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 being.
Mass and balance theory • definition: • mass: the amount of an item inside a body • center of gravity (c.g): the point through which the force of gravity is said to act on a mass. • balance of arm (ba): the distance from the datum to the centre of gravity of a mass • moment: the product of the mass and the balance arm = mass * arm.

The state of a process can be described from a collection of data: flow-rate values, particle-size distributions and chemical compositions of the various streams of the circuit studied.however, the obtained raw data are generally redundant and inconsistent from a material balance viewpoint, due to natural disturbances, sampling errors.
The “mass balance” is unquestionably the most common class of problems for the process engineer. closely related, mathematically, is the “heat balance”. every laboratory test requires a mass balance to describe the results. mass balance calculations can be subdivided into several sub-categories based on whether the results are time dependant or not and depending on whether the input.
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.
