Exergy cost allocation of by-products in the mining industry
In the mining and metallurgical industry, with each ore, products, by-products and wastes appear. Allocations among products when one or more by-products come about in a mining or metallurgical process are based either on tonnage or on commercial prices. Both ways of allocating costs entails disadvantages. My research proposed a rigorous way to allocate costs among non-fuel minerals through the exergy replacement costs. If exergy replacement cost is applied, cost allocation values are similar to those obtained via the price indicator. This supports the idea that the exergy replacement cost is very close to the value society places on minerals. |
