Some mines produce primarily zinc, but some mines produce zinc as a side-product of some metal that has a higher concentration in the ore. Most zinc mines produce zinc and lead or zinc and nickel.

1 11

zinc mining in brief

80% of zinc mines are underground, 8% are of the open pit type and the remainder is a combination of both. However, in terms of production volume, open pit mines account for as much as 15%, underground mines produce 64% and 21% of mine production comes from the combined underground and open pit mining.

33 3

Rarely is the ore, as mined, rich enough to be used directly by smelters; it needs to be concentrated. 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.

market outlook

22 2

In the future, with the increased concentration of government policy and planning support, the improved economic situation, the downstream consumption growth and trade integration of industry, these measures will promote the development of China’s lead-zinc market. In the long run, speed up the pace of industrial restructuring, eliminate backward integration industry production and other industries is the direction of future development of Chinese lead and zinc industry, the trend of. The prospects for the industry, the future will be more emphasis on energy-saving emission reduction and environmental protection, at the same time, lead and zinc industry began to turn to the international business.
