Cadmium. Cadmium is a soft, bluishwhite, ductile metallic element that occurs in association with zinc ores. Its main use is in the production of nickel cadmium batteries. Copper. Nyrstar produces copper in concentrate and copper cathode. Copper is a soft, but tough metal, and it is an excellent conductor of heat and electricity.
Hindustan Zinc Limited (HZL) is an integrated mining and resources producer of zinc, lead, silver and is a subsidiary of Vedanta Resources PLC. HZL is the world''s second largest zinc producer. Its FY2018 revenues were Rs 22,084 crore

Cadmium (Cd) is a very soft, silverywhite metallic element that can be cut with a knife. Cadmium has many chemical similarities to zinc and is often recovered from the primary zinc ore sphalerite. The single most important use of cadmium is in the production of nickelcadmium (NiCad) batteries. Relation to Mining
Zinctocadmium ratios in typical zinc ores range from 200:1 to 400:1. Sphalerite (ZnS), the most economically significant zinc mineral, commonly contains minor amounts of other elements; cadmium, which shares certain similar chemical properties with zinc, will often substitute for zinc .
The dumps of the past mining operations leach zinc and cadmium, and the sediments of the Geul River contain nontrivial amounts of metals. About two thousand years ago, emissions of zinc from mining and smelting totaled 10 thousand tonnes a year.

Dec 10, 2013· Cadmium is also found in meat, especially sweetmeats such as liver and kidney. In certain areas, cadmium concentrations are elevated in shellfish and mushrooms (Jarup 2002). Cadmium can also enter the food chain from water. In Japan, zinc mining operations contaminated the local water supplies with cadmium.
Cadmium is produced mainly as a byproduct of mining, smelting and refining of zinc and, to a lesser degree, as a byproduct of lead and copper manufacturing. Most of the cadmium produced is used in the production of nickelcadmium batteries, which in 2004 represented 81 per cent of the total amount of cadmium.
Jun 25, 2019· The company refined 610,000 tons of zinc in 2017, or about eight percent of global zinc production when including its sister company and subsidiary. The applications for zinc include autos, galvanized steel, and machine parts. Besides zinc, Korea Zinc is also a major refiner of lead, copper, gold, indium, nickel, bismuth, gallium, and cadmium.

The cadmium content of the zinc concentrate is usually around % to %. An estimated 90% to 98% of the cadmium present in zinc ores is recovered in the mining and beneficiating stages of the extraction process.
