The clay plant at Bozshakol has seen a significant improvement in ore throughput in 2018.
The plant was shut down for its first major maintenance in the first quarter of 2018. During the closure, optimisation works were undertaken on the crusher to install wear resistant crusher parts and backup equipment. After completion of the optimisation works, the plant operated at an average of 109% of design ore throughput capacity over the second half of 2018.
In 2018, the clay plant increased the quantity of ore processed by 38% to 4.7 Mt (2017: 3.4 Mt), producing 13 kt of copper and 18 koz of gold.
Production was suspended for three months in the first half of 2019 to upgrade the water recycling system and reduce fresh water consumption.
