Antimony smelting slag is produced from blast furnace during antimony oxides reduction. The slag composition of such antimony smelting slag is FeO–SiO 2 –CaO, and Pb, Zn, and Sb in slag appears as complicated oxides. In the antimony smelting slag, part of Pb exists in the form of PbS.
Blast-furnace smelting today is organized so as to produce low-silicon hot metal, with subsequent desulfurization. In that case, economical furnace operation is facilitated by the use of low-ash coke characterized by hot strength and low adhesion to the slag melt, as well as stable chemical composition, minimum softening temperature …

furnace, and 45-60% antimony ores are treated by liquation or iron precipitation. A description of ... Blast Furnace Smelting: Intermediate grades of oxide or sulfide or mixed ores, liquatio n .
The blast furnace process rate is controlled by the proportion of coke in the charge and by the air flow through the tuyeres in the floor of the furnace. The charge descends through the furnace shaft into the smelting zone, where it becomes molten, and is tapped into a series of settlers that allow the separation of lead from slag.

Smelting slag is a byproduct produced in the smelting process of the blast furnace in the blast furnace volatilization smelting method. Crude antimony and antimony matte are mainly obtained by this process. Table 3 shows the composition of typical melting slag.
The phase transformation mechanism of antimony sulfide in the oxygen-enriched smelting system was investigated. The standard Gibbs free energy change (ΔG^θ) of reactions in the smelting system at 100 ~ 1400°C were calculated, indicating that the reaction between Sb_2S_3 and oxygen was liable to occur first, and that the high …
The produced slag contains high antimony and returns to the blast furnace; crude antimony contains arsenic, lead, copper, iron, and other impurity elements, which need to be further refined. In the process of refining, through the application of arsenic removal agent (sodium carbonate) and lead removal agent (phosphoric acid), the …
The main method of pyrometallurgy is the volatilization smelting in blast furnace of antimony concentrate. During the smelting process of antimony concentrate, a large amount of smelting slag is …

The process of blast furnace volatilization smelting is mainly used to treat stibnite and antimony-gold ores. But jamesonite is treated by the process of roasting-sintering-blast furnace smelting. ... Many new technologies that are applied in these traditional antimony smelting processes play important roles, such as deleading agent, …
from these furnaces for further processing in smelting furnaces or pot furnaces. 12.11.2.2 Smelting - Smelting produces lead by melting and separating the lead from metal and nonmetallic contaminants and by reducing oxides to elemental lead. Smelting is carried out in blast, reverberatory, and rotary kiln furnaces. Blast furnaces produce …
The different process that was adopted to extract antimony depends on the different raw materials. The process of blast furnace volatilization smelting is mainly used to treat stibnite and antimony-gold ores. But jamesonite is treated by the process of roasting-sintering-blast furnace smelting.
