The commodities recession is severely impacting the mining sector, making it essential and even critical for companies to reduce costs and ensure production start-up as quickly as possible in order to generate cash flow.
FLSmidth’s Knelson gravity concentrators distributed across Africa by Gravity Concentrators Africa (GCA) are guaranteed to deliver on both fronts, particularly in the gold sector, writes Laura Cornish.
Gravity concentration weigh-up The recovery of easily-liberated free gold should be one of the primary drivers behind the start-up of any gold operation – especially in the current low commodity price economy.
“The advantages associated with gravity concentration are significant, financially and operationally. This is good news considering most gold mines in Africa have a free gold component within their ore bodies,” says GCA director Martin Meyer. Even mines with as little as 10% gravity recoverable gold will see the benefit. Fast gold recovery delivers cash flow, quickly. Once in operation, gravity concentrators also save costs as they don’t require reagents and chemicals for processing.
Consequently, they are environment friendly as well. The simple, uncomplicated machines also reduce downstream processing requirements. In some cases they enable a reduction in the size and residence time of the leach circuit as a portion of the gold has already been recovered upstream via gravity for example, Meyer outlines.

GCA distributes FLSmidth’s Knelson gravity concentrators on behalf of the minerals processing major and together the two companies have ensured the industry understands and recognises the benefits associated with the brand and the product. “We have significant market share across the globe which can be attributed to the product’s quality.
Some of our installations in South Africa exceed 15 years in operation, showcasing their robust and efficient capabilities,” Meyer reveals, adding that GCA are without doubt recognised as “gravity experts” in the mining sector. GCA also..
