Advantages of stage involved of extraction of iron ore after mining

environmental strategies in the mining industry onethe extraction of ore from underground or surface mines is but one stage in a complicated and timeconsuming process of producing minerals. a mine is born through exploration and mine development. this is followed by mining and beneficiation, and ends with mine closure and rehabilitation.small scale mining an overview sciencedirect topicsaug , · small scale mining. asm refers to the lowtech, labour intensive mineral extraction and processing found across the developing world (hilson and mcquilken, ), encompassing varying degrees of formality and legality, characterised by low levels of environmental, health and safety awareness (hilson, 02 4), and usually located in remote rural areas (hilson, 02). sme mining engineering handbook, third editionto put only the demand for iron ore in perspective, the world needs five more rio tinto pilbara mine operations producing nearly 0 mt iron ore annually [2]. in addition, the copper demand fromgrasberg open pit copper mine mining technologyextraction of ore from the grasberg block cave underground mine commenced in the second quarter of , which is the same ore body mined from the surface in the grasberg open pit. the mining of the final phase of the grasberg open pit was completed in q4 and the mine transitioned from openpit mining to largescale underground mining.
