The cost-to-profit graph for two mines using different types of copper extraction, smelting and bioleaching, is shown. Both mines are estimated to contain one million tons of copper. 900,000 800,000 700,000 600,000 500,000 400,000 300,000 200,000 100,000 0 Cost Cost to Profit Profit Key Smelting Bioleaching Based on the graph, which method of obtaining copper is likely the most cost-effective? A Using smelting has lower cleanup costs than bioleaching. Using smelting is cheaper and generates more profit than bioleaching. © Bioleaching harvests the copper in a shorter time period than smelting. ℗ Bioleaching is more expensive at first but the returns are much higher than smelting.
