Zinc production - Galvanizers Association

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, usually in the form of zinc sulphide. Zinc concentration is usually done at the mine site to keep transport costs to smelters as low as possible. Zinc concentrates are then roasted or sintered to ...

Zinc production environmental impact

Mining resources are estimated at a level of 220 million tons of currently exploitable zinc ore reserves. Annual world consumption of zinc is at present 9.7 million tons. Since recycling accounts for about 39% of zinc consumption, zinc reserves are depleted at a yearly rate of 5.9 million tons. Increased recycling will compensate for future growth in consumption. On the basis of constant ...
