Controlling copper matte converters, for producing blister copper, by controlling start of blowing and flow of air introduced to mimimize gas and solid emission

摘要

A method for controlling the operation of copper matte convertors, for obtaining blister copper, involves controlling: (a) the start of blowing, so that it is always carried out with the nozzles at the same distance from the bath surface, independent of the bath level; and (b) the flow of air introduced, irrespective of its position, to minimize emission of gases and solids during the start and end of blowing.
