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.
Briquetting in ferrous metallurgy is the earliest way clotting. In the beginning of XX century briquetting has been forced out by agglomeration basically for the reason considerably more productivity of process of agglomeration. As alternative to agglomeration pelletizing became. It started to be popular in the XX-th century, that is quite explainable by essential increase of manu- facture fine particle concentrates. However briquetting has a number of advantages. For some kinds of iron ores briquetting can be preferable process. Such ores are rich iron ores with iron content 60 % and more. The technology of briquetting includes crushing, preliminary screening for removing of large particle size classes; dispensing and mixing martite ore, and hydrohematite ores; mixing with binder substances; pressing; screening for removing of small size briquettes; drying. The received briquettes have density 3200-3600 kg/m3, durability on uniaxial compression more then 4,5 MPа.
Rich iron ores of the Jakovlevsky deposit are fine metallurgical raw materials. These ores are suitable for melt of high-quality metal at the minimum cost price as doesn't demand mineral processing. Ores contain a considerable quantity of fine classes particles and need briquetting. Mining operations include quality control of mined ore. The technology of briquetting includes, preliminary screening for removing of large classes; dispensing and preliminary mixing 85-90 % martite, iron-micaceousmartite ores and 10-15 % hydrohematite ores; mixing with connective substances; pressing; drying. The received briquettes have density 3200-3500 kg/m 3 , durability on compression 4,5 MPа.
