| Summary: | RTB Bor is planning to expand the capacity of mining and processing at the Cementacija Kraku Bugaresku site from the current 2.5 million tons per year to 5.5 million. The current processing technology - the classic flotation of the entire excavated ore, without the separation of oxide and sulfide ores, due to the low copper recovery from oxide ore, has achieved the modest financial results. This article discusses an alternative method of copper obtaining using the hydrometallurgical heap leaching and SX / EW extraction method from leach solutions, in terms of economics, i.e. comparative analysis of cash flow and discounted cash flow for both cases (scenarios). The analysis is performed in a software for strategic planning and design in mining - Whittle Fx , with the input techno-economic data for both cases [7]. Due to the frequent breakdowns and causing the accidental situations on the current infrastructure installations of the processing plants, pipeline for pulp-hydro transport from the site to the flotation plant, in conclusion, to emphasize the comparative advantages of hydrometallurgical processing are emphasized in the conclusion not only in terms of the economy but also the environmental protection. In the world, the world's largest copper producers have a tendency to make, besides copper is necessary and valuable metal, also the 'green' metal. |
