QUALITY IMPROVEMENT FOR MAGNETITE CONCENTRATE AT THE CONCENTRATING PLANT OF LEBEDINSKII MINING AND CONCENTRATING PLANT

摘要

The problem of quality improvement of fine-comminuted magnetite concentrates is connected with forming so-called secondary (man-caused) attachments in the process of re-comminution. Usage of new type devices (such as magnetic hydro-concentrators, magnetic suspension activators) allows to separate effectively formed attachments and to rise Fe content in the concentrate.
