Mining in Iran - Wikipedia

Although the petroleum industry provides the majority of economic revenues, about 75 percent of all mining sector employees work in mines producing minerals other than oil and natural gas. These include coal, iron ore, copper, lead, zinc, chromium, barite (world's sixth largest producer ), salt, gypsum, molybdenum, strontium, silica, uranium, and gold (most as a coproduct of the Sar Cheshmeh copper complex operations). The mines at Sarcheshmehin Kerman Province contain the world's second larges
