Sinter Machine - an overview | ScienceDirect Topics

Apr 02, 2011· A.E. Morris, M. Wadsley, in Encyclopedia of Materials: Science and Technology, 2001. 4.1 Smelting of Lead. The conventional process for smelting lead involves roasting a mixture of lead sulfide concentrate and flux on a sinter machine, followed by blast furnace smelting.Environmental and energy considerations have prompted studies of a more direct route, a so-called "direct" smelting process.

LEAD INDUSTRY PROFILE - ILA - International Lead ...

The first stage is to remove the sulphur from the lead ore by roasting the ore in air. The lead mineral is converted to lead oxide, and sulphur dioxide gas is released: 2PbS + 3O 2 => 2PbO + 2SO 2 This is performed in a Dwight Lloyd Sintering Machine which allows continuous processing of ore. A mixture of finely divided ore concentrates and

Smelter Lead Ore Machine Sale Suppliers

12.6 Primary Lead Smelting - US EPA

12.6 Primary Lead Smelting 12.6.1 General15 Lead is found naturally as a sulfide ore containing small amounts of copper, iron, zinc, precious metals, and other trace elements. The lead in this ore, typically after being concentrated at or near the mine (see Section 12.18), is processed into metallurgical lead at 4 facilities in the U. S.

Sintering | Article about sintering by The Free Dictionary

The sintering process includes preparation of the charge, including proportioning or batching the individual components, mixing, moistening, and pelletizing; sintering a prepared charge on sintering machines; and processing the hot sintered cake by fragmentation, screening to remove lumps up to 5–10 mm, cooling up to 100°C and sorting.

Sinter Plant Operation - Metallurgist & Mineral Processing ...

The weight of the materials in the hopper is continuously measured by a couple of load cells and the machine driving speed is controlled to keep this weight constant. Oxide Use in Sintering. The original function of the sintering process of the I.S.P. is both to eliminate sulfur and to make hard sinter from zinc and lead sulfide concentrates.

The advantages and disadvantages of imperial smelting furnace

For smelting matte, blast furnace has wide adaptability, high hearth efficiency, and high thermal efficiency. So in history, it is one of the most important copper smelting methods. Traditional blast furnace top is open, only can handle lump ore or agglomerate, flue gas contains low concentration of SO2, it is not easy to effectively recycle and has environmental pollution.

Identification and Description of Mineral Processing ...

The exit gas stream from the sinter machine is cleaned and routed to an acid plant to produce concentrated sulfuric acid. The sintered material is then introduced into a blast furnace along with coke and fluxes. (SAIC, 1991b, p. 2) Inside the blast furnace, the lead is reduced (smelted), and the molten material separates into four layers:

Sinter plant - WikiMili, The Free Encyclopedia

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 …
