circuits at 6 different plants were carried out. The ball mills sampled in this study are ranging in diameters from 3.2 m to 4.8 m. Design and operational parameters of the ball mills sampled are given in Table 1. Table 1. Sampled ball mills design and operational parameters range Operating and Design Variables Values Mill diameter 3.2 4.8 m
The horizontal design allows the mill to start under load and translates to simpler maintenance. 8 Low Installation Cost Low height, small crane lifts and simple under-oor media system. Large scale mills and open circuit operation. This means less mills, less classication, simple circuit layout and lower installed cost. 9 Accurate Scale-up
The process design of gold leaching and carboninpulp gold plant will be that of the leaching and carboninpulp circuit CIP. The reagent and utilities operating costs associated with leaching adsorption elution and regeneration would typically make up some 15 of total operating cost whilst the capital costs associated with these areas is about ...
Another significant aspect is the controllable speed. Due to the higher capital costs for ring motor drives, they are generally only used if very high drive powers are required. Shell supported ball mills are ideal for the use of ring motor drives 3 Because of the high rigidity of the mill shell, troublefree transmission of the magnetic forces is

characteristics. This resulted in a very complex process plant design. The final design had a capital cost of approximately 200M. The scope of this current estimate was restricted to the Kundip resource and considered just two metallurgical domains the low copper oxide and the high copper sulphide. This greatly simplifies the process design.
The indirect cost was estimated at 45 of direct capital costs and was considered to be within industry standards for the options considered. A similar approach was applied to estimate the total direct costs. It was found that both HPGR-ball mill and HPGR-stirred mill circuits have higher associated capital costs than the SABC option.
