ConsultaThe coldest winter month is January with the average outdoor temperature -20°С. The warmest summer month is July with an average outdoor temperature of +19.8°С. The air temperature usually reaches +25 to +27°С in the middle of the day; sometimes it rises to +40°С. A frost-free period usually lasts for 4.1 months.
ConsultaKaunis Iron’s open-pit mine in Pajala is just the starting point of the ore’s journey to customers around the world. Here you can read about the process to refine the much-wanted iron ore. Drilling and blasting. In the open pit, holes are drilled first of all and filled with blasting agent. Usually, 150 – 300 holes are drilled, which are
ConsultaSeveral methods / techniques such as washing, jigging, magnetic separation, gravity separation, and flotation etc. are used to improve the Fe content of the iron ore and to reduce its gangue content. These
ConsultaAbstract The origin of the soft ore at the S11D iron mine in Carajás was investigated using 20 samples from a diamond drill hole. The methods of analyses were X-ray diffraction (XRD), optical microscopy, whole-rock chemistry, and scanning electron microscope

ConsultaA major project called Carajás Serra Sul S11D Iron project for the expansion of mining and processing at the Carajás Mining Complex is under construction. It involves a total investment of $19.67bn, including $8.08bn for installing the new mine and processing plant, and $11.59bn for the logistics infrastructure.
ConsultaS11D's iron ore processing plant will use a system developed by Vale that will cut water consumption by 93%-enough to supply a city of 400,000 inhabitants. Already employed
ConsultaS11D: largest iron ore project in Vale's history. t, which will start up in the second half of 2016Located in the municipality of Canaã dos Carajás, in southeast Pará, S11D is the largest iron ore project in Vale's history, with an estimated produ. tion capacity of 90 million metric tons per year. Sixty per cent of the physical construction
ConsultaFroth Flotation is one of the fundamental processes used in iron ore attainment. It involves various physical–chemical reactions, and its multivariate control is not trivial.
ConsultaActivities involved in finding, mining and processing iron ore at our Pilbara operations have been simplified in the following diagram. Rio Tinto operates 11 iron ore mines in the Pilbara and the specific sequence of activities varies from mine to mine. Excellence in planning, scheduling and quality control are fundamental to the process.
ConsultaThis patented process produces a high strength nitric acid – typically around 55-60% HNO 3. Over 99% of the initial acid used in the leaching process is recycled. The 5% makeup acid is typically 30-80kg of acid
