Pulse method of magnetite demagnetizing

2020-10-8  To provide disclosure of magnetite grains during the enrichment of magnetite quartzite there is a need to mill them to a particle size less than 50 μm. This process is carried out in ball mills with three-stage central discharge. Presence of the finished class in grinding zone reduces speed of the process and leads to undesirable overgrinding of magnetite grains. As a consequence, it increases the cost of magnetite quartzite enrichment. Discharge of the finished class is performed by external devices such as spiral classifiers at first stage of grinding and hydrocyclones at the second and third stages. The value of circulating load coefficient of the mill, which exceeds 200% in existing enrichment schemes, depends on the efficiency of the classify-ing devices. Efficiency of classification of magnetite particles with fineness of 50 microns in hydrocy-clones of HC-500 series does not exceed 80%, if not to take into account their magnetic flocculation. Magnetic separation is applied after each stage of grinding. As magnetite particles have residual mag-netization, it leads to their magnetization.
