Reduction of briquette composite made of low grade from ore and biomass ash

Mini blast furnace project has been constructed to increase pig iron production for domestic consumption produced by HyL process. Malaysia has no significant high grade iron ore deposit white domestic low grade ore could not utilized for direct reduction process. Beneficiation of the low grade ore...
