ESG Opportunities for those who adopt the Kell Process

Energy efficiency: Among the most significant energy consuming activities in mining is beneficiation, such as smelting. In some cases companies who are considering implementing the use of the Kell Process technology in their operations observe  >80% less electricity required and approximately 50% reduction in energy usage compared with smelting. 

Air emissions: Conventional processing and recovery methods produce significant amounts of greenhouse gas emissions and in many cases also emit sulfur dioxide (acid rain) directly to the atmosphere. The Kell Process significantly reduces emissions of greenhouse gases, while eliminating noxious gas emissions entirely.

Water management: Mining companies give careful consideration to pollution prevention and water usage efficiency. The Kell Process targets re-use of water within the process wherever possible to lower water consumption.

The Kell Process is cyanide-free and mercury-free for gold recovery. Sulfur and arsenic are safely stabilised in residue storage as inert compounds.

Waste management: Mining operations generate process tailings, with smelting producing large slag stockpiles. Kell Process produces benign filtered and washed tailings residues suitable for dry stacking or co-mingling with flotation tailings.

Acid rock drainage (ARD):  Kell removes the constraints imposed on "smeltable concentrates" - allowing for higher recoveries of sulphur and base metals into concentrates. This reduces ARD potential in flotation tailings where Kell is implemented.
