number of grinding lines and capital cost vis à vis the use of HPGR and intended pre-crushing. In general, for high-aspect mills, higher ratios of DL permit operation at higher mill speeds for a given rated power output. Lower ratios of DL have been frequently rated at 72% C.S. to 74% C.S. but, as will be seen in Figure 2, there is an advantage to be gained in raising the rated power output

Process Equipment Cost Estimating by Ratio and Proportion

Regardless of accuracy, capital cost estimates are typically made-up of direct and indirect costs. Indirect costs consist of project services, such as overhead and profit, and engineering and administrative fees. Direct costs are construction items for the project and include property, equipment, and materials. This course deals with the equipment component of direct cost.

Abstract USGS

Working capital, based on 2 months of operating costs, was included in the capital cost of each mine and mill model. Working capital covers the cost of meeting operating costs in the initial stages of production, before revenue is generated from the first shipments of product (concentrates or dote). This value can vary from. 2 to 6 months
