Current Projects

Kinsevere Expansion Project (KEP)

MMG (Minerals and Metals Group) appointed METC Engineering in Nov 2019 to complete a Feasibility Study for a 2.2 Mtpa sulphide copper and 2.2 Mtpa oxide copper concentrator at Kinsevere Mine.  The project is located in the Katanga Province in the DRC, located approximately 35 kilometres north of Lubumbashi.  The process recovers sulphide copper (crushing, milling, flotation, roast, leach, solvent extraction and electrowinning) and oxide copper (crushing, milling, flotation, leach, solvent extraction and electrowinning) to produce 80 ktpa copper cathode.  The current Feasibility Study focuses on the sulphide circuit and the oxide flotation which is additions to the current Kinsevere Mine flow sheet which only treat oxide ore through a crushing, milling, leach, solvent extraction and electrowinning flow sheet.  Also part of the Feasibility Study is the addition of a hydrometallurgical Cobalt Plant to recover 4000 tpa cobalt to the current Kinsevere Mine processing plant as well as a new tailings storage facility (TSF3) for the basic copper tailings from the sulphide copper flotation circuit.  METC Engineering’s scope for the Feasibility Study include engineering design, implementation planning and procurement of long lead items in preparation of the implementation phase due to commence in H2 2020.

 

Sierra Diamonds (Newfield)

Sierra Diamonds Limited appointed METC Engineering to detail engineer and design, project manage and procure a 100t/h Diamond Processing Plant Project. The project is located in the eastern province of Sierra Leone of West Africa in Tonga approximately 314 km from Freetown. The process plant recovers diamonds in a 25mm and below size range using the well-known Dense media separation and XRT sorting technologies. A feed run of mine kimberlite ore will be crushed in a three stage crushing circuit and washed through a scrubbing unit prior the separation and recovery of diamonds. An added Tomra sorting technology is included in the plant for further sorting of kimberlite ore prior tailings disposal. Slimes collected around the plant will be dewatered and pumped to the slimes dam with water recovered from the dam pumped back to the plant. Diamonds recovered through the mentioned technologies will further be sorted in a final recovery building which comprises of the Debtech sorters and glove boxes then stored for dispatch and sales.

 

METC will also assist Sierra Diamonds with the procurement of all mining operations equipment and the upgrade of the existing operational infrastructure.

 

Mutoshi Phase 1 Cu & Co (Chemaf/Shalina)

METC together with Outotec are providing the Client with an engineering design for both basic and detailed engineering, procurement, logistics and construction support for a green-fields Copper (Cu) and Cobalt (Co) recovery plant in Kolwezi, Democratic Republic of Congo (DRC). The Client will be mining a large open pit to provide oxide ore for processing through a crushing, acid milling, acid leach, CCD, SX-EW and cobalt precipitation plant. The design also includes a sulphur burning acid plant and a separate sulphur burner sulphur dioxide gas plant. This project is in construction.

 

 

Prieska Zinc & Copper Project

(Orion Minerals)

METC have provided an experienced metallurgist for the clients owners team. The client has also relied on the METC team to provide engineering review and design input on some aspects of the project and the METC chief metallurgist signed off as the competent person for the release of the scoping study to the ASX. The project is located in the Northern Cape Province of South Africa and is evaluating re-starting the historic underground Prieska Copper Mine.

Kipushi Zinc Project (KICO SA & Ivanhoe)

METC have been appointed to complete the detailed engineering and procurement for the Kipushi mine in the Katanga province of the DRC (30km from the main centre of Lubumbashi). The design is to produce a zinc concentrate receiving ore from the underground mine, crushing rejecting waste with a DMS plant and then processing through a concentrator plant to produce a high grade zinc concentrate. The Kipushi mine has been in care and maintenance for a number of years and this project will restart this historic mine and reinvigorate the town of Kipushi.

Bilboes Gold

Bilboes Holdings (Private) Limited appointed METC Engineering in Oct 2019 to complete an owners team review of a gold processing plant feasibility study design and supporting  infrastructure for the Bilboes project.  The Bilboes project consists of the Isabella-McCays complex situated 75 kilometres north of the city of Bulawayo in the Matebeleland province of Zimbabwe.  The 240 ktpm process plant recover gold  through a flow sheet consisting of two-stage crushing, milling, flotation, biological oxidation (BIOX) and leaching, carbon in leach (CIL), electrowinning and smelting.  METC Engineering proposed some value engineering initiatives to reduce the capital costs and improve the economic viability of the project.

Voyager PGM and Cr (Tharisa Minerals)

Tharisa Minerals, situated in Marikana, NW province, South Africa, is the largest single chromite processing plant in the world with a PGM processing concentrator on the tail end of the facility. Additional PGM flotation capacity was required and METC successfully installed high energy rougher and cleaner flotation cells within the existing flotation banks. The value-add to the Client was the fact that the installation of the flotation cells were completed whilst the plant was operating. Integration and execution of civils, E&I, discharge tailings and piping was designed in such a manner that the tie-in of the new equipment was completed during a planned shutdown period. No loss of production was experienced during the construction phase.
