Zinc mining is the process by which mineral forms of the metal zinc are extracted from the earth through mining. A zinc mine is a mine that produces zinc minerals in ore as its primary product. Common co-products in zinc ores include minerals of lead and silver. Other mines may produce zinc minerals as a by-product of the production of ores

Silver, Lead & Zinc Flotation Circuit #2. The recovery of silver minerals occurring in a lead-zinc sulfide ore is efficiently accomplished using the above flowsheet. The process consists of selective flotation to produce a mixed silver-lead concentrate for maximum smelter return and a separate zinc concentrate.

During the milling process, ore is crushed and ground before proceeding to a flotation process, which separates the copper, zinc and lead. “In order to separate lead, zinc and copper from our ore, we use a series of flotation cells and different reagents to alternatively float or depress minerals,” stated Brad Bunn, senior metallurgical engineer at the Brushy Creek Mill. “The reagents

In the American process, zinc ore or concentrate is mixed with coal and charged into an aerated furnace. The zinc ore is reduced momentarily to zinc vapor by the heat of combustion of coal in air. Carbon dioxide and excess oxygen in the furnace oxidize the zinc vapor to zinc oxide fume which is sucked out by large fans through pipelines to settling chambers and cloth filters for collection.
