At Peacocke & Simpson, we place emphasis on gravity recovery. In addition to being more environmentally friendly and sustainable, gravity recovery is also more economical than applying costly chemistry to the mineral recovery process. As such, Peacocke & Simpson is committed to the environment and to helping our valued clients achieve higher yields at less cost.
chemical recovery
When chemical recovery is necessary, we pride ourselves in having state of the art equipment and expertise to conduct leaching, flotation and other chemical testing and process testing procedures to the highest quality. This is either done independently, in comparison with gravity recovery, or as a peripheral or downstream process with gravity recovery, depending on the needs of each individual client.
equipment
We are proudly associated with FLSmidth (Knelson Technologies) – acknowledged world leader in enhanced gravity recovery equipment – and provide valuable R&D services to the company, in addition to being the trusted testwork partner of APT (Appropriate Process Technologies), ConSep and Rocklabs.
enhancement
Peacocke & Simpson is committed to the continuous enhancement of mineral processing solutions and the development of the mining industry not only in Africa, but throughout the world.
