  • OXIDATION OF LEAD SULPHIDE

    The stability of lead sulphate at high temperature 900 C has been investigated. Sintering behaviour of the products in relation to their incomplete desulphurization was examined. Oxidation studies on lead sulphide were extended to lead-zinc ores with respect to the effect of moisture content and bentonite on sintering.

    Lead and Zinc Sintering IntechOpen

    Sinter is the primary feedstock for blast furnace to produce lead and zinc metals and it is obtained by the oxidation sintering of fine particulate zinc/lead sulphide concentrates in updraught sinter machines. A typical flowsheet of sinter process is shown in Figure 2. The product is a partially fused porous agglomerate, which is crushed and large lump material is fed to the blast furnace.

    Lead smelting - Wikipedia

    Plants for the production of lead are generally referred to as lead smelters. Primary lead production begins with sintering. Concentrated lead ore is fed into a sintering machine with iron, silica, limestone fluxes, coke, soda ash, pyrite, zinc, caustics or pollution control particulates. Smelting uses suitable reducing substances that will combine with those oxidizing elements to free the metal. Reduction is the final, high-temperature step in smelting. It is here that the oxide becomes the ele

    Lead processing - Mining and concentrating Britannica

    Flotation separation generally is used for sulfide ores. In this process, the finely crushed ore is diluted with water and agitated violently with air in Lead processing - Lead processing - Mining and concentrating: Once the ore is removed from veins narrow channels or lodes roughly spherical deposits in the Earth, usually at depths of about 60 metres, the ore is treated at concentrating mills.

    METHOD OF SINTERING OF MINERAL SULPHIDES - BROKEN HILL ...

    This invention relates to the sintering of sulphide minerals, e.g., lead sulphide, as a bed incorporating the same is conveyed substantially horizontally, e.g., in a sintering machine of the Dwight Lloyd-type, to a discharge position at which the sinter is delivered to sinter breaking means.
