GPK “Karatau” and GPK “Chulaktau” branches are mining and processing complexes for extraction and processing of phosphate rock, the probable reserves of which are more than 13 bln. tons. The deposits are located in Zhambyl and partially in Shymkent oblasts in the south of Kazakhstan. These reserves are mainly concentrated in 6 biggest deposits of the basin and make 1/3 of explored phosphate rock reserves on CIS territory and about 5% of explored world reserves.

The branches include 6 deposits of open-cast and underground mining of phosphate rock, 5 grinding-sorting and processing factories for initial treatment and final output (phosphate powder, lumpy phosphorite, phosphate fines, phosphate-siliceous raw material). Mining and production of rock with low As content was settled.

Rock is treated at processing factories with high capacity and modern equipment as KKD-1200/180, KSD-2200, KMD-2200 crushers, GIL-52 screens, Czech dry milling mills 4,4 x 15 meters in size.

These facilities provide with production of:

• phosphate powder for extraction;
• phosphate fines for electrothermics;
• associated production of dolomites, limestone, silica, marble breccias, marble aggregate.

The abovementioned products are exported as well as sold to the Kazakhstan market.
