Mass Balancing or Material Balance in Mineral processing ...

Material in a mineral processing environment can be classified as either solid mass or solution mass or a combination of the two. At its simplest a material balance reflects an inflow and out flow of materials for a unit, circuit or overall process. When the inventory of the given unit equals zero the inflows must equal the outflows. What is mass balance in mineral processing? In

Leveraging accuracy and precision - multi-phase mass ...

01/01/2005  Simultaneous mass-balancing of a mineral processing flow sheet results in adjustments to each data point that reflects the accuracy and precision across the full set of data. In this way, all the good work that goes into designing the sampling and analysis protocol for each sample point is leveraged in order to produce a 'better' set of balanced numbers for every sample point in the circuit.

01/08/1987  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. The method which is developed is based on a suboptimal approximation of a weighted least-squares procedure where the mass

Mass Balancing - an overview ScienceDirect Topics

Mass balancing is important in not only assessing the accuracy of XRD and mineral analysis but also evaluating the suitability of ores for upgrading and beneficiation. The bulk chemical composition is calculated from the XRD and mineral analyses (by microprobe or SEM analysis) and is compared with the actual chemical analysis (by XRF or ICP analysis). This shows the contribution that each mineral
