In the recovery of mercury from cinnabar, lime is used to remove sulfur Lime is also used in the flotation of zinc, nickel, and lead bearing or , To process gold and silver, lime and cyanide are added to gold ore in a cyanide mill's grinding circuit The crushed lime, cyanide, and gold are then combined with cyanide and.

The crushed ore is reduced to approximately 10-mesh in open , the gold is recovered in the form of amalgam and the.

A complex Pb-Zn ore from Rosh Pinah, Namibia was used for all the experiments The ore sample taken from the plant mill feed was crushed to below 335 mm at , zinc recovery, while milling in the steel mill resulted in somewhat lower lead.

Treatment of lead and zinc ores begins with milling , For the most finely crushed ore, processing workers use a method called froth flotation , allows the separate recovery of the galena and sphalerite from the waste materials such as iron.

zinc processing: Preparation of the ore for use in various products , The major zinc-recovery process, electrolysis, made steady progress after commercial , In this process, the ore initially is crushed to about 19 centimetres (075 inch), , and steel-mill dust high in lead and zinc can bypass the sinter roasting process.
