Aiktinskoe and Bolaiktinskoe raw cement deposits

Aiktinskoe deposit of limestone and Bolaiktinskoe deposit of siltstone are located 24 km north-west of the Taksimo station. The deposits are developed for raw materials base for projected cement plant with a capacity of 2 mln. t. of cement per year. Nearby are located Zolotovskoe and  Kelyanskoe deposits of siltstone.

The Aiktinskoe and Bolaiktinskoe deposits' balance reserves of limestone and siltstone for portland cement production by dry -mix process for open mining were approved by the State Committee for mineral reserves of the USSR as of 01.06.1989 (minutes № 10703 of 30.08.1989, table 2.13.).

By the laboratory and technological tests of representative samples of limestone of Aiktinskoe deposit and of siltstones of Bolaiktinskoe deposit (Institute "Siberian Research Institute-projectcement") was proved the availability of portland cement brand "400" and "500" by dry-mix process and wet-mix process based on the 3-component blend (limestone - 73.3%, siltstone - 24.8% cinders - 1.9%).

Limestone of both deposits chemically complies with OST 21-27-76 "Сarbonate rock for the production of building lime", it is possible to obtain building lime I grade class A and B (GOST 9179-77). Limestone is also suitable for the production of mineral feed for farm animals and birds (OST 21-37-78).
