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

Two main types of material balances are commonly made: design material balance; operating plant material balance The design material balance is typically faced during plant design when the flotation test work results and a flowsheet diagram are the only known values Design material balance purpose is to find values for the unknown flow parameters

By referring to the tables “Minerals and Their Characteristics” (pages 332-339) it is seen that the perfect grade of a copper concentrate will be 633% when the copper is in the form of bornite, 798% when in the mineral chalcocite, and 346% when in the mineral chalcopyrite

This paper proposes an extension to an already available mass balance algorithm for mineral processing data A typical set of data which can be processed by the proposed method contains flowrates measurement, particle-size analyses, global chemical analyses and, simultaneously, chemical analyses within particle-size classes

parameters to solve for the unknown flow parameters Two main types of material balances are commonly made: design material balance and operating plant material balance

In this metallurgical (material/MatBal balance) involving 2 concentrates or 3 products, we have this example: It is decided to take a copper tail (zinc feed) sample in order to provide a check on the results calculated in the previous example

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 unknown flows and compositions Two main types of
