ENVEX is focused on low-cost recovery of metal value from calcine tailings, metallurgical residues, effluents and spent catalysts. The company employs novel hydrometallurgical technologies under exclusive license from IPEX for:
Cost-effective recovery of vanadium from current and discontinued calcine tailings facilities, process effluents, contaminated groundwaters, spent catalysts, fly ash, etc.
Production of various metal salts employing selective leaching and ion exchange purification techniques
Conversion of recovered salts into high-purity compounds including sodium ammonium vanadate, potvan (KVO₃), vanadium oxalate, vanadyl sulphate/chloride (VRB electrolyte), base metal sulphates/hydroxides and others
The technology finds application in recovery of a range of valuable metals (Cu, Co, Zn, Pb, Ni, Li, Mo, etc...)
