Some examples of minerals are given below, pick out the one that is not a non-metallic mineral
Give two examples of non- metallic mineral fuels from the options given below:
Which of these methods are widely used for extracting minerals
Correct Answer :- d
Explanation : Mineral extraction sites, which include strip mines, quarries, and underground mines, contribute to surface and groundwater pollution, erosion, and sedimentation. The mining process involves the excavation of large amounts of waste rock to remove the desired mineral ore. The ore is then crushed into finely ground tailings for chemical processing and separation to extract the target minerals. After the minerals are processed, the waste rock and mine tailings are stored in large, above-ground piles and containment areas.
Drilling fluids, which contain many different components, can be oil based, consisting of crude oil or other mixtures of organic substances such as diesel oil and paraffin oils, or water based, consisting of freshwater or seawater with bentonite (clay) and barite (BaSO4).
From the following options given, pick out the correct reason as to why impurities should be removed from mineral ores?
The ores contain a lot of impurities that need to be filtered to obtain useful material. The filtration of these impurities from ores is known as concentration.
Apart from the given two methods, name one more method that is used for Extraction of Minerals
Name the process of taking out minerals from rocks buried under the surface of the earth.
Name this process of extracting minerals. Here minerals that lie at shallow depths are taken out by removing the surface layer from an open pit.
From the image attached identify the method used to extract minerals. Deep bores have to be made to reach mineral deposits that lie at great depths.
Name the method used to extract Petroleum and natural gas wherein deep wells are bored to take them out.
Name the country with the largest reserve of iron ore.
Obviously Russia , far East region of Russia has many minerals , natural gas etc .Recently India PM visited the far East region .China also visited the region and Russia also proposed a 4000km natural gas pipe line to eastern China recently.
A few examples of minerals found in different areas are given below. Pick out the one that is not an example of mineral found in igneous and metamorphic rocks
In nature, manganese is concentrated in various manganese rocks of sedimentary.
Listed below are a few examples of minerals found in different areas . Pick out the one that is not an example of mineral found in sedimentary strata.
Nickel is obtained from two main types of deposits from the mineral garnierite (Ni-silicate) in nickel-rich laterite formed by weathering of ultramafic rocks in tropical climates. It also is mined from Ni-sulfide concentrations, mainly from pentlandite in igneous mafic rocks.
Name the country where there are no known mineral deposits in the world
Name the two countries known to have large iron ore deposits in Asia.
Which among the following is a leading producer of tin in the world?
China tops the list in tin production as the country produces 125,000 metric tons each year, while Indonesia produces 84,000 metric tons, Peru 23,700 metric tons, Bolivia 18,000 metric tons.
Which country leads in production of lead, antimony and tungsten?
China is the leading producer of more than half of the minerals listed in the British Geological Survey.Thanks to cheap labor, high demand and capital, China taps its resources more aggressively than any nation.While total reserves may in the longer term mean more, the country that manages the supply of output controls in the short term.In terms of production as per last survey China's production stood at 1851000 tonnes in lead, 52000 tonnes of Tungsten, and 129831 tonnes of Antimony

leading tin producers. China also leads in production of
lead, antimony and tungsten. Asia also has deposits of
manganese, bauxite, nickel, zinc and copper.
From the given countries, which one does not have large deposits of iron ore in the world?
