What is cyanide and why do we need cyanidefree gold leaching process? Cyanide (CN–) has been used since 1889 to recover gold from hard rock. As sodium cyanide (NaCN), it reacts with gold, oxygen (O), and water (H2O) to form a gold cyanide complex (Na
The i150 Gravity Concentrator is the smallest of the World famous iCONs. This is a gravimetric concentrator that uses enhanced gravity (G''s) to concentrate the ''free'' heavy minerals. It is also known as a centrifugal concentrator because of the centrifugal action of the spinning bowl. The process uses only water and an electric motor to concentrate the precious heavy minerals from a slurry.
Falcon has been involved with gravity concentration for the last years, having designed two distinct ranges of equipment; a semicontinuous Falcon SB range for installation into grinding circuits and the recently released Falcon C range for preconcentration and scavenging in a wide range of mineral industries.
