3.MINERALS AND POWER RESOURCES A naturally occurring substance having a definite chemical composition is called a mineral.Minerals are found in certain areas only and not every where. Minerals are formed in different conditions and human activities do not play any role in their formation. Instead only natural processes are involved . Minerals are identified on the basis of their physical properties like colour ‚density ‚hardness and chemical properties like solubility. On the basis of composition

processes. It alters the intrinsic properties such as chemical structure‚ composition and density of the minerals that the rock is made up of. A rock’s susceptibility to Chemical Weathering depends on the stability of the minerals in it. Rock is composed of minerals that are generally quite stable at the time of formation. When there is variation in the surrounding environment‚ some minerals tend to become unstable. Chemical reactions take place when the rock comes into contact primarily with water

Part 2 Deep ocean mining is an alternative to land mining in search of minerals such as copper‚ gold‚ manganese or cobalt among other minerals. The minerals on land are being depleted owing to the increasing demand for these minerals‚ and this makes the deep sea bed an alternative to the exploitation of minerals. The fact that the water bodies cover a huge part of earth’s surface makes deep sea mining even more viable option. It is a discussion

controls toward this problem‚ while ensuring the smooth running of the industries‚ and also helping to create strong economy and employment. The world of today could not exist without mineral products. Canada produces about 60 minerals and ranks first among producing countries1. As well‚ Canada is the largest exporter of minerals‚ with more than 20 per cent of production shipped to world markets2. In a typical year‚ the mining industry is responsible for almost 20 per cent of Canada’s total export earnings3

14-1 Notes What are Mineral Resources? * Nonrenewable Resources: a concentration of naturally occurring material in or on the earth’s crust that can be extracted and processed at an affordable cost. Non-renewable resources are mineral and energy resources such as coal‚ oil‚ gold‚ and copper that take a long period of time to produce. * Metallic Mineral Resources – iron‚ copper‚ aluminum * Nonmetallic Mineral Resources – salt‚ gypsum‚ clay‚ sand‚ phosphates‚ water and soil. * Energy

Zirconium is a chemical element with the symbol Zr‚ atomic number 40 and atomic mass of 91.224. The name of zirconium is taken from the mineral zircon‚ the most important source of zirconium. It is a lustrous‚ grey-white‚ strong transition metal that resembles titanium. Zirconium is mainly used as a refractory and opacifier‚ although minor amounts are used as alloying agent for its strong resistance to corrosion. Zirconium forms a variety of inorganic and organometallic compounds such as zirconium
