What is the profitability of an industrial plant? The investor is typically interested in the initial capex and a quick construction schedule to insure a quick loan repayment from the plant operating cost. The investors like to use a simple formula called a “payback time.” The investor is typically looking at a maximum of five‐year payback plan to repay the cost of the initial plant (capex) with the sale of the product, ore, or other merchandize and enjoy a loan and cost‐free life thereafter. Naturally, the economics are highly dependent on the commodity prices of the materials produced. Once the project is initiated, the cost estimate follows a more detailed approach.
