Peter Simpson, of Peacocke & Simpson, in his role as the most experienced Knelson & Acacia commissioning and support engineer in Africa, recently assisted with the commissioning of two FLSmidth Knelson Concentrator XD20s and an Acacia CS500 intense leach reactor and electrowinning module.
The Knelson Concentrators are each rated at up to 80tph capacity and treat 100% of the mill circulating load. Project owners Roxgold took the decision to exert a high “gravity effort” in order to maximize gravity recovery from the high grade, high-GRG ore. The design specification for the process is 34tph ore running at 15g/t Au and up to 80% gravity gold.
The Knelsons and Acacia played a vital role in the process that led to Yaramoko’s 1,020 ounce first gold pour in Burkina Faso, and will continue to deliver for years to come.
Congratulations to Roxgold, who achieved this pour ahead of schedule, and just 13 months after breaking ground at the site. This is a fantastic achievement, and will put the company in good stead financially for future operations. Peacocke & Simpson looks forward to supporting the Yaramoko gravity circuit and to a long and fruitful relationship with Roxgold.
