Abstract

China is one of the most rapidly growing economies in the world and this growth is underpinned by growing demand for natural resources to meet base and precious metals and energy requirements. Even though China is currently the largest producer of several mined commodities, such as gold and the rare...

Even though China is currently the largest producer of several mined commodities, such as gold and the rare earth elements, meeting the future demands for metal consumption will require China to either develop new mining projects or increase material imports. In terms of nuclear energy requirements the country still depends on uranium imports. To meet this growth in Chinese demand, there has been a strong interest in technologies suited for mining and processing of low grade ore bodies. Percolation leaching methods have been very effective in extracting metals from low grade ores, which could not otherwise be economically extracted. Percolation leaching techniques, such as heap leaching, dump leaching, bio-leaching and in-situ leaching have been extensively employed in the Chinese mining industry in recent decades, primarily to extract gold, copper, rare earth elements and uranium.
