sulfuric acid has been considered an indicator of the condition of a nation's industrial activity (Sander and others, 1984, p. 261). The more sulfuric acid consumed, the greater the industrial activity and, thus, the more robust the economy. When considering the materials flow of any mineral, the global cycle must be considered.
