  • Mining and Refining – Rehabilitation

    Specific rehabilitation processes are very much dependent on the mine site and the ecological, social and geological conditions. A general process involves first landscaping the mined area to reshape the pit, burying large rocks and removing pit faces. Operators take the opportunity to improve drainage; heavy vehicles used during the mining process can compact the ground, making it difficult for roots and water to penetrate. Mechanical ripping

    Newmont has completed two significant rehabilitation projects: filling in the mine’s pit and covering the land with native grass and tree species, which was completed in 2005; and transferring 480,000m 3 of soil to the dam’s tailings sites to prevent harmful materials from seeping into local waterways. The land excavated to provide this soil will then be turned into a wetland, an option preferred by local
