Zinc Mines - an overview ScienceDirect Topics

Due to the lower melting and boiling points of zinc at approximately 420°C (788°F) and 907°C (1665°F), respectively, zinc smelting and converting are conducted at lower temperatures than those of copper, noting that the copper has a melting point at 1085°C (1985°F) and copper concentrate does not melt even at a temperature as high as 1500°C (2732°F).
