Mass Balancing of Concentrator Data Outotec
Mass balancing can be done for all process types covering laboratory tests, pilot plant runs and full scale mineral beneficiation plants In this example the Vammala gold ore flotation plant in southern Finland was sampled for the circuit balance and recovery calculationMass balancing is a common practice in metallurgy The mass balance of a circuit is needed for several reasons: 1) To estimate the metallurgical performance of the circuit 2) To locate process bottlenecks and for circuit diagnosis 3) To create models of the processing stagesMASS BALANCING AND DATA RECONCILIATIONAbstract 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, particlesize analyses, global chemical analyses and, simultaneously, chemical analyses within particlesize classesMass balance calculations around mineral processing units
Lecture 11: Material balance in mineral processing
Materials balance Water balance (dilution ratio) Illustration Conclusion References Key words: Material balance, ball mill, hydro cyclone, flotation Preamble An important aspect of any mineral processing study is an analysis of how material is distributed whenever streams split and combine This knowledge is necessary when a flow sheet is The mass balance will be solved using the matrix algebra formula for the regression equation: w=AT⋅A−1⋅AT⋅ywhere w is the vector of unknowns, Ais the matrix of equations and yis the vector of known values1Solving Mass Balances using Matrix Algebra An approach for flowsheet mass balancing in the presence of PO of SCs is proposed The maximum numbers of MCs that still permit MB have been determined for single and multinode flowsheets If the number of MCs exceeds the maximum value, the observed data do not carry sufficient information to generate a flowsheet MB Naturally, as the number of MCs approaches the maximum Flowsheet mass balance with partial observation of stream
