Australian mineral-recovery equipment developer, Gekko Systems, in conjunction with Randgold Resources, is pleased to announce that a Gekko continuous inline leach reactor (ILR) used at the Morila Gold Mine, Republic of Mali, West Africa, is to be converted into a batch ILR. The modernization represents a collaborative effort between Gekko Systems and Morila.
A Gekko Systems’ ILR 1000CA has been in use at Morila since May 2001 providing recovery rates, depending on feed, of 200oz to 2,000oz/day. Capable of treating 1t/h of concentrate, the continuous ILR is regarded as an essential component in gravity gold recovery at Morila.
The ILR 1000CA will be converted and modernized to a current configuration batch ILR2000BA. Since their 2002 introduction at Target Mine, South Africa, and Kelian Equatorial Gold, Indonesia, batch ILRs have demonstrated outstanding operability and recovery. Routinely treating 12t/day of concentrate, they have become the processing unit of choice for many mineral processing companies.
“Gekko Systems’ association with Randgold Resources and the Morila Mine dates back to May 2001,” said Ms Elizabeth Lewis-Gray, CEO of Gekko Systems. “The conversion of the original ILR to a batch ILR extends our collaboration still further and affirms the operational commitment of both companies to economy, efficiency and innovation. We look forward to the modernization of the existing ILR, and wish Randgold Resources and Morila well in their gold recovery operations.”
In order to minimize downtime, contain costs, and maximize on-site benefits, the existing ILR will be converted using equipment, modifications and programming specifically developed by Gekko, and by sourcing on-site spares at Morila.
Gekko ILR experts will perform the conversion while Morila personnel will make all necessary piping adjustments. Gekko engineers will reprogram the existing control system for batch duty.
Mr Drissa Arama, plant manager at Morila, said: “The Morila Gold Mine is currently entering a new phase of operation with the aim of ensuring that the resource balance of the mine’s life is fully exploited. At Morila we have observed the excellent operability and performance of batch ILRs elsewhere in West Africa. It is our judgement that the Gekko batch ILR will offer us improved efficiency and operating economies. We look forward to the installation, to the success of the Morila Gold Mine, and to our ongoing friendship with Gekko Systems.”
