Abstract

Magnesite, after thermal treatment is mainly used as a refractory material in steel making, cement and nonferrous metals. Recent development of these industries in Iran has increased the demand for magnesia.The major magnesite deposits in Iran are located in the east and eastern south parts. Refractory production plant, erected in Birjand produces about 30,000 tpy dead burned magnesia. The high grade feed crushed, screened and the fraction finer than about 3 mm separated and disposed as tailing. It is too fine in size to be treated in the kiln. Also its free silica content is higher than the coarse fraction.The present work presents the results obtained for reduction free silica of a representative sample of the tailing dam by gravity and flotation methods.After characterisation of the sample, it was divided into various size fractions, on which heavy liquid tests were carried out. The results revealed that by means of a 2.8 gr/cm3 liquid a concentrate with 92.5% magnesite, 2.1% Sio2 and 3.7%CaO.Flotation tests were performed with cationic collectors in alkaline conditions. Initial results showed that desliming of the feed was essential. By using collectors . Initial A17 or A18 manufac tured by AKZO, a product containg more than 91% magnesite and less than 2% Sio2 . The briqueting of the concentrate is necessary to feed the klin.
