END-OF-LIFE MODE OF FAILURE OF A ZINC SULPHIDE

2007-7-26  Zincor has two large and two small roasters with hearth areas of 35 m2 and 18 m2 each respectively. By current world standards these are relatively small roasters. Modern roasters are being built with capacities of up to four times the large roasters at Zincor. The largest Lurgi roasters now have hearth areas in excess of 120 m2 [1].

The Principles of Processing Siderite Ores with a High

Due to the depletion of high-quality iron ore, it is becoming ever more urgent to involve the ores which, for some reason or other, could not be used in metallurgy, or were used in limited quantities. For example, the siderite ores of Bakalsk deposit (Chelyabinsk region, Russia, stocks of more than 1 billion tons) are of very limited use in the blast-furnace practice because of the relatively

Use of Bakal Deposit Siderite Ore in Iron and Steel

2017-5-19  Bakal siderite is lean iron ore that is difficult to process. Reduction of iron from oxide in siderite is performed either by gaseous (natural gas conversion products),or solid (carbon) [11, 12] reducing agents with achievement of a degree of metallizing of more than 90%. The concentrate obtained as a result of reduction is subjected to enrichment.

Moreover, the iron grain is closely associated with slag. With 12% dosage of alkaline oxide additive (Na 2 CO 3:CaO = 1:1), the reduction of siderite is reinforced.
