NICKEL PURIFICATION PLANT
A feasibility study was undertaken by Thakadu Battery Minerals (TBM) in 2017 to investigate the establishment of a 31,200 tpa Nickel Purification Plant (NPP) at the Lonmin BMR in South Africa to produce high-purity nickel sulphate for the global lithium-ion battery market. On the basis of the conclusions reached by the feasibility study, TBM and Lonmin signed an agreement to proceed with the detail design and construction of the Thakadu Nickel Purification Plant at Lonmin’s Marikana BMR plant. The complete EC&I component (Design, Management & Commissioning) was managed and executed by Erudite Projects on behalf of MET-63 & TBM.
COAL STOCKPILE FEED SYSTEM
Erudite Projects has been awarded the contract for the detail design and engineering of a 1.8 Mtpa strategic stockpile feed system.
The purpose of the feed system is to transfer coal from the power station coal beds to the new strategic stockpile. This will be accomplished by means of a Feed Conveyor that will receive coal directly from the coal bed stackers. The coal will then be transferred to a 1.4 km Reversible Overland Stockpile Conveyor that transports the coal to the strategic stockpile area. The Stockpile Conveyor then transfers the coal to a Rotary Kidney Stacker. From this point, the coal will be deposited by mobile machinery.
What makes this design exceptional is that the system will be designed to cater for the reclamation of coal in the future. This will be achieved by having an overland conveyor that can run in reverse. The coal from the stockpile will be transferred to the Reversible Stockpile Conveyor by means of a buffalo feeder which transports the coal back to the power station coal bed area. The tail end of the Stockpile Conveyor will be designed so that it transfers the coal back onto the Feed Conveyor which will feed the power station coal bed reclaim conveyors. The system was completed in Jan 2019.
SYLVANIA MOOINOOI FLOAT PLANT
SMD Sylvania Metals (PTY) Ltd (“Sylvania”) awarded G4eps the detail design of a new Flotation Plant at the Mooinooi Operation in Mooinooi.
The feed to the float plant are the rougher tailings of the existing plant, after fine grinding. The project must deliver the new float plant, regrind mill, utilities, reagents plant, concentrate storage tank, pumps, piping and valves, instrumentation and electrical infrastructure to accept all the rougher tailings from the existing plant at current operating densities.
TAILINGS RECOVERY PLANT
Erudite has been commissioned by South32 to conduct a concept investigation where a need has been identified to terminate the primary use of a tailings dam and to identify means of recovering the tailings material in a dry format and to replenish the plant service water with the water recovered during the process. The manganese fines recovered from the obsolete tailings dam and recovered material can be sold as a product, while the efficient recovery of service water will contribute to the environmental impact of that part of the plant.
TWO RIVERS PLATINUM MINE : PROCESSING PLANT UPGRADE
The LSTK contract was awarded to Erudite Projects during the first quarter of 2020 and is located in the Steelpoort area, Limpopo province. Currently the project is 92% complete with a planned commissioning start date of 15 November 2021.
The Works includes all detailed engineering, procurement and contract administration, fabrication and deliveries, construction and site supervision, including safety, health and environmental management during the execution of the Works.
The scope of this project is to increase the current plant throughput capacity with 15% by upgrading and incorporating the following:
- Utilising available spare capacity in the existing Primary Mill,
- Eliminating the current bottleneck by addition of a Secondary Mill which will operate in parallel with the existing Secondary Mill,
- Installation of additional Secondary Rougher float capacity,
- Upgrading the Secondary Mill Cyclone Cluster and Tailings Guard Cyclone Cluster,
- Upgrading the existing Primary Rougher Float capacity’
- Installation of additional Blower and Instrument Air Capacity.
The success of the project experienced to date is due to a continuous collaborative effort between Erudite, the Client and all the contractors and thanks goes out to the project team.
MOLO GRAPHITE MADAGASCAR
The Molo project is being undertaken by Erudite on behalf of Nextsource Materials (Canadian) and the project location is 13 km east of the village of Fotadrevo in the south of Madagascar. The resource will be extracted by means of open-pit mining, from where the ROM will be hauled to the ROM stockpile.
The plant is based on a modular design and procured from China where it will be erected and cold commissioned before being shipped to the site for re-erection and commissioning. The design capacity of the said plant will be 17 ktpa, and in order to achieve this, a ROM feed of 250 ktpa is required.
The process itself consists of primary and secondary crushing, primary and secondary milling, floatation, drying and ultimately the bagging of the concentrate. Logistics is a challenge as the product has to be hauled to a port about 160km away before being shipped to various clients.
MOLO PROJECT GALLERY
LOS CALATOS PERU
Erudite Strategies have been appointed by Executive Mining Group to complete a PEA level study to NI 43-101 standards of the Los Galatos Peru; Copper Molybdenum project. The project was previously owned by Metminco who completed various studies of the resource. The new owners who are UK based, aim to consolidate a number of alternatives in terms of infrastructure development, Mining and Process design through the PEA study.
Erudite Strategies completed a cyanide destruction study for IAMGOLD at their Essakane operations in Mali.
Erudite Strategies were tasked to Provide information for ENDEVA Pre-Study of the proposed 1MVA renewable energy solution for Zamsort’s copper/cobalt mine near Kalumbila, Northwestern Province, Zambia. Based on a various face-to-face, and Skype meetings held with ENDEVA, the need was expressed for a CAPEX for a PV solution to provide a more favourable take-off unit cost vs. that of the current diesel operating cost to Zamsort.
