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 mans found nearly 100 lens-shaped ore bodies in the Rio Tinto copper district. Modern geologists have found only a few additional deposits, and almost all of Rio Tintos modern production has been from ore first discovered by the Remans.3 At Rio Tinto, the Remans mined the upper, ox-idized, part of the ore and collected the copper- Sep 03, 2020 Copper-molybdenum ore beneficiation Molybdenum is an element with relatively small reserves and relatively dispersed distribution in nature, and its content in the crust only accounts for 0.001%. Currently, more than 20 molybdenum minerals have been identified.
