Abstract
1406153 Refining sulphide ores MITSUBISHI KINZOKU K K 4 May 1973 [4 May 1972] 21266/73 Heading C7D Metal sulphide ore (e.g. copper, nickel or cobalt ore) is refined to produce crude metal by (a) changing into a smelting furnace 1 together with air, flux (e.g. silicic ore) and fuel to produce a melt comprising a matte and a slag and adding thereto a blister furnace slag from step c, (b) feeding the melt from the smelting furnace to a separator 2 so as to separate the matte and the slag and to discharge them separately therefrom and (c) changing the matte together with flux (e.g. lime) and air into a blister furnace 3 to produce a white metal and/or a crude metal and a blister furnace slag which is recycled to step a, the white metal where formed being subjected to a further refining step (e.g. electrolysis, reduction, flatution or the use of a second blister furnace) to produce crude metal. The raw material may be fed continuously in roasted form to the smelting furnace and the residence quantities of matte, slag, white metal and crude metal in the various stages maintained constant by equilibrating the rate of transfer of the melt between the various process steps (e.g. by the use of overflow weirs and an adjustable damper 9) and the rate of feeding of flux, air and optionally coolant e.g. cold scrap to the blister furnace. A reducing agent e.g. coke or pyrites may be added to assist separation of the matte and slag in separator 2 and the recycling of the blister furnace slag to the smelting furnace may be achieved by means of a bubble pump, bucket conveyer, electromagnetic means or gravitational means in which the matte from separator 2 is transferred to blister furnace 3 by forced means. The exhaust gases from 1 and 3 and separator 2 may be collected and utilized in sulphuric acid manufacture.
