Automated Electronic Filter Design Scheme,A strategic question is often raised in connection with the evaluation of a deposit: What will the future demand for the metal (or metals) in the deposit under consideration be like? Does an analysis of the planned mining projects reveal shortfalls in satisfying demand?

Dealing with Data of Multi-Element Deposits,Generally speaking, multi-element deposits contain more than one metal as a significant source of revenue. This applies to most non-ferrous metal deposits. Complex volcanogenic sulphide deposits often contain five components: Cu, Pb, Zn, Ag, and Au. In this case, each individual component has to be weighted separately as shown in Sect.2.2.1.

Calculation of Cost Data,After having determined the capacity of the potential mine (Chap. 8), cost data will have to be calculated.

Economic Evaluations,Now that we know how to calculate the revenues (the net smelter return) for a potential mine from the grades of a deposit to be evaluated (Chap. 7); how to determine the life-time of a mine (Chap. 8); and how to derive capital and operating costs from the capacity (Chap. 9), we have all the data required to carry out economic calculations.
