total mass (m). When the sink is described in this first order form we can rewrite the mass balance as: d[M] / dt = Q k [M] At steady state, when d[M] / dt = 0, [M] / Q = mass present/input = 1/k = This equation predicts an inverse relationship between elemental reactivity (k) and residence time as k

All metallurgical accounts are wrong, it is just that some are more wrong than they need be! · Concentrate production from mineral concentration processes (flotation, dense medium etc) can be calculated in different ways which each give a different answer. Conventionally, one method is taken as “the best” and is used to prepare the accounts,

Solving gives A=126.8 lbs/hr, B=591.6 lbs/hr, and C=281.6 lbs/hr. Simple! Note that the fourth possible mass balance equation on the total flows, A+B+C = 1000 lbs/hours, is satisfied as expected for this dependent relationship and provides no additional information. That is the total mass in equals that out, as expected at steady state. BACK TO LECTURE NOTES
