Latest Patents

Colin Bruce MacKenzie holds a patent for his invention titled "Fluid bed roasting of metal sulphides at high temperatures." This patent describes an improved method 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, allowing the sulphides to be roasted effectively. The controlled feed rates of sulphide, water, and free oxygen-containing gas facilitate optimal temperatures for fusion during roasting, resulting in the formation of agglomerated calcine particles with regular, rounded surfaces. This method is particularly advantageous for roasting pyrrhotite concentrates and other sulphide concentrates derived from nickel-copper ores in the Sudbury Basin.
