San Diego Mining Company (SMC) mines coal, puts it through a one-step crushing process, and loads the bulk raw coal onto river barges for shipment to customers. SMC's management is currently evaluating the possibility of further processing the raw coal by sizing and cleaning it and selling it to an expanded set of customers at higher prices. The option of building a new sizing and cleaning plant is ruled out as being fintancially infeasible. Instead, Amy Kimbell, a mining engineer, is asked to explore outside-contracting arrangements for the cleaning and sizing process. Kimbell puts together the following summary: (Click the icon to view the summary.) (C) (Click the icon to view additional information.) Read the requirements. Requirement 1. Prepare an analysis to show whether it is more profitable for SMC to continue selling raw bulk coal or to process it further through sizing and cleaning. (Ignore coal fines in your analysis.) Begin by calculating the incremental sales revenue, then incremental costs and finally incremental gain or loss. (Do not round until the final answer for each cost calculation, then round to the nearest dollar. Use parentheses or a minus sign for losses.) Incremental sales revenues: Sales revenue after further processing Sales revenue from bulk raw coal Incremental sales revenue Data table More info 3. (Do not round until the final answer Kimbell also learns that 75% of the material waste that occurs in the cleaning and sizing process can be salvaged as coal fines, which can be sold to steel manufacturers for their furnaces. The sale of coal fines is erratic. The selling price of coal fines ranges from $15 to $23 per ton, and costs of preparing coal fines for sale range from $2 to $4 per ton. Requirements 1. Prepare an analysis to show whether it is more profitable for SMC to continue selling raw bulk coal or to process it further through sizing and cleaning. (Ignore coal fines in your analysis.) 2. How would your analysis be affected if the cost of producing raw coal could be held down to $18 per ton? 3. Now consider the potential value of the coal fines and prepare an addendum that shows how their value affects the results of your analysis prepared in requirement 1
