Stripping operations at the deposit are performed by a bulldozer.

The overburden is removed for reclamation of mined-out areas.

The thickness of the productive layer is visible along the edge of the quarry.

The productive layer is developed in two benches.

Carbonate raw materials are transported to three process lines, where they are sorted and crushed to a flour state.

Feeder hopper of the crushing and screening plant, equipped with a grate.

From the bunker, the raw material goes to the vibrating screen, where particles less than 5 mm are sifted into finished products.

Larger particles go to the hammer crusher.

After the crusher, the particles go to the second screen.

Sorting is repeated.

The second line operates in a similar way.

Third line.

From the feeder bunker, the raw material goes to the jaw crusher.

After the crusher, the crushed mass goes to the screen, where it is sorted into waste and finished products.

After crushing, the rock, together with some of it that has fallen through the blast furnaces, is fed via a conveyor to a vibrating double-grate screen.

The material that has passed through the lower sieve with 5x5 mm cells is fed to the finished product warehouse.

The remaining raw materials are fed to a secondary crushing hammer crusher.

After the hammer crusher, the finished product is delivered to the warehouse.
