1. Global material balance for iron Material flow information, of the type shown in below, typically comes from multiple sources, and material balances can be used to assess the consistency of the information. At the most macroscopic level, the basic material balance equation, in -out + accumulation, can be translated into crude ore in= flows to repositories + stock accumulation. Determine whether the flows in the figure below satisfy a material balance.
