Abstract
One of the possible fields of application of wet magnetic separation waste of ferruginous quartzite was considered in the paper. For Belgorod and neighbouring regions, the problem of this waste utilization is quite acute. The most effective specific surface of the filler, by which the averaging of grains with insignificant inclusion of larger aggregates is observed, was revealed. At that, large particles of technogenic sand, presented mainly by contact metamorphic quartz, facilitate the grinding intensification, acting as peculiar additional grinding bodies, but the grains themselves in waste magnetic separation (WMS) acquire a rounded cubical form, increasing packing density of the mixture. The use of finely ground microadmixture in cement showed that introduction of 1 % of the waste mass of wet magnetic separation of ferruginous quartzites with the specific surface of 600 m2/kg increases the cement strength approximately 1,7 times.
