this method is used to concentrate ore having the lower melting point than the impurities. for example, stibnite, an ore of antimony which has low melting point, can be concentrated by this method. the powdered ore is heated on the slopping floor of a furnace and the temperature is adjusted to be just above the melting point of the ore.
compared to other metals, iron is cheaper and also more durable. it can withstand the environmental wear and tear for long.even minute fences which can prevent insect entry into homes and building like mosquito mesh are also made of iron (steel)furnaces: furnaces are used to heat the substance to as high as even 1000 degree centigrade temperature or more.

describe some of the extraction methods and identify different types of mining. in order to use the resources at our disposal, we need to be able to get to them. this section introduces the different techniques used to extract or remove these resources.
titanium is a transition metal used in high quality alloys. it is extracted from its ore using first carbon and chlorine, then sodium or magnesium (both more reactive metals than titanium) to reduce the titanium(iv) chloride formed to titanium metal.
iron ore imports into china below are the top 15 suppliers from which china imported the highest dollar value worth of iron ore during 2019. within parenthesis is the percentage change in value for each supplying country. australia: us$61 billion (up 69.5% from 2015)
besides, india ranks 3rd in production of coal & lignite, 2nd in barites, 4th in iron ore, 5th in bauxite and crude steel, 7th in manganese ore and 8th in aluminium.' [8] india accounts for 12% of the world's known and economically available thorium . [16]
copper minerals and ore are found throughout the earth's crust. they occur in both sedimentary and igneous rocks. the outer 10 km of the crust contains 33 g of copper for every tonne of rock. this is not enough to make it commercially viable to extract the rock.
there are a number of iron ores. however, it is uneconomical to extract iron from most of the ores. two important ores used in extracting iron are hematite, fe 2 o 3 and magnetite, fe 3 o 4.first, these ores undergo several processes to remove the impurities. then

globally, around two billion tonnes of iron ore (average 62%) is used in the form of lumps/sinter/pellets to produce steel. however, the reserves of high grade ore are depleting rapidly due to which the adoption of beneficiation technologies such as sintering and pelletizing to utilise fine ore and low grade ore is attracting heightened attention in the industry.
the iron industry began to relocate to coal fields, which usually had iron ore nearby. developments elsewhere also helped to boost iron by stimulating demand, such as the increase in steam engines (which needed iron), which in turn boosted iron innovations as one industry bred new ideas elsewhere.
iron ore mining is buried in even bigger problems. until a couple of years ago, india was the world's third largest exporter of the mineral, earning $7 billion from it annually.
kudremukh is a flagship company under the ministry of steel, government of india, formed in 1976. it is the country's prestigious export oriented unit, with iron ore mining, filtration technology and production of high quality pellets. the company has a major
nickel occurs in ore bodies, and breaking down these ore bodies to extract nickel expends energy. producing nickel requires ample supplies of coal, electricity and crude oil. mines and blast furnaces utilize energy to extract nickel ores from the ground and process it into nickel.
