The design calculation mass balance typically has few known values and many unknown values. These are typically encountered during plant design when the results of testwork and a flowsheet are the only known values. The purpose of a design mass balance is

Mass balance calculations can use the depiction of a flowsheet in two ways. Simple calculations should superimpose the calculation cells directly over the flowsheet, as in example calc #1. More complicated calcs should use the flowsheet to define stream numbers and then perform the computations in a table, as in example calc #2. Ball Mill

For a flotation circuit, material balance calculations define an engineering problem where flow parameters between unit operations are partly known. The purpose of a material balancing is to mathematically examine the known flow parameters to solve for the unknown flow parameters. Two main types of material balances are commonly made: design material balance operating plant material balance
