A Technoeconomic Comparison Of Three Process Routes For

Sphalerite is currently processed by crushing-milling-flotation, followed by the roast-leach-electrowinning RLE process. This route has major detrimental impacts on the environment, it produces SO2, and cannot treat ores of low grade or higher complexity. Therefore, alternative processes are being sought in order to circumvent the RLE process.
