In subSaharan Africa, Fluor has applied its modular approach to design 60 process plant modules and 106 conveyor and services gantry modules for Debswana's Letlhakane Mine Tailings Resource Treatment Project (LMTRTP) in Botswana. The design of the modules was tailored specifically around the project size, loion and client requirement.

CBG is considering increasing its bauxite production capacity from million tonnes per year (MTPA) of shipped material to MTPA (at 3% moisture content) by the last quarter of 2017, followed by another 5 MTPA increase to reach a capacity of MTPA around 2022.

Cape Crushing Earthmoving The new plant had to integrate with the existing Nammuldi operations and be installed and commissioned within approximately 12 weeks. Process 26 successfully designed, procured and constructed a 300m tail driven conveyor within this short period.

crushed, stockpiled, and dried as necessary before loading to ships for export. One calcining kiln for production of high value calcined bauxite will be built at the outset and a second one provided later. Locomotives and rolling stock for transporting the ore to Kamsar, and loading equipment at the pier, will be provided by CBG.

 · Crushing Calcite Ore: In the flowsheet a 2stage open circuit crushing section is provided to reduce the limerock to approximately minus ¾" for feed to the ball mill. The size of the crushing equipment depends largely upon the quarrying operation and the size of the largest pieces delivered to the crusher.

CBG also exports low monohydrate and small amounts of calcined bauxite and imports all its fuel and equipment spares through its own port facilities. The largest single producer of bauxite (aluminium ore) in the world Cie des Bauxites de Guinées (CBG) operations are loed in the west of Guinea close to the border with GuineaBissau.

The number of crushing steps necessary to reduce ore to the proper size vary with the type of ore. Hard ores, including some copper, gold, iron, and molybdenum ores, may require as much as a tertiary crushing. Softer ores, such as some uranium, bauxite, and titanium/zirconium ores, require little or no crushing.

Bauxite occurs mainly in tropical and subtropical areas, like Africa, the Caribbean, South America and Australia. Australia is the largest producer of bauxite, with five large mines supplying around 30 per cent of global production. Bauxite mining has five steps: preparation of the mining area; bauxite mining; crushing;

 · Crushing Equipment. Primary Crushers – Jaw and Gyratory. Within the crushing circuit, a primary crusher reduces material down to a size that can be conveyed and fed to the secondary crushing circuit. The two most common primary crushers used for coarse runofmine material are the jaw and gyratory crushers.
