Title
A Study on the Roasting of Stibnite
오재현Jae Hyun Oh, 유용주Yong Zou You
Abstract
Roasting of stibnite was studied in a rotary kiln type roaster with air as the oxidizing gas. The roasted ore can be used to prepare pure Sb₂O₃ by leaching process. A couple of fundamental tests was also carried out with thermal gravity analysis and tube furnace type roaster. The results obtained in the present investigation are as follows: 1) The oxidation of -200 mesh stibnite begins at about 250℃. 2) In the tube furnace roasting, the conversion of Sb₂S₃ into Sb₂O₃reaches about 95%. 3) To attain sufficient oxidation for -200 mesh stibnite in the rotary kiln type roaster, 1.8-2.2 times of the calculated amount of air should be blown into the roaster for 60 minutes at the temperature range of 360-400℃.
