Mineral: K-Feldspar K-Feldspar‚ also known as Potassium Feldspar or orthoclase‚ is the most common rock-forming mineral. It covers up about 60% of the Earth’s crust (Feldspar). Feldspar crystalizes from magma which is found in both extrusive and intrusive igneous rocks as well as metamorphic rocks (wisconsingeologicalsurvey.org). They form at medium to high temperature and at certain depths. They may also be found in some sedimentary rocks. This mineral is widespread and can mostly be found

INTRODUCTION Flotation is a process in mineral treatment and mining which separates mixtures by lifting creation minerals at or on a water process. It was developed on a commercial scale early in the 20th century to remove very fine particles that formerly had gone to waste in gravity concentration plants. This method separates and concentrates ores by altering their surfaces which then emphasize the difference in wettabilities of different minerals. When air is blown through the mixture‚ hydrophobic

and Mining The principal law is the Minerals Act (1967)‚ last amended in 2002 by Minerals Act No. 5. The act governs onshore and offshore exploration‚ mineral production‚ mineral trading‚ oredressing‚ transport and export of minerals‚ other than petroleum. The Department of Primary Industry and Mining (“DPIM”) is empowered to administer the Minerals Act and to issue ministerial regulations. DPIM also provides technical assistance in exploration‚ mining‚ mineral processing and metallurgical activities

Geological process affect our everyday life in that everything that we see or touch has some form of minerals in them. Our laptops‚ tablets‚ televisions all have minerals in them. These minerals are known as “rare Earth minerals”. Our homes need to have the best materials to ensure safety‚ so the hardest rocks or minerals are used. Even things that one normally would not think contains minerals‚ such as toothpaste and facial care products. http://geology.com/articles/rare-earth-elements/ http://geology

using mineral nutrient solutions‚ in water‚ without soil. It is not a new invention‚ but its popularity is currently increasing drastically. People are now using this process of growing plants‚ flowers‚ and vegetables without soil in their homes‚ where previously it was mostly used just by professional gardeners. Because of the ’hydro’ in the name‚ it is a common misconception that the plants are being grown in water instead of soil. They are in fact grown in liquid‚ but it is a mineral nutrient

Certain natural factors like the presence of coastline‚ a very good natural harbour at Marmugao and a number of navigable perennial rivers have promoted the economic exploitation of mineral deposits. Transport of ores by barges is the cheapest option as compared to road and rail transport. Goa is a major iron ore exporting state and over 60% of Country’s iron ore export is from Goa.
