  • Lead And Zinc Energy

    Lead and zinc ores are usually found together with gold and silver. A lead-zinc ore may also contain lead sulfide, zinc sulfide, iron sulfide, iron carbonate, and quartz. When zinc and lead sulfides are present in profitable amounts they are regarded as ore minerals. The remaining rock and minerals are called gangue. Forms of Lead and Zinc Ore

    Slags of this group are often black to red in color and glassy. They have sharp, angular particles that are cubical in shape. The unit weights of lead, lead-zinc, and zinc slags are somewhat higher than conventional aggregate materials. Granulated lead, lead-zinc, and zinc slags tend to be porous, with up to 5 percent absorption.

    Jul 01, 2019 However, lead slag only accounts for approximately 5 of the raw ingredients. In a different study, researchers used the lead and zinc smelting slag as the ferrous raw material to produce Portland cement, entirely replacing iron ore Li et al., 2004. The results showed that the burnability of a mixture of 6 slag had obviously improved.

    The lead is refined in a cast iron kettle by five stages. Antimony, tin and arsenic are removed first. Then zinc is added and gold and silver are removed in the zinc slag. Next, the lead is refined by vacuum removal distillation of zinc. Refining continues with the addition of calcium and magnesium.

    The green, or unroasted, charge is first oxidized in a molten bath by the submerged oxygen injection this produces a flue gas carrying oxides of lead and zinc as well as a slag containing 80 percent of the zinc from the charge. Reduction of the metal oxides occurs when they contact carbon monoxide produced by the natural-gas injection.
