Question ? (10) points a) A 100 d copper ore processing plant is working to produce copper concentrate at a yield of 55% from the fed ore on weight bases. The copper enrichment ratio in the plant is 1.68. You are required to answer the following questions and clearly show all calculations- Calculate the copper recovery in the concentrate fraction and its reject m the tail fraction (2 points) Calemate the ratio of concentration for copper in this plant (2 points) Calculate the copper assay in tailings if the copper assay in feed is 1.25% (2 points) Question ?
