Lead is extracted from ores dug from under ground min Lead is also found in conjunction with other metals such as silver and zinc Lead materials are mined as a by product of these other more valuable metals Extracting the lead materials from the ore is a tedious process First the lead ore is ground into small salt like particlLEAD INDUSTRY PROFILE In the case of lead zinc ores the metals are usually separated in a two stage process First the zinc sulphide is depressed while the lead sulphide is floated off and removed In a separate stage further additions are made to activate the zinc ore and it is floated off The froths are then broken down by water sprays and the

History of Lead Mining in Missouri It is no coincidence that Missouri s official State Mineral is Galena the major source of lead ore For most of the late 19th and early 20th Centuries Missouri was the global leader in lead production and even today some of the largest and most important remaining lead deposits in the world are located in To recoup their losses they reworked the lead rich slag and slimes from previous mining which still contained up to 25 lead Dressing floors to process the slag and a smelter complete with a boiler and flues was built in Velvet Bottom 900 m down valley from the road

Home Mining Copper Lead Zinc or Copper Lead Zinc or The Cu Pb Zn separation process is among the most challenging flotation separations primarily because the first step must entail bulk flotation of the two most readily floatable minerals with these two minerals separated in a differential flotation stage In this case as a general rule 61 Process Overview 611 Lead and Zinc Ore Mining Lead and zinc ore is nearly always mined below the surface of the ground Some veins of ore lie as deep as several thousand feet but most deposits lie close to the surface Lead and zinc ore is mined almost exclusively in underground operations though a few surface operations do exist

Smelting is a process of applying heat to ore in order to extract a base metalIt is a form of extractive metallurgyIt is used to extract many metals from their ores including silver iron copper and other base metalsSmelting uses heat and a chemical reducing agent to decompose the ore driving off other elements as gases or slag and leaving the metal base behindHistory of Lead Mining in Missouri It is no coincidence that Missouri s official State Mineral is Galena the major source of lead ore For most of the late 19th and early 20th Centuries Missouri was the global leader in lead production and even today some of the largest and most important remaining lead deposits in the world are located in

Lead for recycling may be in the form of scrap metal roofing sheet for example or compounds of lead such as the pastes from lead acid batteri Clean metallic lead can be melted and refined directly but compounds and lead alloys require smelting using processes similar to those used with lead or Two stage processBefore mining can commence the land needs to be cleared of timber and vegetation Alongside this process may be the collection of seeds and/or saplings for inclusion in a seedbank which will form the basis of post mining revegetation of the site Next the top soil is removed and is usually also stored for replacement during rehabilitation
