Knelson Gravity Solutions

The ConSep ACACIA Reactor has achieved excellent production results from real installations in large gold plants.

Actual production results from installations of the ConSep ACACIA Reactor have seen gravity recoveries increase by over 50% compared to previous concentrate treatment methods.

Bill Lethlean - Anglogold Chief Metallurgist Engineer - "There has been a plus 20% increase in gold recovered by gravity circuit since the installation of the ACACIA Reactor. The major impact within the gold room has been the elimination of health issues due to arsenic oxide fumes generated when treating Gemini table concentrate and improved security with respect to manually handling of high grade gold concentrates. Another improvement has been a stabilizing of the CIL recovered gold and reducing the overload situation developed in the CIL/Elution circuit due to the increasing tonnage throughput." - Testimonials

The advantages of this process and numerous design features all contribute to increase recoveries, mechanical reliability and operator safety.

Process

Engineering

Increased gravity gold recovery
Recover gravity gold as an electrowin product
Allow daily accounting of gravity concentrate
Increased security and safety mechanisms
Reduction of loaded carbon elutions by reducing the grade to the CIL circuit
Reduction of potential for gravity gold to report to CIL tail
Reduction of gold content in the comminution circulating load.
Eliminates OH&S problems associated with calcining gravity concentrate containing sulphides (especially arsenopyrite)

Batch system process to eliminate short circuiting issues
Fully automated design eliminates operator involvement
Minimal moving parts and no special guarding requirements
Vent lines are built into the tanks sealed lids to maximize operator safety.
Supplied as a modular self-contained unit or integrated into your gold room.
Designed for minimum inventory of pregnant solution within the system
