Explain How We Extract Iron Ore From The Ground

why minerals are mined and processed to extract metals,metallurgy and mineral processing372 . depending on the mineral and metal, the process stages can include mineral processing that upgrades or concentrates the mined ore, andrather than looking primarily at the economic issues of how to extract metals and minerals from ore, they investigate why and how things behave the way....tin ore extraction mineral processing metallurgy,may 24, 2016 the flowsheet below explains the extraction of tin ore as shown by a study adapted to the concentration of a lode tin deposit.cassiterite (sno2) is very friable and special considerations to crushing and grinding of the ore are necessary to avoid an excessive production of fines. the mineral jig is an important feature of this flowsheet to recover the coarse free tin mineral as soon as liberated..

GCSE Metals Revise how Unreactive ones are Extracted

GCSE Metals Revise How Unreactive Ones Are Extracted

the non-metal carbon is more reactive than metals like iron (which we use to make steels) and copper (which we use for things like water pipes and electrical cables). this means that it is relatively cheap and easy to obtain these metals. simply heating the unreactive metal oxide with carbon will reduce the metal, displacing it from the ore.
