Sintering of Ore Mixes Containing Iron Concentrates of a Low SiO2 Concentration of Below 1,0 %

Abstract

The investigation concerned the production of ore sinter from sinter mixes containing a concentrate of a very small grain size of below 0,1 mm and a low silicon content of below 1,0 % with an addition of 0,69 %, 8,5 % and 16 % of calcium (CaO) and 11,5 %, 16 % and 21 % of coke, respectively. The obtained sinter of a low Si content of below 1,0 % is partially metallised and may be used as an iron ore substitute for the steelmaking process.
