METHOD OF RESOURCE-SAVING MAGNETIC CONCENTRATION OF FINELY DISSEMINATED IRON ORES

摘要

FIELD: magnetic concentration of iron ores. SUBSTANCE: method may be used in production of low-siliceous iron-ore concentrate. The method includes wet grinding of crushed iron ore and magnetic concentration of ground product in several stages. Magnetic products of the first stage of concentration of two neighboring sections of concentrating mill are combined. Obtained mixture is first finely ground and concentrated on equipment of next stages of the first section. Obtained combined magnetic product is finely ground and concentrated on equipment of next stages of the second section. EFFECT: provided production of high-grade concentrate with low content of iron in wastes and resource saving due to reduction of irrecoverable losses of mineral raw material in concentration. 1 dwg
