MINEXXT provides expertise with equipment and process auditing, pilot test campaigns and other site or field activities that result in an improvement in process performance.

We utilize our global experts and proven technologies such as dynamic test work, CFD modelling and process designs, to provide the most practical and efficient solutions available.

Providing equipment optimization by way of upgrades, retrofits and overall modernization has proven to reduce operating and maintenance costs, extend the life and reliability of the equipment and increase performance. Payback is almost immediate, and the up-front investment is minimal compared to equipment replacement.

Our Services

 

Equipment & Process Audits

Equipment & Process Audits

Our specialists have conducted more than 200 thickener audits to date, and we have found these to be the foundation for identifying bottlenecks and inefficiencies in the process.

Equipment Upgrades

Equipment Upgrades

An upgrade of select components on the existing equipment may be all that is required. This improves performance and often extends the life span of the operation.

Installation Commissioning  Support

Installation & Commissioning Support

Having the experienced support available can reduce the installation period, mitigate risks and ensure a seamless transition between installation, commissioning and start-up.

test work and pilot plants

Site Test Work & Pilot Plants

Laboratory based tests are often performed to determine the basic parameters and confirm the type of technology to be used. Pilot scale test work on the other hand is usually carried out as a secondary measure for confirming the type, size and configuration of minerals processing equipment. These results provide a better indication of what to expect on a full-scale commercial unit.

Pilot-scale test work includes:

  • Material and slurry characterization
  • Dynamic thickening - paste, tailings and concentrate for all applications
  • Sampling and slurry analysis
  • Flocculant screening - optimal type, make and dosages
  • Rheology - measuring and recommendations
  • Beach slope prediction - pilot scaled flume tests
  • Pilot plants - designs, construction, supply and operation

Specialised Equipment Development

 

Product design and development is one of our specialties. Development is carried out from the conceptual design stage to validation using  CFD modelling, physical models, sophisticated simulation software and bench-scale test work. Once validation has been completed, we then take the product through to final design, construction, supply, installation, commissioning, and start-up.

Site and application specific products and novel process solutions can maximise performance and increase process efficiencies. These products are often unique, being tailored or custom built to a specific plant or process requirement; they are well suited for problematic applications where standard equipment or outdated technologies are currently being used.
