Limestone Mining, Industry, and Society | SpringerLink

Let us understand the marginal cost (MC) of production in limestone mining. The marginal cost of production is the change in the total cost that comes from making one additional item or producing one ton extra (i.e., increased output). The marginal cost of production includes all of the costs that vary with the level of production.
