+998 71 619 23 33On March 25 and 29 this year, the significant historical events took place at Almalyk mining and metallurgical complex. The hot start was carried out in the large crushing shop of the Copper concentrator plant-3 which processes the ore mined at the Yoshlik I mine.
The works began with a report from the head of the large crushing shop Bakhtiyor Eshboev who informed the Chief Engineer of AMMC Sergey Larionov that the shop was ready to receive ore. Then the information was passed on to the operator of the control panel of the ore receiving shop, and the unloading of ore delivered by quarry transport began. Ore from the Yoshlik I mine was fed into the receiving bins of the primary crushing plant, located directly at the mine. Each bin is designed for the simultaneous unloading of two quarry dump trucks.
Then the ore was crushed in cone crushers of the KKD-1500/200 (180)M-2P model to a fraction of 300–350 mm. Then the coarsely crushed raw material was sent along belt conveyors to two mainline conveyors with a length of 4,200 meters using six plate feeders. These conveyors, equipped with four 1,500 kW electric motors, transported ore at a speed of 4 m/sec and a capacity of 6,500 tons per hour from the Yoshlik I mine to the coarse ore warehouse, which holds 320 thousand tons. From there, the ore was sent to the dry enrichment section for further concentrator in accordance with the process regulations.
On March 29, the first concentrate was obtained at the Copper concentrator Plant-3 (CCP-3). The Chairman of Board of JSC Almalyk MMC Abdulla Khursanov and responsible persons of the plant took part in this historic event.
It should also be noted that the mine is nearing completion of the construction of two new structures – crushing and loading sets No. 1 and 2 which will soon be commissioned. This is where the process of the CCP-3 plant begins: ore of a fraction up to 1,500 mm undergoes primary crushing.
In order to minimize dusting and prevent environmental pollution during unloading of ore from quarry transport, a fully automated dust suppression system using water is installed at the complex. In the future, this solution will allow Yoshlik I to be classified as a "green mine".
Currently, the phased launch of production units, process lines and the automated control system of CCP-3 is underway.
