3.7 Example Mass Balance Calculations - Wills' Mineral Processing Technology, 8th Edition [Book] (3.36) In the above equation, i stands for an assayed metal and j for a process unit. The calculation of these best estimates requires the calculation of the derivatives of S for each of the unknowns, that is, the non-measured solid mass flowrates

Solving Mass Balances using Matrix Algebra
balance during a mineral processing plant design. Introduction Mass balance calculations describe an engineering problem where mass flows between unit operations and the composition of those flows are partly known and partly unknown. The purpose of the calculation is to mathematically analyse the known flows and compositions to solve for the
