Tschudi project has a life of 11 years from the commenc ement of processing. Using the mining rates quoted by the preferred mining contractor the contract mining cost wil l average USD2.26 per tonne for the first five years. The output from the Tschudi project will be copper cathodes a final product 99.99 pure copper sheet.
Ore processing will consist of crushing grinding conventional flotation and thickening and filtration. A semi-autogenous grinding mill and ball mill will be used to reduce crushed ore to the designed particle size for the copper and zinc flotation circuits. The flotation circuits will require the addition of

The Kalahari Copper Belt Project is situated within the Arid Fertile Savannah Vegetation type with elevation averaging between 900 and 1000 m above sea-level Figure 7-3. Figure 7-3 Regional vegetation map of the Kalahari Copper Belt project. 7.1.6 Climate The Kalahari Copper Belt Project is situated in an area that averages between 300
Ore is treated using a two-stage crushing process followed by a two-stage grinding circuit that consists of a semi-autogenous grinding mill and a ball mill. Most of the ground ore is fed to a gravity circuit that recovers about two-thirds of the gold which is then smelted on site to form dor bars.
Apr 03 2014 Fig 1 A typical flow sheet of iron ore beneficiation plant. Some of the common methodstechniques applicable for iron ore processing are described below. Crushing grinding and screening technique. The purpose of grinding and regrinding is to reduce the ore to a size small enough to liberate and recover the valuable minerals.
Summary Mines are faced with numerous challenges such as falling raw material prices declining metal grades in the ores and higher energy prices. Especially because ore processing is particularly energy-intensive the industry is again focusing on the saving of energy. This report shows what are the key energy saving considerations in the copper and gold mining sectors.

The barren rock or gangue has to be separated from the sulfide minerals in order to smelt the metallic copper from the ore. By far the greatest proportion of copper is extracted from the sulfides of copper iron and sometimes other metals. Such ores originate from sulfur-bearing volcanic magmas which have separated into metal sulfides and siliceous melts.
