"As an accredited Knelson test facility we have been proudly associated with PS&A for since 1987. Over the years, PSA have successfully developed and executed many of the most advanced and metallurgically challenging gravity-based test programs on behalf of their clients. There is no doubt that many of these clients have realized significant positive financial benefits as a result of their practical and innovative approach."

“We have been impressed by the quality of service and dedication demonstrated by our gravity equipment vendors. They have been totally committed to getting the gravity equipment commissioned in a timely manner. Successful commissioning of the Knelson Concentrators and ACACIA Reactor has ensured our first gold production is on schedule”.

"In addition to its high throughput capability, low water requirement and outstanding gold recovery, the Knelson has performed excellently in terms of availability and maintenance requirements."

"We have selected Knelson as our primary gravity process at all operations processing ore which is amenable to gravity concentration." "We are very strong proponents of gravity concentration and have selected the Knelson Concentrator on the basis its efficiency to recover a significant portion of the overall gold into a very small high-grade concentrate mass." "We view the Knelson Concentrator as a simple, reliable and robust unit which compliments downstream recovery processes by producing low cost ounces right out of the grinding circuit where free milling gold if first liberated and available to be recovered," commenting on Ashanti's purchase of their 17th Knelson Concentrator.

"I would like to report that the 48 inch Knelson Concentrator is currently producing >50% of the gold at Target, this excludes the tailings from the Gemeni Table that we send to Rand Refinery. If the gold from the tailings is included, the figure is in excess of 55%."
