  • Combination Crusher

    Combination Crusher

    The compound crusher is used to crush a variety of medium hard ores, such as limestone, clinker,coal and other ores, which can be widely used in mining, metallurgy, refractory, cement, coal,glass, ceramics, electric power and other industries, and is one of the commonly used equipment in the crushing production line and the sand making production line. This series of crusher is a new product based on our company's PEL vertical compound crusher and optimized with domestic and foreign fine crushing technology. Its performance has reached the domestic advanced level. It is mainly for all kinds of ore with compressive strength not exceeding 200MPa and water content less than 15%.

behavior of tin and antimony in secondary copper smelting

behavior of tin and antimony in secondary copper smelting

In this study, the distribution of tin and antimony between metallic copper and iron-alumina spinel saturated iron silicate slag, with 0–5 wt % K 2 O, was experimentally studied. The experimental temperature was selected as 1300 °C, which is in the same range as processing temperatures in industrial operations

Jul 17, 2012 · This process consisting of heating molten antimony sulfide in crucibles with slightly more than the (6) Sb 2 S 3 + 3Fe → 2Sb + 3FeS theoretical amount of fine iron scrap, depends on the ability of iron to displace antimony from molten antimony sulfide. Sodium sulfate and carbon are added to produce sodium sulfide, or slag is added to form a light fusible matte with iron sulfide and to facilitate …

mits accidental smelting discovery unlocks the potential

The traditional method of producing antimony metal is through heat smelting. However, researchers at MIT claim to have accidentally stumbled upon a new method of smelting using electrolysis rather than heat. Research was funded by the US Department of Energy, the Advanced Research Projects-Energy (ARPA-E), and French energy company Total SA

viscosity property of gold-antimony smeltingslags by

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 , 16.17% CaO, 25.97% FeO, 10.25% Al 2 O 3 , 5.17% MgO, the viscosity can be decreased by reducing 3.24%–8.5% SiO 2 or increasing 3.31%–9.56% CaO content

behavior of tin andantimony in secondary copper smelting

This article investigates the behavior of tin and antimony, both commonly present as trace elements in electrical and electronic waste, in secondary (i.e., sulfur-free) copper smelting conditions. The experiments were conducted in oxygen partial pressure range of 10 −10 –10 −5 atm, covering the different process steps in copper smelting. The basis of the equilibrium system was metallic copper–iron …

cleaning of high antimony smelting slag froman oxygen

Mar 25, 2015 · Cleaning of high antimony smelting slag from an oxygen-enriched bottom-blown was tested by direct reduction in a laboratory-scale electric furnace. The effects of added CaO, mass ratio of coal (experimental) to coal (theoretical) (ω) and the slag type on the reduction procedure were considered. The contents of Sb and Au were investigated. Iron contamination of the metal phase was …
