SENET’s process expertise is underpinned by a formidable hydrometallurgical process engineering team – one of the largest teams in Africa. Over the last three decades, SENET has established itself as a leading supplier of copper and cobalt processing solutions to the mining and metals sector.
SENET has completed more copper-cobalt solvent extraction (SX) and electrowinning (EW) plants on the African Copperbelt than any of its competitors. In addition to its copper-cobalt expertise, SENET has a substantial gold processing offering, encompassing knowledge across various mainstream technologies that include, but not necessarily limited to, carbon-in-leach (CIL), carbon-in-pulp (CIP) and carbon-in-solution (CIS) gold extractive technologies.
SENET boasts specialist knowledge in the extraction of gold from more complex orebodies such as refractory and sulphide ores. To that end, SENET has undertaken conceptual designs in general concentrator plants, bacterial leaching plants, and ultrafine grinding in combination with atmospheric or pressure leaching, to name but a few.
SENET’s process engineering department is supported by a full-time metallurgical test work engineer to ensure designs are rigorously managed and verified through a metallurgical test work programme. The engineer manages the daily tracking and reporting of results, thus relieving SENET’s clients of having to deal directly with laboratories during studies and projects.
SENET’s process engineering department possesses the full commissioning skills and resources to ensure that all projects have a seamless interface between the construction and commissioning phases, according to specification and within safety parameters.

SENET has designed a number of plants using the standard froth flotation technology to produce saleable concentrates. Recent flotation reference projects include the Proyecto Rio Tinto for Atalaya Mining where SENET successfully recommissioned
the processing plant facilities, consisting of crushing, fine grinding, flotation and concentrate thickening. As a result of this success, SENET was awarded another contract: to increase the run-of-mine (ROM) ore throughput to 7.5 Mt/a.
SENET has extensive experience utilising the well-proven carbon-in-leach (CIL)/ carbon-in-pulp (CIP) process technologies to produce saleable gold bullion from the treatment of oxide and sulphide ores.
SENET has delivered more than 24 West African project studies and projects to date in this commodity alone, cementing the company’s reputation further on the continent.
In the early 1990s, SENET developed a range of proprietary heap leach stacking and agglomeration equipment that soon enjoyed global success. SENET quickly evolved from being more than an equipment supplier to emerge as a leading engineering, procurement and construction management (EPC/EPCM) contractor for entire heap leach plants.
SENET’s first major installation was in 1994, the 1.2 Mt/a plant at Cluff’s Ayanfuri gold mine in Ghana, which ranked as one of the first heap leach facilities to be provided by an African company. Today SENET is considered a world leader in heap leach equipment technology, and SENET’s heap leach expertise includes having engineered, constructed and commissioned more than 12 different projects to date.
The success achieved by SENET in heap leach technology has extended to other commodities such as copper and uranium, where SENET has a demonstrated track record. SENET has further cemented its reputation as by offering tailored engineering and construction solutions, specific to a client’s business needs.
