抄録
The thermodynamical investigations on the thermal decomposition and the oxidation reaction of arsenic-bearing copper concentrates were executed. It was found consequently that the thermal decomposition of enargite occured at the temperatures above 600°C approximately, and that, furthermore, the roasting in the atmosphere containing rich SO2 and poor O2, as well as in CO2, was exceedingly effective for dearsenising Kinkaseki are which contained enargite.<BR>Based on these fundamental experiments, the author carried out the dearsenising roasting tests of Kinkaseki are by pilot fluidised bed roaster in the atmosphere above-mentioned and clarified the conditions required for commercialisation of this method. Moreover in 1956, the author designed to put this method into practice and undertook the construction of the dearsenising roasting plant, whose daily capacity was 40 tons, in Saganoseki Smelter, Nippon Mining Co. Ltd.<BR>This plant started on commercial scale in January, 1959 and has been in operation satisfactorily and smoothly up to the present with the dearsenising efficiency of more than 80%.
