  • Lead Materials – Ore Extraction Lead Shielding, Lead

    Extracting Lead Materials from Ore Lead is a dense, soft, lowmelting metal Lead is the densest common metal except for gold, and this quality makes it effective in sound barriers and as a shield against XraysLead resists corrosion by water, so it makes a longlasting roofing material Only about half of the lead materials used today are produced from mining, the rest is obtained fromThe lead ore concentrate from the flotation tanks now contains about 50% lead and ca 01% of silver, a relatively small but valuable amount (b) Smelting Smelting is usually a twostage process as described here, although singlestage methods with lower energy use and emissions are also usedLead Essential Chemical IndustryReaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulfuric acid to produce a very dilute copper(II) sulfate solution Concentration of the copper(II) sulfate solution by solvent extractionThe Extraction of Copper Chemistry LibreTexts
