Bauxite is generally extracted by open cast mining, being almost always found near the surface, with processes that vary slightly depending on the location. Before mining can commence the land needs to be cleared of timber and vegetation. Alongside this process may be the collection of seeds and/or saplings, for inclusion in a seedbank, which will form the basis of post-mining revegetation of
• Highwall/auger 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 and/or decomposed rock, followed by materials handling and transportation. Dimension stone quarrying is
Open pit mining While Sangarédi was the orebody on which CBG’s operations were founded, today between 85% and 90% of its output of raw bauxite comes from the Bidikoum and Silidara pits. After stripping any thin overburden, the ore is blasted and then loaded using hydraulic excavators into haul trucks for transport to the mine stockpiles.

Modelling open pit shovel-truck systems using the Machine Repair Model by A. Krause* and C. Musingwini† Synopsis Shovel-truck systems for loading and hauling material in open pit mines are now routinely analysed using simulation models or off-the-shelf simulation software packages, which can be very expensive for once-off or occasional use. The simulation models invariably produce different
Al Ba’itha is the only bauxite mine in the Middle East. It is an open pit mine with an annual capacity of over 4Mt of bauxite ore. The bauxite ore is refined in the GCC’s first alumina refinery at Ras Al Khair to produce 1.8 million tonnes of alumina per year, which is processed in the smelter to produce aluminium.
Mining leases and concessions are linked with rehabilitation conditions and the obligation to comply with government regulations. Many operations make rehabilitation the responsibility of individual production staff by including rehabilitation targets in their performance appraisals.
