Innovations: How Hydrometallurgy and the

Beginning in the mid 1980s a new technology, commonly known as the leach-solvent extraction-electrowinning process or, SX/EW Process, was widely adopted. This new copper technology utilizes smelter acid to produce copper from oxidized ores and mine wastes. Today, worldwide, approximately 20% of all copper produced is produced by this is process.

Rare Earth Element Recovery from Acidic Extracts

One approach for extracting the REEs from phosphate mining materials is by leaching with different extraction liquids. Previous studies have used concentrated strong acids to extract REEs from phosphate mining materials; however, the use of concentrated strong mineral acids comes with economic and environmental drawbacks, including long reaction times often at elevated temperatures
