THE CHALLENGE

Bellzone has two extensive iron ore assets in Guinea,: Forecariah and Kalia. In 2012, a 15-year mining licence was granted to the company for the vast 319km² Forecariah site. And the company turned to CDE to help increase efficiencies in its production process. The existing crushing and screening equipment on site was producing fines with a lower iron content affecting the quality and commercial value of its product.

THE SOLUTION

A fast track installation, capable of producing a high quality product was required and CDE’s M2500 mobile processing and AquaCycleTM thickener was identified as the right solution.

CDE tailored M2500 iron ore wet processing system was developed to effectively remove the ultra-fine fraction to ensure that the remainder of the crushing and screening plant fines contained a high enough iron grade to be sold directly to market.

CDE quickly identified the need for low grade fines to be efficiently separated at 1mm to produce a +1mm product which can go direct to port for sale, with the finer fraction passing to the CDE EvoWashTM to remove the Gangue, therefore upgrading the entire fraction to a saleable product.

An AquaCycle thickener water recirculation system was also incorporated to effectively recover the process water, again enhancing efficiency and maintaining a compact footprint throughout the entire process.

"CDE was the chosen provider on this project because of its high level of expertise in wet processing technology and its ability to develop and produce high quality, integrated modular solutions. One of the most imperative factors for us was to source a provider that could develop a modular system which is suitable to transport easily, erect quickly on site and operate in a remote location".
Rod Davies, Process Manager, Bellzone

THE RESULTS

With a 250 tonne per hour feed rate of low grade fines the washed product from the CDE plant will be directly exported for the Forecariah Guinea Mining SA operation. The effective removal of contaminants produced a consistently  +58% Fe level from the low grade fines stock. A highly efficient process producing minimal waste delivering a high product yield.
