One of the possible utilizations of the by-products is by using them as raw materials for the production of commercial metals or alloys. Laboratory experiments of the production of ferro-silico-manganese alloy using manganese ore and copper smelting slag as raw materials were carried out in the present study. Manganese ore and different amounts of copper smelting slag were reduced by bituminous coal at final holding temperatures of 1450, 1500 and 1550 °C. The equilibrium compositions and phases were predicted by FactSage thermodynamic software and were used to assist the analysis of the present experimental results. The influences of temperature and the addition of copper smelting slag on the metal product size, total metal recovery, metal composition, and recoveries of elements in the metal product were determined. The final slag obtained from the reduction process were also characterized. The present study demonstrates the possibility of producing ferro-silico-manganese by utilizing manganese ore and copper smelting slag as raw materials.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Equilibrium compositions,Holding temperatures,Laboratory experiments,Manganese ore,Metal composition,Metal production,Metal products,Reduction process[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Copper smelting slag,Ferro-silico-manganese,Manganese ore,Metal formation[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]The authors would like to thank to the Program of Research, Community Service, and Innovation of the Bandung Institute of Technology (P3MI–ITB) for funding this research and PT Smelting for providing the copper smelting slag sample.
