Abstract: An automatic panning system and method adapted for a vehicle with an attached trailer. The automatic panning system comprises an image capturing means adapted to capture image data with a view of the trailer and the automatic panning system is adapted to analyze the image data to identify at least one elongated element of the trailer, project a vector in the image data based on said elongated element, establish at least one reference vector, and identify an interception point of the reference vector and said projected vector.

Abstract: Disclosed is a method of pretreating sulphide ores or sulphide ore concentrates having high bismuth contents that have a disturbing influence on further processing of the ores or concentrates, such as to enable the ores or concentrates to be further processed for the recovery of their valuable metal contents or at least to facilitate such processing. The method is characterized by leaching the ore or the concentrate with sulfuric acid over a predetermined time period while supplying heat at a pH below 2, and thereafter separating from the leachate a leaching residue in the form of a product which is leaner in bismuth and more enriched with regard to its valuable metal content than the input material.
