HIGH PROFILE systems and its world leading comminution database as well as its worldwide project knowledge base in comminution. Elsewhere in the global market Latin America is a real stronghold. More than 35 major pieces of capital equipment have been shipped to Vale in Brazil over the years, and a spare parts centre serves Vale specifically. The CITIC HIC presence in Brazil includes a direct subsidiary, CITIC HIC Brazil in Nova Lima near Belo Horizonte. In Chile, Codelco is a major customer, as is BHP (equipment bought includes a 4.5 m by 8.4 m scrubber in 2008), served by direct subsidiary CITIC HIC SpA in Santiago. There is also a brand new service centre under development in Chile. In Peru there is also a direct subsidiary in Lima and spare parts centre serving the CITIC equipment operating at Shougang Hierro Peru’s iron ore operations. Most recently in May 2019 a ball mill shell was shipped from CITIC Censa to the Las Bambas copper mine in Peru. In South Africa, CITIC HIC has its office in Johannesburg. In South Africa and in central and southern Africa generally, China’s Belt and Road initiative has seen a number of Chinese financial institutions establish themselves in that part of the world, which has helped CITIC HIC increase its presence in Africa. In India, a direct subsidiary is located in Mumbai. In the 2000s the company supplied a 7 m x 4.1 m SAG mill and a 5.03 m x 8 m ball mill for Hindustan Zinc’s Rampura Agucha project. Finally there are also subsidiary offices in Silverwater (NSW) in Australia, Pointe Claire in Quebec, Canada and a range of dealers and representative offices in many other locations such as V-Line in Saudi Arabia. All of the big global miners have sent delegations to Luoyang to CITIC HIC over the years, which has been crucial in its success with these customers. Jin Song says: “It has been very important for us to show the real CITIC to customers. We always invite major potential customers to visit us – often they have had misconceptions about us as a Chinese company thinking we use old technology and an old management style. But that soon changes when they get to know us. Coming here they can see for themselves the quality of our machining equipment, our in-house R&D and unique technologies and our list of mining references. The world’s mining majors no longer think Chinese products have a lower standard, and this has been proven again and again. And we have already been following the major international standards for many years including ISO9001 and ISO14001. We are a certified supplier to Rio Tinto, BHP, Anglo American and others, not something 70 International Mining | MARCH 2020 IM Editorial Director with some installation models at CITIC HIC in Luoyang, a huge site and one which is uniquely vertically integrated that is easy to achieve. We also provide the service element of the business and our target is to provide a complete lifecycle solution to clients from the equipment order through to life of mine operation of the equipment.” Other major mill deliveries include to the Erdenet copper mine in Mongolia; Western Areas Cosmos Nickel Complex in Australia, to the Chambishi and Konkola copper mines in Zambia, ArcelorMittal iron ore mines in Liberia, Marampa iron ore mine in Sierra Leone, Managem’s goldmine in Sudan, cobalt mines in DRC, the KSO gold mine in Laos, the Mirador copper project in Ecuador, Ma-aden’s phosphate operations in Saudi Arabia, Runruno Gold in the Philippines – the list is extensive. On the crushing side it has delivered the gyratory for a semi-mobile crushing station at LKAB’s iron ore operations in Sweden. For all these global projects it doesn’t end with commissioning, CITIC HIC sends teams to stay onsite to guarantee the stable operation of the projects. This is not even mentioning its dominant market share in China itself where major mill customers include all the largest mining operations such as Zijin Mining, China National Gold Group, Jiangxi Copper, Western Mining Group, Hanking Group, Chinalco, Tongling Non Ferrous, TISCO, Baosteel and many others. Manufacturing The site in Luoyang includes everything required for large mineral process equipment manufacture even to the point of having its own plant making oxygen and other gases onsite. All castings are done in-house. Casting equipment includes 80 t, 50 t & 30 t electric arc furnaces, two 150 t & 60 t LF ladle refining furnaces plus 150 t & 60 t VD/VOD refining furnaces for liquid steel. CITIC HIC can pour 900 t of liquid steel at one time with its largest casting to date being 600 t. It produces around 70,000 t of high quality liquid steel per annum. In forging, IM saw the jewel in the crown on the tour, a hydraulic press of 18,500 t, the world’s largest. It has its own oil and water treatment facilities for quenching, carburising and nitriding. It can produce everything from small forging rings up to the world’s largest mill gears. The list of unique and special machines for equipment manufacture is extensive including a special unit for hole drilling in trunnion heads; three 10 m diameter DVT1000 CNC double column vertical lathes in each of its three main factory buildings. It also has four 16 m diameter DMVT1600 units. Then there are numerous vertical and helical gear teeth machining units from Germany & China. It has a MAAG 12 m diameter gear cutter and Waldrich Coburg machining rig. All welding of shells is done in house. In all CITIC HIC owns over 3,000 machines, including more than 70 CNC machines, some of which are the largest and most advanced in China and the world. There are approximately 30 large CNC movable planner boring & milling machines and floor-mounted boring & milling machines. The only major component supply exception is that some motors and gearless drives are sourced from ABB/Siemens though this is in common with all the other players. Some large bearings are also sourced from specialists like Schaeffler and SKF, again common with the main competitors. Where Western players get orders for projects in China or use Chinese factories for assembly are mainly buying castings from CITIC HIC. Metso, FLSmidth and others used to buy a lot of mill shells and other castings from CITIC HIC in China but this is no longer the case. Testing is extensive. Large mills are fully assembled with gearbox, pinion and motors for tests which make sure oil pressure, electrics, rotation speed, vibration etc are all within set parameters. Simulation is also carried out to see if the PLC system is working well enabling the mill to start and stop quickly if needed. The QA department meets ASTM and Chinese and EN standards, all met with its own equipment not external labs. It uses sampling and calibration technology such as NDT, ICP and XRF. Mine winders are shipped in two halves. Large SAG and AG mills see the head shipped separately from trunnions but for ball mills they are shipped combined. Similarly ball mill shell are shipped bolted together but SAG/AG mills are shipped as two halves with the main bearing pedestals shipped on their own. Stirred mills and HPGRs For fine grinding, CITIC has had considerable success with supplying stirred mills, including a CSM-1200 Vertical Stirred Mill supplied to Codelco
