The new Multotec SX10 spiral features super-concentrate darts for leaner coal with less waste in a single stage.

Multotec manufactures a range of slurry feed distributors, launder systems and spiral accessories. spiral can provide significant savings in terms of overall production efficiency,” Erasmus adds. “Testing usingMultotec’s NHM12 spiral is going very well at sands plants in Australia, where banks of our new spiral technology are be- ing used alongside magnetic and electrostatic separators for better product yields,” he says. Multotecspiralsaremanufacturedinthecompany’sSpartanfactory in Gauteng, South Africa, along with all feed distributors and product boxes. “We have gone through the SABS local content verification process and, with verified local content greater than 60%, we exceed the requirements of the newMining Charter. Our products are exported all over the world and used on all six continents across a full spectrum of minerals. Our process engineers understand process flow sheets better than anyone in the market, so our purpose-built spiral concentrators can quickly and seamlessly be integrated into mineral processing circuits,” Erasmus concludes. q

Thermal coal and coking coal can be produced on one spiral with the Multotec SX10 spiral. recovery process, beneficiating the discards. In today’s constrained mining environment, newmarkets forminerals recovery are becoming of more and more interest. Mineral sands solutions Multotec has an increasing range of products designed to suit heavy minerals such as ilmenite, rutile and zircon. “For these mineral sands we developed a 12-turn spiral, the NHM12, which offers significantly longer retention times. In principle, using two six turns in serieswould have a similar effect, but the reduction in distributors and auxiliaries makes 12-turns a more cost effective solution,” he tells MechChem Africa . “While it’s tricky to put a 4.5 m spiral into a plant, a bigger
