Lead | Article about lead by The Free Dictionary

Lead oxides are reduced to metal. Crude lead contains 9298 percent Pb, the remainder being admixtures of Cu, Ag (sometimes Au), Zn, Sn, As, Sb, Bi, and Fe. Admixtures of Cu and Fe are removed by liquidation. Air is passed through the molten metal in order to remove Sn, As, and Sb.

Lead processing - Refining | Britannica

Lead processing - Lead processing - Refining: To remove and recover remaining impurities from lead bullion, either pyrometallurgical or electrolytic refining is used; the choice between the two methods is dictated by the amount of bismuth that must be eliminated from the bullion and by the availability and cost of energy. The Parkes zinc-desilvering process is the most widely used ...

Effect of the Addition of Different Metal Oxides in Lead ...

The paper reports the effect of addition of metal oxides in lead borosilicate glasses on electrical characteristics of SbSn alloy-based thick-film resistors. The Sb and Sn powder (1: 1 by weight) is taken in two quartz tubes separately, vacuum sealed at 10<sup>5</sup> Torr and heated in a resistive furnace .at 430 and 630 respectively.

It is captured at a separate acid plant and converted to sulfuric acid, which has many uses. After the ore has been roasted in this way, it fuses into a brittle material called sinter. The sinter is mostly lead oxide, but it can also contain oxides of zinc, iron, and silicon, some lime, and sulfur.
