their ores. smelting makes use of heat and a chemical reducing agent to decompose the ore, driv ing off other elements as gases or slag and leaving just the metal base behind. the reducing agent is commonly a source of carbon such as coke, charcoal. sintering is the process of compacting and forming a
this process is commonly employed for some of the metals like tungsten which have high melting points. for example, pulverised tungsten oxide is heated in a current of hydrogen; the hydrogen reduces the oxide to metallic tungsten powder. pure iron is made from iron oxide or ores of iron such as magnetite and hematite.

the manganese ore sample was screened into four size fractions (16+5 mm, 5+1 mm, 1+0.2 mm, and 0.2 mm) for sinkfloat tests. the chromite ore sample was obtained from rod mill discharge of an operating mine in the adana region of turkey. the ore consisted of magnesiochromite ((mg,fe)(cr,al) 2 o 4) with density of 4.2 g/cm . read more
process creates very large as-cast grains that result in poor workability, so arc-cast ingots must be extruded at high temperatures to refine their grain size before further processing. this combination of factors mean the arc-cast process produces a narrower range of mill product sizes and geometries than the press-sinter process.
