Extraction of Iron from its ores. The ore dressing. The aim of ore dressing is increasing the concentration of iron in the ore by removing the unwanted impurities,3.2.7 Extraction of Metals - Environmental aspects of,,This has to be done on a large scale to make it economically viable. The benefits of recycling are that: 1 Waste material does not accumulate in the environment and cause visual and actual chemical pollution; 2 If the scale is right recycling can cut the cost of production by providing a cheaper ore; 3 Less mining need to be done. This leads to less disruption and pollution of the environment,Iron ore extraction techniques - ScienceDirect,01/01/2015· This chapter seeks to examine the systems of work that were used underground in two UK iron ore mining regions to present an historical perspective. Later sections will go on to contrast these mining operations with the modern deep mining techniques applied in Sweden and the huge scale surface extraction of iron ore in Western Australia and Brazil.3.2.7 The extraction of metals,(b)€€€€ Iron produced in a blast furnace is impure. The iron contains carbon, sulphur and phosphorus. State how each of these impurities is removed. Explain why sulphur is removed before carbon and phosphorus. (6) (c)€€€€ Although there are large reserves of iron and aluminium ores in the world, both metals are recycled.
