1 Froth Flotation – Fundamental Principles

(e) Enrichment Ratio is calculated directly from assays as c/f, weights are not involved in the calculation. Example Calculations: Problem: A copper ore initially contains 2.09% Cu. After carrying out a froth flotation separation, the products are as shown in Table 1. Using this data, calculate: (a) Ratio of concentration (b) % Metal Recovery

Chapter 2: Fundamentals of Isotope Geochemistry

An isotope enrichment factor, e, can be defined as: e p-s = (a - 1) · 1000 . (Eq. 2.9) If the reactant concentration is large and fractionations are small, e p-s ~ D = d p - d s (Eq. 2.10) where D (del) is another term for the enrichment factor. Note that Equations 2.8 - 2.10 for kinetic fractionations are the same as Equations 2.3, 2.6, and 2 ...
