Coal, electricity and aluminum integration project of Wachangping bauxite mine for State Power Investment Corporation Limited, Zunyi, Guizhou.

Coal, electricity and aluminum integration project of Wachangping bauxite mine for State Power Investment Corporation Limited, Zunyi, Guizhou.

The project is the first metal mine to adopt the longwall comprehensive mechanized mining technology. It has formed a production capacity of 3,000 t/d bauxite by “one shaft，one face and one set” of integrated mining equipment. It successfully solved problems and technological difficulties of roof corrosion development, water filling, safety, high-efficiency and low dilution loss of unstable and gentle-inclined thin-medium thick difficult-mining orebody, which adds a new mining technique for metal mining.

Laohudong Phosphate Mine Project of Weng 'an County Tianyi Mining Co., Ltd.

Laohudong Phosphate Mine Project of Weng 'an County Tianyi Mining Co., Ltd.

The designed mining and beneficiation capacity is 5,000kt/a. It is the single largest underground phosphate mine in China's chemical industry. New technologies of skip-shaft and auxiliary shaft development and transportation, upward horizontal slicing and filling mining method and upward drift filling mining method, self-gelling hemihydrate phosphogypsum plus tailings paste filling method and so on, are firstly adopted in the chemical mine to realize large-scale safe and efficient mining, which provides a new idea for phosphate mining.

Boffa Bauxite Project

Boffa Bauxite Project

The production capacity of the first phase is 12 million t/a. It is the “No. 1 Project” of Chinalco's “Two-sea Strategy” to build a bauxite overseas base and the first time to develop the high-efficient and green mining technology of low-latitude leaching residual bauxite. The design adopts the world advanced green and environmentally friendly open-pit mining technology that integrates mining, crushing and loading, the 24km large-scale, long-distance and high-speed cross-country belt conveying technology and the super-large advanced equipment. The project started in Oct., 2018, was put into production in Apr., 2020 and reached ramp-up and the standard in Jun., 2020.
