sintering of fine-grained kyanite concentrate. Batches of ladle brick were prepared from kyanite con- centrate obtained from the Khizovark source.
Sintering of catalysts. Sintering is an important cause for loss of catalyst activity, especially on supported metal catalysts. It decreases the surface area of the catalyst and changes the surface structure. For a porous catalytic surface, the pores may collapse due to sintering, resulting in loss of surface area.
sintering, but the portion of +45 ˚m had the reverse effects. With increases in finer commercial concentrates (10–40 mass%) combined with low grade ore (10–20 mass%) in iron ore blends, the productivity also did not obviously change.

Raw Material Iron Ore Concentrate for Sintering Raw material iron ore concentrate for sintering Brief introduction: Iron ore concentrate is used as a metallurgic raw material in iron smelting. Iron ore concentrate recovery is based on magnetic beneficiating methods.
Sintering is thermal treatment of fine-grained material at a temperature below the melting point of the main constituent, for the purpose of increasing its grain size and strength by bonding together the particles.
The concentrate particle size distributions therefore are not favourable for sintering. The chromite concentrates are mainly composed of chromite grains and gangues of magnesium silicates. Because of its refractoriness and low rate of dissolution in gangue, the chromite minerals participation in liquid phase formation during the sintering ...

iron ore concentrate in the sintering process, four tests  including assimilability, liquid fluidity, bonding phase strength, and crystal strength  were carried out using the micro-sinter equipment. The Australian iron ore concentrate was dried at 105°C
The iron ore concentrate is now mixed and ready for the pelletizing process. Pelletizing A pellet plant contains a series of balling drums where the iron ore concentrate is formed into soft pellets, in much the same manner that one rolls a snowball, to make a pellet about

The sintering of ceramic materials from powders has been the subject of intense research over the last century. The use of high temperatures and long holding times in traditional techniques, such as pressureless sintering or hot pressing in conventional furnaces, has been a limiting factor for the industrial application of ceramic materials.
