Latest Patents

Coulter holds a patent for a method titled "Fluid bed roasting of metal sulphides at high temperatures." This patent describes an improved technique for agglomerative fluid bed roasting of metal sulphide particles. The process involves feeding sulphide particles as an aqueous slurry through the freeboard of the roaster onto a bed of roasted calcine agglomerate particles. The method ensures that the slurry water is evaporated in the bed while the sulphides are roasted. The controlled feed rates of sulphide, water, and free oxygen-containing gas allow for optimal temperatures, leading to the formation of agglomerated calcine particles with regular, rounded surfaces. This innovative method is particularly beneficial for roasting pyrrhotite concentrates and other sulphide concentrates derived from nickel-copper ores.
