The method comprises the steps that: stibnite, iron ore, stone and anthracite, which are taken as raw materials, are weighed and then smelted and reacted in a bottom blowing oxidization smelting furnace to generate fume and melts; the melts are settled ...
Key Pieces of Equipment in Smelting. A crucial component in creating lead is the blast furnace. The furnace is a giant steel stack that typically gets lined with refractory bricks. Its purpose is to create liquid iron from chemically transforming iron oxides. Limestone, coke and iron ore are also thrown into the blast furnace.
Blast Furnace, Seconday Lead Smelting. GBF Blast Furnaces: We have designed and developed a special blast furnace, the GBF (patent pending), for Secondary Lead Smelting which combines the features of low set-up and operating costs, high process efficiency, low maintenance requirements due to no moving parts and user-friendly features.
The lead mix then passes to a reverberatory "softening" furnace, where the temperature is raised and the molten lead is stirred. A blast of air oxidizes any remaining antimony or arsenic, both of which harden lead (hence the term softening furnace), and these are skimmed off to be recovered later.

Slag of gold-antimony ore blast furnace smelting has seldom been studied. In this paper, the viscosities of gold-antimony ore smelting slags of different composition have been studied by the rotating cylinder method. The results showed that, for a slag of 38.95% SiO 2, ...
The effect of slag composition on lead losses to slags and on the behavior of associated accessory elements in lead blast furnace smelting has been studied by the Bureau of Mines. Equilibrations of 30 g of lead and synthetic slag doped with cu, in, tl, and sb at 1,200 deg c in co-co2 atmospheres ...
Antimony is extracted mainly from ores containing antimony trisulphide in the form of stibnite. Rich ores are first subjected to liquation, whereby the fusible sulphide is removed from the gangue and concentrated. The concentrate is then reduced to metal by smelting with wrought iron in pots, in reverberatory furnaces or sometimes in blast

In the case of slags produced from blast-furnace practice, smelting similar materials, I have never found more than 0.015 per cent, of arsenic, and only traces of antimony. It is, therefore, probable that the elimination of these elements in blast-furnace practice is almost entirely due to volatilization.

Blast furnaces are similar to furnaces but can smelt only ore blocks. When smelting, once an item and a fuel are placed into the blast furnace, the block state changes to lit and the item smelts twice as fast as a regular furnace. Fuel is also used at double the rate of regular furnaces, so that the number of items cooked per fuel stays the same.
The lead containing components are processed in blast furnaces for hard lead or rotary reverberatory furnaces for fine particles. The blast furnace is similar in structure to a cupola furnace used in iron foundries. The furnace is charged with slag, scrap iron, limestone, coke, …

The Blast Furnace is a members-only minigame situated in Keldagrim for smelting bars which require coal. The furnace here only requires half as much coal when smelting usually, so it can be useful when smelting the ores that require more coal. The Blast Furnace worlds on Old School RuneScape are...
blast furnace to recover residual lead. Aluminum chloride flux may be used to remove copper, antimony, and nickel. The antimony content can be reduced to about 0.02 percent by bubbling air through the molten lead. Residual antimony can be removed by adding sodium nitrate and sodium hydroxide to the bath and skimming off the resulting dross.
Viscosity of slag determines the production efficiency, energy consumption and distribution of elements between metal and slag, which is very important for pyrometallurgy. Slag of gold-antimony ore blast furnace smelting has seldom been studied.
China now leads the world in antimony production, having contributed during recent years something over 60 per cent, of the world's production. The history of the antimony industry of China dates back to 1897 when the Tai Shing Co. was formed, under contract with the Hunan Bureau of Mines, for the smelting of the ore to crude; and in 1908 the Wah Chang Mining & Smelting Co. was formed for ...
