roasting furnace in use- 1 the horizontal, multiple-spindle type, of which the Edwards furnace and modifications of it are typical 2 the rotary kiln and 3 the vertical, multiple-hearth furnaces with rabbie arms attached to a central shaft, of which the Wedge furnaces used at Beattie are typical. Modifications
The vertical furnace reduction roasting has been widely used in the ore 75-20mm , the magnetizing roaster is rarely used in the powder ore less than 20mm. At present, strong magnetic separation, gravity separation, flotation method or combined process are often used to separate powder ores for the beneficiation of iron ore.

Ore concentration is roasted to reduce impurities, including sulfur, antimony, arsenic, and lead. The roasted product, calcine, serves as a dried and heated charge for the smelting furnace. Smelting of roasted calcine feed or unroasted green feed ore concentrate produces matte, a molten mixture of copper sulfide Cu2S, iron sulfide

Overview The production of pellet is like the sinter production, it supply beneficiated burden for blast furnace, the production process will produce the pellets from iron ore concentrate or powder materials.The prepared raw materials are made into certain size pellets after batching and blending in certain pro portion, then adopt drying and roasting method to produce a series of physical ...
rectangular furnace up to 10 m wide and 35 m long with internal brick lining. Throughputs of up to 1100 td concentrate or a mixture of concentrate and calcine could be processed. The charge is passed into the furnace near the burners through the roof or lateral openings. As fossil fuel, pulverized coal, heavy oil, or natural gas is used.

Blast furnace has been used for ironcoppercopper -nickelzinclead and zinc-lead complex concentrate smelting for a long time. It plays a fundamental role to modern metallurgy Feature Address
The roasting process changes some of the CuFeS 2 to copper oxide removes some of the sulfur as sulfur dioxide This is done by heating the concentrated ore from froth flotation. It is heated to between 500 C and 700 C in air. The product from the roaster is called calcine. It is a solid mixture of oxides, sulfides and sulfates.
Roasting of the produced pellets was performed in a thermo balance apparatus shown inFigure 2 28. It con - sists of a vertical furnace, an electronic balance for monitoring the weight change of reacting sample and a tem- perature controller. The sample is placed in a nickel chrome crucible, which was suspended under the electronic
