Cadmium - Wikipedia
Thus, cadmium is produced mainly as a byproduct of mining, smelting, and refining sulfidic ores of zinc, and, to a lesser degree, lead and copper. Small amounts of cadmium, about 10% of consumption, are produced from secondary sources, mainly from dust generated by recycling iron and steel scrap.Mining in Zambia - Wikipedia,Konkola Copper Mines (KCM) is the largest copper mining company in the country.
