METHOD OF PROCESSING MINERAL STOCK AND DEVICE TO THIS END (VERSIONS) Russian patent published in 2010 - IPC C04B7/43 C21B11/00 

FIELD: process engineering.

SUBSTANCE: invention relates to mining and can be used in cement and iron-ore concentrate production. Proposed comprises preparing the stock consisting of limestone component, iron ore and coal, their fractionating, if necessary, dewatering and mixing, sintering including drying and calcinating, thermochemical reaction between stock components and calcination products, mixing thermochemical reaction products and cooling down calcinated mass, producing commercial product including mincing cooled mass to required grain sized and, if required, enriching and compacting. Said stock that features complimentary physical-chemical properties that allow producing cement clinker and iron-ore concentrate, comprises limestone with content of CaO - 52.0-52.5%, iron ore with content of Fe₂O₃ - 42-44%, SiO₂ - 22-27%, Al₂O₃ - 4.0-4.3%, brown coal with content (in its ash) of SiO₂ - 50%, Al₂O₃ - 25%, the ratio between said components making 4:3:1. Produced sintered product, after cooling and mincing, is separated by magnetic separator into cement clinker and iron-ore concentrate. Invention covers also design versions of the devices to impellent described method.

EFFECT: reduced power consumption, higher efficiency.
