Flotation Material Balancing Excel Solver: Mass Balance

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

Metcom Expertise Metcom Technologies

As it turns out, a valid "mass-balance" formula can be derived from the following two questions: A. How much new product is being generated by the circuit? B. How much new product is generated by each pass through the ball mill? Then the circulating load ratio is equal to 'A' divided by 'B', the number of passes through the mill needed to

(PDF) Spreadsheet-based simulation of closed ball milling

Two of the three data sets were used to calibrate the ball mill and hydrocyclone models. At first step, measured data were adjusted using NOR-BAL 3 mass balancing and data reconciliation software (Spring, 1992). Then, using adjusted data the selection function of tube ball mills was estimated by NGOTC software (Farzanegan, 1998).
