6.1.2 Lead and Zinc Ore beneficiation Due to low zinc content, run-of-mine zinc-bearing ores must be concentrated before smelting and refining. Beneficiation, which usually occurs at the mine, consists of crushing, grinding, and flotation to produce concentrates of 50 to 60 percent zinc. Lead ore also requires processing to
Process. With the principle of " easiness to hardness ", Xinhai divides the recovered minerals into two parts: easy-to-float and difficult-to-float according to the difference of natural floatability, and then separate the copper, lead and zinc concentrate from the mixed concentrate.
Zinc smelting is the process of converting zinc concentrates (ores that contain zinc) into pure zinc. Zinc smelting has historically been more difficult than the smelting of other metals, e.g. iron, because in contrast, zinc has a low boiling point.At temperatures typically used for smelting metals, zinc is a gas that will escape from a furnace with the flue gas and be lost, unless specific
