A number of publications in this issue are devoted to the problems of man-causedwaste mineral materialsutilization.

In particular, with regard to man-causedwaste manganese-containing materials, the methods ofhydrometallurgical treatment with application ofreducers are proposed as an alternative to roasting, which producesdetrimental effect on theenvironment (the article by N. S. Bekturganov, et al.).

Promising alternative methods for aged pyrite-containing tailings beneficiation are considered with the view of gold recovery (the article by A. V. Bogdanovich, et al.).

A method of all-round utilization of tungsten production waste materials, permitting to recover secondary tungsten raw material and mineral concrete admixture, is presented (the article by S. I. Yevdokimov and V. S. Yevdokimov).

On the basis of laboratory studies and theoretical calculations, it has been established thatcellular glass aggregates for light-weight concretes may be produced from granite fine-dispersed size fractions and granite screenings (the article by V. А. Kutolin, et al.).

A process has been developed with a view to involve difficult-to-treat wastepit-run fines into production, through application of special screening principals with respect tooutsize fine fractions, and applying vibro-impulse action with respect to crushed material, providing for production of high-gradebroken stone of 5-10 mm size (the article by P. А. Spiridonov and O. V. Zakharenko).
