The various raw materials after proper preparation and blending are treated in Kaldo - Top Blown Rotary Converter (TBRC) for melting and processing to Black Copper having 85-90% copper. The furnace is provided with high capacity oxy-fuel burner lance, concentrate lance and converting lance for required metallurgical processing. The furnace is also designed to carry out converting process to produce directly 98-99% copper.

The black copper is further processed in the Pierce Smith Converters to produce copper with purity of 98.5 – 99%. Copper having purity of 98.5 – 99% is further refined in Anode Furnace. The anodes are cast and sent to refinery for producing LME Grade “A” Copper Cathodes.
