After net smelter returns, this would have yielded revenues in excess of US100 million at current commodity prices.
Get PriceLead commonly occurs in mineral deposits along with other base metals, such as copper and zinc. Lead deposits are broadly classified on the basis of how they are formed. Lead is produced mainly from three types of deposits: sedimentary exhalative (Sedex), Mississippi Valley type (MVT), and volcanogenic massive sulfide (VMS).

Get PriceZinc 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, iron, because in contrast, zinc has a low boiling 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 ...
Get PriceThe established leadzinc ore flotation processing scheme is to add zinc sulphate (ZnSO4) to the grind to control metal ion activation (sphalerite depression). Often metabisulphide or other sulphidation chemicals are added with the zinc sulphate for iron sulphide mineral depression.
Get PriceAlso, the recovery of silver minerals occurring in a lead, zinc sulfide ore is efficiently accomplished using Flowsheet 2. The process consists of selective flotation to produce a mixed silver, lead concentrate for maximum smelter return and a separate zinc concentrate.
Get PriceLead and Zinc Ores Minerals of lead and zinc commonly are rather closely associated in nature; zincfree lead ores and leadfree zinc ores are exceptional rather than common, although there are such. Lead and zinc ores usually contain some silver, but those of the Mississippi Valley region are silverfree. Indeed, leadzinc ores often are commercially valuable chiefly because of their silver ...
Get PriceOct 07, 2019· After the lead or zinc ore was removed from near surface (lead) or deeper underground mines (zinc), it was concentrated by using water to separate the heavier metalbearing minerals.
