Smelting Reduction Technologies

In the case of iron ore smelting the off gas from the furnace consisting mainly of carbon monoxide and hydrogen can be used for pre reduction of the ore other applications of the process such as reclaiming of alloying metals from baghouse dust the produced gas is utilised as a fuel gas If the raw material contains metals with high vapour pressures for example zinc and lead these

USA

A process of removing iron impurities from ores particularly useful for removing stains of iron impurities adhered to silica sand particles comprises grinding the ore washing and desliming the ground ore to remove the major part of the clay type binder attrition scrubbing the deslimed particles to release further amounts of binder therefrom washing and desliming to remove said binder
