Evraz PLC acquired a pilot plant and technology for tailings processing from Rock Capital Partners LLC for about 249.1 million Russian rubles.
Unit EVRAZ Kachkanarsky Ore Mining & Processing Plant only recovers about 20% of contained metals in titanium magnetite ores, and the plant can be used to process the tailings, Evraz said Oct. 18.
Evraz noted that the feed for the processing is free for the company given the existence of about 1.5 billion tonnes of Kachkanarsky Ore Mining & Processing Plant's tailings.
Rock Capital, controlled by major shareholders of Evraz, started up the pilot plant during the 2016-17 period for complex processing of tailings.
The pilot plant was to develop a technology for manufacturing products for the chemical industry by acid-using hydrometallurgical processing of the feed, but it was dismantled in January after a third party hosting the pilot production site in Russia declined to continue the experiments.
The plant was mainly producing magnesium sulfate, a coagulant using aluminum and iron sulfates, and complex alloy.
Evraz recently said it plans to lift annual capital expenditure to an average of US$1 billion from 2020 to 2023 as it seeks to increase sales of finished steel products.
As of Oct. 18, US$1 was equivalent to 64.03 Russian rubles.
