94 E&MJ • DECEMBER 2018 SUPPLIERS REPORT Diamond processing technology specialist DebTech delivered an X-ray Transmission (XRT) sorter to South Africa's largest dia- mond mine to optimize its plant through- put by re-concentrating the product from the dense medium separation (DMS) stage. The XRT Coarse Concentrator unit was delivered to De Beers' Venetia mine in Limpopo province. Commissioning took place in November. The unit's modular- ized configuration, where all elements of the system are designed to fit into two 6-meter containers, makes for optimal assembly and testing under factory condi- tions, efficient transportation, and quicker commissioning on site, DebTech reported. The company's XRT technology has been specifically designed to provide an alter- native to a high yielding DMS plant. Partnership for Digitalization Underground Sandvik partnered with Newtrax Technol- ogies Inc. to digitalize Hindustan Zinc's SK mine. The former will deliver the Op - tiMine digital platform, which offers fea- tures for short interval control of the un- derground operations, including OptiMine Monitoring, Location Tracking and Mine Visualization, Scheduler, Task Manage- ment, and OptiMine Analytics. The sys- tem will be commissioned in 2019. Newtrax Technologies Inc. will de- liver personnel tracking solutions with cap lamps, tracking, and telemetry data for the entire mobile underground fleet, including non-Sandvik equipment, to include more than 150 drills, loaders, trucks and other equipment. The Newtrax offering will be integrated with the Sand- vik OptiMine digital platform, creating an integrated mine management solution, Sandvik reported. Hindustan Zinc is one of the world's largest integrated producers of zinc and among leading global lead and silver pro- ducers. SK mine is a highly mechanized world-class underground zinc and lead mine with an annual ore production ca- pacity of 5.5 million metric tons (mt). Separately, Sandvik reported it signed an agreement with Nokia to further devel- op Sandvik solutions for private LTE (Long Term Evolution) and 5G technology. The Nokia Digital Automation Cloud platform will initially be implemented and tested in the Sandvik test mine in Tampere, Fin- land. The platform can operate both under- ground and in open-pit mines, and offers connectivity for testing and developing Sandvik technology. It enables operation of autonomous vehicles, real-time monitoring of underground and outdoor premises to keep people and equipment safe, remote diagnostics and predictive maintenance, and asset management, control and au- thentication, Sandvik reported. FLSmidth to Deliver Kiln for REE Project The Rare Earths Hastings Technology Metals Yangibana Rare Earths Project, in Australia, contracted FLSmidth to supply an acid-bake rotary kiln. FLSmidth will design and supply the kiln and provide technical assistance. The Acid-Bake Ro- tary Kiln incorporates concentrate mixing and feeding equipment, directs waste gas to a separate scrubbing facility, and pro- vides a natural gas-fired heating system essential for the processing of rare earths. 2K Tons Limestone Per Hour Hauled Above Treetops Doppelmayr reported Cementos Progreso, S. A. selected RopeCon to haul limestone and marl 1.6 km from a crusher, over the treetops of the hilly San Juan Sacatepéquez countryside, and to the San Gabriel ce- ment plant in southeastern Guatemala. The limestone is mined in a quarry located roughly 200 meters (m) lower than the ce- ment plant. By using RopeCon to transport the limestone, the load crosses the terrain in a straight line despite the topography. The system requires no more than four towers over its entire length, Doppelmayr reported. The material is loaded on to RopeCon by a feeder conveyor and unload- ed at the unloading station via a housed-in De Beer's Plant Commissions X-ray Sorter De Beer's Venetia mine plant commissions a DebTech X-ray sorter in November.
