Abstract
Waste (tailings) of mining and processing plants of
Kryvbas were studied by the stages of their magnetic
enrichment. The granulometric compositions of the tailings,
the amount of iron (total and magnetic) and the mass fraction
of solid in them are determined. The expediency of disposing
of ferruginous quartzite waste at the first stage of enrichment
as a silica component in cellular concretes is proved. Optimal
compositions of aerated concrete mixtures are determined
based on the following criteria: the average density of cellular
concrete in the dry state and its compressive strength.
