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 (c) % Metal Loss (d) % Weight Recovery, or % Yield (e) Enrichment Ratio
When floating the flotation tails in the laboratory without any additional reagents, the recovery was seen to improve by an average of 5% while floating the tails with additional reagents improvements of up to 10% were observed (Figure 1). The higher the acid-soluble copper (AsCu) feed grade, the higher the observed improvement (Figure 2).
