The Isua iron ore project is located in Greenland, approximately 150km north-east of Nuuk. The project is owned by London Mining and includes the development of an open pit mine, ore processing plant, shipping and other necessary facilities and infrastructures.
Iron ore must go through a lengthy pre-processing stage before it can be pelletized a series of steps that work to beneficiate and concentrate low-grade ores. This process varies depending on the ore source, but typically involves various stages of crushing and grinding to reduce the size of the iron ore.
