After a bauxite deposit has been discovered, the most appropriate mining method is selected based on technical, economic, and environmentally accountable considerations. The first step in selecting the most proper mining method is to compare the economic efficiency of extraction of the deposit by surface and uderground mining methods. Mechanical extraction methods employ mechanical processes in a dry environment to recover minerals, encompassing the specific mining methods of:
- open pit mining
- open cast mining
- quarrying of dimension stone
- highwall mining
Open pit and open cast methods employ a conventional mining cycle of operations to extract minerals:rock breakage is usually accomplished by drilling and blasting for consolidated materials and by ripping or direct removal by excavators for unconsolidated soil, followed by materials handling and transportation.
