For doing so, mining companies extract resources from mineral deposits around the globe and use different techniques to recover the valuable mineral resources from the ore. The choice of a suitable technique, which is both environmentally sound and economically
Sep 22, 2004 Abstract. This white paper summarizes the state of art of in-situ leaching of metals and minerals, and describes a new technology concept employing improved fragmentation of ores underground in order to prepare the ore for more efficient in-situ leaching, combined with technology to continuously improve solution flow patterns through the ore during the leaching process.
are more energy efficient. Reverberatroy furnaces also produce large volumes of low concentration SO2 gas, which is difficult to use in sulfur recovery. The gases produced by electric smelting are smaller in volume, lower in dust less than one percent and have a higher SO2 concentration, which allows better sulfur recovery in an acid plant.
