The mineral processing techniques on sulfide tailings reprocessing can have advantages as follows: (1) enhance the recovery efficiency and grade with relatively low capital and operation cost, (2) reduce tailings volume and environmental effect, (3) easy process operation, and (4) easy modification and expansion for existing operation.
Future copper needs and hence, mining activities will determine the future availability of copper tailings and reprocessing potential. Three scenarios for 2050 are explored based on projected, prospective dynamic material flow analysis linked with resource scenarios of the previous studies by Ciacci et al. (2020) and Elshkaki et al. (2018).

The mining process is relatively simple and does not require deep excavation or blasting. Main process: Due to its fine particle size and high density, sand chrome ore mainly uses gravity separation methods, such as shaking tables, jigs, spiral processes and other equipment to achieve the separation of chromite from gangue minerals.
Tailings disposal has attracted extensive attention all over the world in recent years. With the rapid population growth and economic development, the demand for mineral resources is also increasing [1, 2].Therefore, ores are decreasing year by year, whereas the production of the mining industry has resulted in a large number of tailings, which are stored in tailings ponds for …
- **Tailings Volume Reduction**: Reprocessing of tailings can also reduce the overall volume of waste material, which may include the removal of carbonate minerals as part of the process. While reprocessing can generate economic benefits, it is important to assess how the removal of carbonate minerals might affect the long-term stability and ...
