High-ratio pellet ore utilization in blast furnace smelting aims to augment the fluidity of the slag, diminish its density, lower the blast furnace's thermal burden, and enhance the reducibility of the ore [6]. However, optimizing pellet ore proportion presents challenges, notably the need to balance the charge's acidity and basicity.

The flash smelting process essentially consists of dispersing and oxidizing a dry concentrate in an oxygen-enriched air stream [10]. Both flows enter through a set of chambers and ducts into the concentrate burner which disperses the gas/solid mixture into a vertical cylindrical chamber or reaction shaft. When the suspension leaves the reaction ...
