Copper-Arsenic Processing
CESL has developed a process for treating high arsenic bearing copper-sulphide resources from mine-to-metal while producing non-hazardous arsenic bearing residues.
CESL Projects
The first commercial hydrometallurgical facility using CESL Technology was constructed by Vale in the Carajás region of Brazil in 2008.
Metallurgical Testing
CESL’s facilities have a substantial amount of hydrometallurgical equipment for the testing of various processes and flowsheets, including grinding, flotation, pressure leaching, solvent extraction, gravity concentration and electrowinning. In addition to equipment, CESL has its own analytical laboratory to support testing programs, an on-site maintenance and instrumentation team, and a robust safety program.
