CHONGQING GAOFENG NEW MATERIALS TECHNOLOGY CO., LTD.
Comprehensive Recycling Project of Red Mud
Red Mud (a by-product of Alumina refining of Wanbo Refinery) is used as raw material, mixed with Soda Ash and Limestone, to extract Sodium Aluminate Solution. The process comprises of grinding, calcining in rotary kiln and leaching. Sodium Aluminate Solution is transported to Wanbo Refinery to produce Alumina.
The project aims to achieve large-scale and high-efficiency extraction of valuable elements from Red Mud, with an annual output target of 4.385 million tons of Sodium Aluminate Solution.
The project site occupies 25 hectares, with fixed asset investment of USD 174 million, equipped with four lines of rotary calcine kilns and six leaching lines. After operation, the project expects to create output value of 208 million USD, tax revenue of 14 million USD and 400 new jobs.
