As a partner of choice in minerals processing, since 1984, we have successfully completed over 300 projects, in 26 countries. Our extensive experience comprises all fields of engineering – electrical and instrumentation, process, mechanical, civil and structural, infrastructure – as well as materials handling.
We deliver mineral processing plants that meet world-class standards and exceed client expectations. All our projects, their surrounding infrastructure and materials handling functions, operate in line with the highest quality standards, systems and procedures (ISO-based) and every project is managed according to the highest safety standards.
Through the diverse skills of our process engineering team, we offer comprehensive skills in all minerals recovery processes, such as coal and diamond dense media separation (DMS), comminution, flotation, gold recovery, gravity separation processes, SX/EW and pyrometallurgy.
Our processing experience includes crushing circuits, ore stockpiling and reclaim systems, pre-concentration, milling circuits, flotation plants, solids dewatering, dryers, roasting and smelting, leaching, bio-leaching, absorption and elution circuits, gold refining, DMS plants, gravity concentration, diamond concentrate handling and final recovery, high intensity magnetic and electrostatic separation techniques, slurry pumping and tailings disposal systems and laboratory design and equipping.
Due to our well-established relationships with equipment suppliers and commercial laboratories worldwide, we are able to provide clients with optimal and cost efficient process designs.
Location: South Africa
We were contracted to manage and design of the Khumani Iron Ore Greenfields Project in South Africa. The project was delivered ahead of time and under budget and resulted in a brownfields expansion. Our specialised project team was tasked as the lead contractor for end-to-end project management and integration of the crushing facility, processing plant, stockyards and infrastructure during the construction phase. Due to this highly successful implementation, we were contracted to manage various other phases of the project, including the EPCM contract for a super fines beneficiation plant in 2011. This plant uses WHIMS technology to process -1 mm super fines for the extraction of saleable product.
Client: Randgold Resources and AngloGold Ashanti
We expertly managed the EPCM contract for the Kibali Gold mine, located in the Democratic Republic of the Congo (DRC), for RandGold Resources, AngloGold Ashanti, SOKIMO. Our team delivered the design, procurement and project management of the metallurgical plant, infrastructure, a 45 MW backup power system, tailings system for a 6.1 Mt lined concentrate tailings dam and 7.6 Mt float tailings dam. Our scope of work on the processing plant included the design and construction of a facility to treat 3.6 Mtpa of oxide ore through the oxide circuit, and 3.6 Mtpa plant for the treatment of sulphide ore through the sulphide circuit. The project deadline was brought forward, but we rose to the challenge and first gold was poured a month ahead of schedule.
Renard Diamond Project
Client: Stornoway Diamonds
Our team of experts was contracted by Stornoway Diamonds to provide engineering, detailed design and field support services for the processing plant and recovery circuits at Quebec’s first diamond mine. Our scope of work covered process, concrete, structural, mechanical and EC&I engineering and detailed design for most of the process plant areas, including scrubbing, secondary crushing, screening, DMS, HPGR and the recovery plant. We also provided technical advice to the procurement partners, and technical support during fabrication and construction to ensure compliance with the design and for forthcoming commissioning. Commissioning is planned for the second half of 2016, with commercial production beginning in 2017.
