It is more than just a flowsheet/design package. It's a Windows-based system that allows Solvay to design solvent extraction circuits on demand. Using information from mining companies or their engineering firms, we are able to evaluate circuit configurations, flows, extractant performance, and recovery options. Using computer software programs for process optimization is nothing new to many industries, and it's not new to SX/EW. But Solvay’s proprietary MINCHEM application remains the SX industry's first and most sophisticated modeling tool.
