He notes that African alluvial gold and Diamond mines that aim to increase productivity tend to be inclined towards using the CDE AggMax™ logwasher, in combination with the bespoke R-Series primary scalping screens, as this results in “a continuous plant operation in some of the stickier feeds – regardless of the rainy season”.
Advances in Diamond Processing
Meanwhile, Du Plooy points to significant advances in diamond recovery, were using the latest technologies have become the norm. “This has shown the need for cleaner, uncontaminated feeds to the diamond selection process with continuous operation and reduced loss potential.” This need for a cleaner feed material to process in diamond mining has been addressed advanced materials scrubbing systems like the AggMax™.
Moreover, the ability to recover larger-stone sizes using CDE’s technology has further increased demand for the AggMax™, as it cleans and scrubs without causing damage to the stones, also removing contaminants from the feed material and increasing the potential of discovering stones before passing to the crushers. This can help create additional revenue streams with a higher quality aggregate material produced as part of the washing process.
New Possibilities for Mining in Africa
Mining in West Africa is opening up new growth possibilities, Du Plooy notes, adding that the shift from companies in the region, from just barely providing an adequate amount of capital expenditure to 'proper investment' in the latest technology, has driven demand for state-of-the-art solutions.
He adds that CDE is progressing opportunities with various stakeholders and mining investors who are seeking to implement CDE technology at mines in West Africa and Southern Africa, ranging from diamonds to rubies and emeralds.
Du Plooy notes that CDE hopes to replicate its successes in the Australian market by offering our proven modular technologies to African countries for the enrichment of low-grade iron-ore stockpiles, as these countries are expressing greater interest in the abovementioned technologies amid the depressed iron-ore environment.
