Appropriate Process Technologies (APT) offers modular, off-the-shelf and custom-designed mineral processing plants suited to common mineral recovery processes, such as gravity concentration, leaching and flotation. The wide range of products are designed for recovery of everything from gold to lead, tungsten, chromite or tantalite, and allow for easy set up and installation.

The modular nature of the designs allows the logical progression of minerals process plants to suit changing ore conditions and cash flow generation. For example, a simple surface ore plant that uses washing or scrubbing of soft oxide rubbles or alluvial material for gold liberation and recovery by a FLSmidth Knelson Concentrator and shaking table can then be expanded and upgraded with the addition of an impact crushing module, for early liberation of coarse free gold hosted in quartz or other hard rock. This plant can then be further adapted by the addition of a formal milling section for liberation of finely-disseminated gold, and the FLSmidth Knelson Concentrator can be accompanied by an Acacia Reactor for intense leaching of concentrate that is no longer easily processed by shaking table. Further processes can then be added for non-gravity-recoverable gold, such as flotation of gold sulphides and/or gold leaching modules using APT Tritank technology.

Similar phased expansion and complexity is applied to other mineral products. Wherever possible APT’s shelf designs are used in various combinations to reduce lead time and process plant cost. However, even if a custom design is called for, APT prides itself on being able to deliver designs and equipment in record time.

In line with APT’s philosophy of appropriate technology, fast lead times and sharp pricing, pre-assembly and testing of minerals process plants in the APT workshop prior to packing and shipping allows for extremely fast erection on site, often allowing mines to be in production within days of arrival of the plant.

GCA is a corporate affiliate and registered agent of APT, supplying FLSmidth Knelson Concentrators, Acacia Reactors and shaking tables (GCA ST, Gemeni and FLSmidth) into APT plants, and providing support and service across the African Mining industry.
