a) MASS BALANCE. The flow-rate of ore from your mine is 1000 t hr-1. This ore is crushed, and then milled. There is a single stage of milling, followed by a hydrocyclone. The hydrocyclone underflow is returned to the mill. 15% of the solids that leave the mill (and enter the hydrocyclone) go to the underflow and is recycled. Draw the flow diagram.

Mill flowsheet, sampling and Ni mass balance. A simplified format of Thompson Mill flowsheet is shown in Fig. 1. Two concentrates are produced in the Mill. The Cu cleaner concentrate is the only source of the Cu concentrate. The Ni concentrate is a combination of three streams, i.e., the Cu rougher tails, the Cu cleaner tails and the scavenger ...

A problem for solving mass balances in mineral processing plants is the calculation of circulating load in closed circuits. A family of possible methods to the resolution of this calculation is the iterative methods, consisting of a finite loop where each iteration the initial solution is refined in order to move closer to the exact solution.

Material balance calculations define an engineering problem where flow parameters between unit operations are partly known. The purpose of a material balance 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 and operating plant material balance. …
