DESCRIPTION :

Shivakumar Angadi is having research as well as industrial experience. His PhD thesis was on “Conventional and column flotation studies on graphite and coal fines”. This research work involve studies on interaction between solids, liquid and air phases in the flotation machines, which has helped in analyzing the mechanism of transportation of solids and water to the froth products. Later, Dr. Angadi was associated with Mineral Processing SBU, Tega Industries Ltd., Kolkata, wherein, he got exposed to industrial practices [about two and half years]. He was in-charge of mineral processing laboratory and was responsible for technical inputs to the commercial offers. He was also assigned responsibilities like selection of hydrocyclones, flowsheet development, plant commissioning, conducting plant level test works, improvement of the laboratory facilities etc. During his tenure in Tega Industries many plant commissioning/test works were carried out successfully. Presently, Dr. Angadi is working on process development for the beneficiation of low-grade ores, slimes, and waste generated during mining/mineral processing activities. The studies are oriented towards coarse size beneficiation using jigs and slimes beneficiation using advance gravity separators, magnetic separators, flotation etc. He is involved in teaching of unit operations to M.Tech and Post-Graduation Diploma in Mineral Engineering (PGDME) students of the Institute and supervising their project works.
