Utilization of Coal Consumption and Processing Waste in Aluminum Production

The aluminum content in coal wastes in the Kemerovo region of the Kuznetsk Basin is investigated. The possibility of using such waste to extract aluminum concentrate by acidic leaching using sulfuric acid and nitric acid is assessed. Complete aluminum extraction in one processing cycle is impossible...

Description
Summary:The aluminum content in coal wastes in the Kemerovo region of the Kuznetsk Basin is investigated. The possibility of using such waste to extract aluminum concentrate by acidic leaching using sulfuric acid and nitric acid is assessed. Complete aluminum extraction in one processing cycle is impossible, but around 96% extraction is possible by successive leaching. The content of aluminum oxide in the concentrate is 84.5%.
