Abstract
The non-tailing technology for processing of high grade iron ore Yakovlevsky deposit was created. The technology allows obtaining high-quality competitive product for iron and steel industry and in addition producing very high demand and competitive red iron oxide pigment. As the basis of beneficiation cycle, fine grinding of material with close circuit classification in hydrocyclones can be considered. To produce briquettes mixture of martite, hydro-hematite ores and non-pigment fraction, which is obtained in pigment cycle, are used. The ore is subjected to pre-screening. A coarse grain is used as final material for metallurgical processing. The fine grain is sent to the briquetting.
