Calculation of the Initial Capital Outlay for Lead and Zinc Processing Plants

Abstract

Calculation of the initial capital is one of the primary requirements in the feasibility study of industrial projects. In this paper a typical processing plant has been designed for the feed capacity of 500 to 8000 tons per day in sixteen different steps. A mathematical model in the shape of Y=exp(a+b.Ln(X)) has then been devised that calculates the cost of some of the machines used in these different capacity plants. In all these models Y is the capital cost and X is the most important variable in choosing the machinery. The total capital cost of all these different capacity plants have been calculated by the addition of construction make, building etc to the results obtained from these models. A mathematical model is then introduced that calculates the total initial capital requirement for sixteen different capacity lead and zinc processing plants. The methods adopted and the models introduced could be used in the design process of such plants and to evaluate the feasibility of such project.
