Abstract

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.
