This chapter compares the economic feasibility of direct-to-copper flash smelting and flash smelting/flash converting for different copper concentrate grades. The objective is to evaluate their respective industrial oxygen and hydrocarbon fuel requirements across varying copper content scenarios. The methodology employs calculations based on the energy costs associated with electric furnace recovery from direct-to-copper slag, alongside the combined fuel needs derived from both processes. Significant assumptions are streamlined to ease the comparison, including the recycling of smelting and converting dust back to their respective furnaces. Results indicate that flash smelting/flash converting emerges as the more economical process for concentrates containing less than or equal to 35% copper, while direct-to-copper flash smelting proves advantageous for those with around 45% copper. For concentrates within the 35-45% copper range, the choice of process becomes dependent on local conditions, suggesting a nuanced approach to selecting smelting techniques based on specific operational contexts. This analysis is intended to aid operational decision-making in the copper smelting industry.
