Iron Ore Mining Techniques Metal Extraction
Iron ore mining can be broadly divided into two categories namely 1) manual mining which is employed in small mines and 2) mechanized mining is suitable for large iron ore mines Manual mining method is normally limited to float ores and small mines Mining of reef ore is also being done manually on a small scale Iron ore mining industry has played an important role in China’s economic growth From 1996 to 2010, the average annual growth of GDP and iron ore production, respectively, was 987 and 601 per cent During the same period, the imports of iron ore grew on average by 2064 per centRD activities and FDI in China’s iron ore mining industry Depending on the enduse of the iron ore(pig iron, sponge iron, commodities such as cement, etc), different mineral properties are required Table 5 Iron ore sizes (CVRD 1985, QUARESMA 1987) Iron ore is subjected to several processing stages to increase the iron content and reduce the amount of mineral impurities, depending on its end useNATURAL RESOURCES SUSTAINABILITY: IRON ORE MININGAt present, iron ore resources are decreasing day by day, which is characterized by more lean ore than rich ore, more associated ore and complex ore composition Xinhai Mining, as a mineral processing equipment manufacturer with over20year experience, provides responsible iron ore processing technologies by different type of iron oresExtraction of Iron, Iron Mining, Iron Ore Processing With the increasing demand for iron ore, the number of open pit iron ore mines and mining rate are increasing, and there are more and more problems faced in the process of iron ore mining, which seriously affect the safe production of mines This article takes a look at the problems and improvement measures in the open pit iron ore mining processProblems and Solutions in Open Pit Iron Ore Mining
