Metal prices as a function of ore grade - Science Direct

We therefore propose to establish a relationship between market price and the cost of finding, mining and refining the metal. The actual variables we shall use will be crustal abundance of the metal, the average ore grade and the Gibbs free energy of the ore mineral. We assume that the latter is related to the cost of the plant.
