Kenmare Resources plc appointed Aveng Engineering to detail design, construct and commission the expansion of the Moma Titanium Minerals Mine on the north-eastern coast of Mozambique.
The Minerals Separation Plant (MSP) of the Moma Titanium Minerals Mine processes the titanium minerals ilmenite and rutile, as well as the zirconium silicate mineral, zircon. A heavy mineral concentrate (HMC), consisting of all three minerals, is produced by the floating plant. This is then pumped to the MSP, where it is separated into the final products for export via Kenmare’s company-owned port facility.
Aveng Engineering appointed Greene Consulting Engineers (Pty) Ltd for the civil- and structural engineering design, as well as construction monitoring services of the MSP. Being on the coast, the location of the site is a highly corrosive environment, and also falls in a cyclone region for which the appropriate design wind loads had to be researched in collaboration with the CSIR.
The structural design of the tailings stacker according to the client’s specifications. The stacker is designed to be moved/towed around to new stockpiling positions by bulldozers
The civil- and structural design of a new steel building to house the Wet High Intensity Magnetic Separation (WHIMS) circuit at the front of the ilmenite circuit of the (MSP). This building also houses a 10-tonne overhead crane
Reinforced concrete pump house to deliver water from the new raw-water dam to the various areas as required
The product storage facilities for the final products were increased from 140 000 tonnes storage capacity to 220 000 tonnes storage capacity
Magnetics and non-magnetics material skid stackers to stockpile these products around the MSP area. These stackers were also designed to be moved/towed around to the required stockpiling areas
Kellogg Company had nine production facilities in their Asia Pacific region in 2010. At that stage, the newly appointed Director of Engineering for the region required a comprehensive assessment to be conducted at each facility in order to establish the condition of the infrastructure and how it impacted their food safety in the long- and short term. The information collected was classed into four main categories: emergency repairs; repairs; preventative maintenance; and upgrades.
Based on the assessment reports, informed decisions could be made regarding budget allocations, future projects, expansion requirements and emergency work, to ensure the infrastructure remains fit for purpose for the foreseeable future.
Kellogg’s appointed Greene Consulting Engineers (Pty) Ltd to visit each factory and asses the infrastructure, its condition and the impact its condition has on the functionality of the facility. A comprehensive report was to be compiled, describing each area of the infrastructure, its status and required improvements. The proposed alterations to the facility were also discussed in the report. Costing for the proposed repairs, upgrades and expansions was an important deliverable of the project.
Howden Africa engineer and construct, among others, systems for mine ventilation. Their product line includes some of the largest surface mine ventilation fans in operation, as well as smaller fans for auxiliary and booster applications.
Greene Consulting Engineers (Pty) Ltd was approached by Howden to design the foundations of the surface mine ventilation fans. This would allow them to offer a turnkey solution to their clients. The fact that Howden’s product offerings can be customised and are constructed in all types of difficult mining environments drives Greene to design creatively. Dynamic analysis of the foundation structures is of the utmost importance. The varying ground conditions and equipment operating frequencies influence the natural frequencies of the structures and, therefore, the variations in designs.
Greene was requested to design the foundations, motor houses and service platforms for surface mine ventilation fans installed at:
The Expanded Public Works Programme (EPWP), launched in 2004, is one of the South African government’s short-to-medium term programmes aimed at reducing unemployment. The EPWP has achieved this aim through the provision of work opportunities, coupled with training.
The EPWP is divided into four sectors, creating work opportunities in each sector:
The EPWP also provides training-and-enterprise development support at a sub-programme level.
The project scope of services consists of the following:
