Conclusion
Laboratory and technological study on concentration tailings of gold bearing quartzite of Madneuli deposit,
obtained by enriching the quartzite in semi-industrial conditions, have shown that they can be used as the main raw
material for the production of silicate wall materials.
Sand-lime brick, heavy products and cellular concrete in its physical and mechanical characteristics meet the
requirements of the relevant state standards.
Expansion of the use of final tailings of quartzite’s enrichment from Madneuli deposit for the manufacture of
heavy and aerated concrete is possible by activating the prepared raw mass produced on a shake table before
autoclaving.
For the final decision it is necessary to conduct big laboratory and industrial tests of concentration tailings
followed by the study of construction and technical properties and durability of the received wall materials.
