Mass and energy balancejoeperreau@aol The law of conservation of mass leads to what is called a mass or a material balance. Mass In = Mass Out + Mass Stored Raw Materials = Products + Wastes + Stored Materials. m R = m P + m W + m S (where (sigma) denotes the sum of all terms). m R = m R1 + m R2 + m R3

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 designedmass". This law states that matter is neither created nor destroyed in the process and the total mass remains unchanged. The general principle of material balance calculations is to put and solve a number of independent equations involve number of unknowns of compositions and mass flow rates of streams enter and leave the system or process.
