AFROMIX recently supplied four large Cyanide Detox Agitators to a mine in Eastern Africa. These units are able to provide high mass transfer but still able to keep the solid suspended uniformly. Sufficient air is required with SO2 gas to destroy the cyanide complex.
Conventional gas dispersion systems offer good mass transfer but fail to keep the solids in suspension. The AFROMIX system makes use of a dual sparge system which can operate with air or oxygen. The sparges have been fitted with AFROMIX's non-return valve system which prevents the sparges from blocking even at high percentage solids.
SX MIXERS – DRC
Solvent Extraction mixer were recently supplied to a copper mine in the DRC by Afromix. The units were fitted with AFROMIX's R6 pumper impeller offering high flow with very low shear for Solvent Extraction applications.
The mixers are required to advance flow and disperse the fluids. These mixers were designed to reduce entrainment loses and induction of air which can be detrimental to the process.
URANIUM PLANT IN NAMIBIA
A major, new uranium plant in Namibia was experiencing constant mechanical failures on their recently installed agitators. Problems included shaft breakages, gearbox failure, and other associated problems.
After a visit to the site AFROMIX submitted a report, together with recommendations, to resolve the problems. Initial components were provided within three weeks, and complete rectifications within three months.
No reported mechanical failures have occurred since installation.
WEST AFRICAN GOLD MINE
AFROMIX was requested to provide replacement agitators for a plant that was experiencing severe process and mechanical problems.
Following a site visit to assess the problems, an order was given for the replacement of all 12 CIL agitators. Because of the severity of the problems highlighted, a delivery of six months was requested – three months shorter than the quoted delivery. All 12 agitators were delivered on time, with AFROMIX assisting in the transport of all components to site by air – a total consignment weight of 100 tons. Following installation, the plant reported improved extraction of between 88% - 92%. The units supplied were the largest Gold Leach agitators in Africa.
AFX PUMPS AND AMX AGITATORS TRAINING
On the 9th and the 10th of November 2016 AFROMIX hosted their first in-house training and it was presented by Toby Frostwich and Eugene Els. The training was based on the company’s product and service offerings.
ELECTRA MINING 2016
AFROMIX took part in Electra Mining 2016. Electra Mining is the biggest mining exhibition in Southern Africa. AFROMIX exhibited their AFX150 peristaltic pump and latest agitator technology at the exhibition.
