Abstract
Clays from near Kone village,7 miles south of Masulipatam, Madras, contain native sulphur of biochemical origin. Optimum conditions for the flotation of sulphur from these clays have been investigated. Straight flotation of sample No.7B,assaying 21.8 percent free sulphur, using light diesel oil and cresylic acid gave a rougher concentrate containing 52.7 percent sulphur with 80.9 percent recovery. Reflotation improved the grade to 66.0 percent with 59 percent recovery. Additions of soda ash and sodium meta silicate to raise the pH, increased the percentage recovery to 94.1 at a pH of 7.2,but lowered the grade to 42 percent sulphur. Two other samples No.4 and No. 6 were not investigated in detail on account of their low sulphur contents.
