GENERAL INFORMATION

The Akzhar-Sarytum field is located on the border of the Karaganda and Zhambyl regions, Ulkenzhol — in the Karaganda region. Both objects are located within the Akzhar-Sarytum synclinal structure extending to the west of Lake Balkhash. The nearest railway Saryshagan station is 47 km away from the first deposit, and 70 km from the second one. Another railway Kashkan-Teniz station is located 60 km southeast of the Akzhar-Sarytum field. A concrete highway is laid 3 km west of it. The high-voltage line VL-35 kV runs at the same distance.

HISTORY OF WORKS

After the completion of the first stage of exploration at the Akzhar Sarytuma site, C2 category reserves of 4,472.5 thousand tons of ore with an average manganese content of 22.55% were estimated and taken into account by the state balance sheet.

Additional geological exploration was carried out, which will allow clarifying the contours and other elements of the occurrence of ore bodies for the subsequent transfer of a significant part of the reserves to a higher category C1.

As part of the OPD, ~180 thousand m3 were mined and more than 3 thousand samples were taken, and the remaining ore reserves were formed. As of 01.01.2021 ore residues were formed in the amount of ~ 94 thousand tons.

The construction of a modular processing plant has begun, the expected launch date is the I quarter of 2024.

MANUFACTURING PROCESS

Brief description of the production process

The ore processing technology of the Akzhar-Sarytuma deposit provides for the enrichment
of ores by jigging to obtain conditioned concentrates of two types:

Fractions 10-50 — with Mn content of 36%;
Fractions 0-10 — with Mn content of 31%.

The main stages of processing Mn ore:

Reception

Crushing and screening in the crushing and screening module (DSM)

Crushing and screening in the crushing and screening module (DSM)
Wet classification, enrichment of a large class in a jigging machine, dehydration of concentrate, middlings and light fr. on screens in the coarse enrichment module (MCO).
Enrichment of a small class in a jigging machine, dehydration of a concentrate and light fr. on screens in the fine enrichment module (MMO).
Clarification of undersize waters.
Shipment of finished products.
