The existing regrind circuit is limited to 5 tph and the overflow reports to the lowgrade leaching circuit, Ranford explained. This only provides for 35 percent of the gold to be recovered
processing cost is then equal to the value of the resulting mineral after processing minus the sales cost. Finding the OCOG is a bit more complicated because first, the opportunity cost of maintaining unexploited reserves has to be calculated, and then added to the processing cost. However, this value will automatically optimize the NPV and IRR.
The first process that most of the ores or minerals undergo after they leave any mine, is mineral processing or mineral/ ore dressing. It is a process of ore preparation, milling, and ore dressing
#0183;#32;Computer simulation is utilized to optimize coal preparation plant yields (Walters and Ramani, 1976; Abara and Gottfried, 1979). A circuit analysis approach is employed to analyze and op timize mineral processing circuits (Meloy, 1983).

Keywords : Circuit configuration; Circuit analysis; Optimization techniques 1. Introduction Mineral processing involves two basic steps: comminution and separation. In the comminution section, valuable minerals are liberated from gangue and at the separation stage, two products named concentrate and tailings are obtained. Various equipment is
One of the most important processing engineering tools for designing mineral processing facilities is linear circuit analysis. This technique, originally conceived and developed by Meloy, Williams

2 #0183;#32;Removal of the mineral matter (or ash), 3 which is largely noncombustible and may constitute up to 65 percent of the raw coal, increases the heating value of the coal on a mass basis. 4 Although some combustible material is lost as part of the cleaning process, the removal of unwanted material reduces the mass and volume of coal for a given heating value thereby reducing shipping costs
Coal cleaning does add additional cost to the coal price; however, among the several benefits of reducing the ash content are lower sulfur content; less ash to be disposed of; lower transportation costs, as more carbon and less ash is transported (coal cleaning is usually done at the mine and not the power plant); and increases in power plant peaking capacity, rated capacity, and availability
