KTI erects a jumbo ice plant at Harmony’s Phakisa gold mine in only ten days09 July 2014
KTI was selected by Harmony Gold Mining Company Limited to supply and install an ice cooling system at Harmony’s Phakisa gold mine in South Africa. Harmony is one of the largest gold producers in the world, generating annual revenues of US$1.8billion.
Underground mines with depths reaching more than 2400 meters below surface, require extensive cooling to reduce the rock temperatures to less than 28°C. Adequately cooled air is essential for compliance with health and safety regulations, which also increases the productivity rate and reduces the injury rate.
Phakisa gold mine has been using underground water chillers for bulk air cooling, as well as a 2000 tons per day surface ice plant for cooling of underground service water and for localised coolers closer to the working areas.
KTI introduces a paradigm shift in the application of surface ice making for deep-mine refrigeration and cooling, with each plant producing 220 tons of ice with a 27°C water in-feed. The capital cost of an ice plant is below R9000 per kilowatt, which is lower than alternative cooling means.
The system installed at Phakisa is a breakthrough in terms of modular containerized ice making systems. As cooling demand underground increases, the system ensures swift installation and easy expansion. In addition, should it be required, these units can easily be moved to another location.
After witnessing the successful operation of first 2 KTI Ice Plant, Harmoney has ordered 4 more plants. These new plant will also consists improved Water Chiller.
