Leading mineral process company, Multotec Process Equipment, will be providing continuous ion exchange (Clean-iX®) metals processing scavenging equipment to a customer in the DRC. The equipment, using Clean-iX® ion exchange technology from Melbourne- based metals recovery and industrial water treatment specialists Clean TeQ, will treat up to 20 million litres a day of a raffinate stream, removing contaminant metals and improving the quality and environmental rank of the raffinate before it is processed further. Ion exchange technology for DRC project The technology is built on the founda- tions of batch ion exchange, a process that has been used in the industry for over 50 years. The Clean-iX® process allows the extraction of metals from clarified leach liquors using a ‘moving packed bed’ col- umn, maximising adsorption; this method of extraction has higher efficiency than conventional technologies. As a leading provider of high-quality mineral processing equipment and solu- tions to the mining, mineral processing, petrochemical and power generation industries, Multotec has an exclusive tech- nology distribution agreement with Clean TeQ for the African continent.

the knee rail is drilled and then flared on both sides. The top is also flared and a half round cap is welded into place. The base plate is 8 mm thick and welded to the tube. The clean modern lines are attractive and the stanchions offer a variety of stan- dard angles and matching accessories. Bends and closures common to mild steel systems are also available for this stainless steel system. Hand-, knee-rail and bends are manu- factured from 31,8 mm diameter tube with a 1,5 mmwall thickness. Bends and closures have swaged ends, improving speed of installation and preventing moisture from The DRC project is the second contract awarded in the past 12 months in which Multotec has applied Clean TeQ’s technol- ogy offering. Multotec is also currently implementing a continuous ionic filtration wastewater treatment solution at a mineral processing plant in the Middle East. Multotec Group, tel (+27 11) 923-6000 “The DRC contract confirms the rapidly increasing global interest in the application of continuous ion exchange technology for metallurgical scavenging and water purification,” she says. “The installation is expected to offer another valuable refer- ence for the efficacy and cost effectiveness of the process, for which there is a large potential market.” In metals recovery and purification, Multotec is able to draw on Clean TeQ’s Clean-iX® technology. There is also a suite of water purification technology from Clean TeQ that includes Continuous Ionic Filtration (CIF®), DeSALx® for desalination and sulphate reduction, and HiROx® for high recovery reverse osmosis.

Carien Spagnuolo, Senior Process Engineer at Multotec Process Equipment, says the group leverages its extensive sales and service network in African countries to bring customers leading edge technologies from around the world, especially for niche applications or difficult to treat waters.

Consistent demand for stainless steel handrailing Stainless steel tubular handrailing still out- ranks its competitors for many applications and Andrew Mentis confirms that demand for this product remains consistent.

corrosion and damp can cause accidents as well as raise maintenance costs,” he notes. “Mentis’ stainless steel handrailings improve safety and reduce maintenance, and by doing so create a more productive work environment. And more importantly, impact positively on profitability.” Quinlan says Andrew Mentis produces stainless steel handrailing in three alterna- tive grades: 3CR12, 304 and 316 stainless steel. Stanchions are 45 mm in diameter with a 2-mmwall thickness and base plates designed to allow moisture to drain from the stanchion itself, adding to the corro- sion-resistant benefits.

Corrosion resistant and maintenance free, stainless steel handrailing is the first choice in numerous applications including corrosive and damp environments. “This is because it’s aesthetically pleasing and offers scratch and stain resistant proper- ties making it the obvious alternative to traditional mild steel or painted handrail- ings,”Lance Quinlan, Marketing Manager at Andrew Mentis, says. “Weakened handrailings caused by
