Lead and Zinc Sintering | IntechOpen

1.2. Why sintering. Lead and zin metals are produced in blast furnace. In a blast furnace, ore, coke and flux are continuously supplied through the top of the furnace, while air (sometimes with oxygen enrichment) is blown into the lower section of the furnace, so that the chemical reactions take place throughout the furnace as the material moves downward.

Vacuum sintering furnace for smelting metal powder

However, vacuum induction sintering is also used at high sintering temperature (500 ~ 2400 C), especially in the cutting tool industry. Composition of equipment: The equipment of vacuum induction sintering furnace is similar to that of crucible central induction melting furnace. The furnace body is usually made of a well or bell.

Lead smelting - Wikipedia

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.

Sintering - Wikipedia

Sintering or frittage is the process of compacting and forming a solid mass of material by heat or pressure without melting it to the point of liquefaction. Sintering happens naturally in mineral deposits or as a manufacturing process used with metals, ceramics, plastics, and other materials. The atoms in the materials diffuse across the ...
