Bauxite is predominately mined by surface (open cast) mining methods and typically disturbs larger surface areas than underground or deep open pit mining. However, as the life of any given part of a bauxite mine is comparably short, rehabilitation may often commence more quickly after ore is removed compared to more traditional mining operations. For this reason, it is important that rehabilitation activities are integrated into the bauxite mine plan so that it is conducted as efficiently and effectively as possible.

Most of the world’s bauxite

Hengyang Company is mainly use underlist steps for bauxite mining:

1. Feeding
2. Crushing

3. Grinding
4. Mineral Dressing

5. Flotation

Mining Process

Bauxite is generally extracted by open cast mining, with methods varying depending on the location. A typical sequence involves:

• Clearing the land of vegetation and salvaging useful timber;

• Collecting seeds, where appropriate and feasible for use in revegetation;

• Removing topsoil (and sometimes subsoil) for use in rehabilitation, either by way of direct replacement on mined-out land or by stockpiling for future use;

• Removing the overburden (the layer between the soil and the bauxite);

• Excavation of the bauxite using mechanical methods or in some cases drill and blast;

• Once the bauxite is loosened, it is loaded into trucks or rail wagons or on to conveyors, and transported to a beneficiation plant (if processing is required) or to stockpiles;

• Beneficiation may improve ore quality and is a relatively simple process involving improving the bauxite grade through the removal of waste materials through screening, crushing, washing and dewatering. The process produces a higher-grade ore product and tailings (mainly clay and fine sands);

• Transporting the bauxite to alumina refineries.

• Once this removal is completed, rehabilitating the areas affected.
