What is the importance of
rocks in our lives?
There are three such rocks and minerals that I can think of that play large roles Of these rock and minerals the three consist of gold graphite and coal These are very important in my life because I use each one everyday and respect the rocks and minerals for their contribution to everyday life In the main minerals have been extracted from deep levels subjected to some basic processing and then exported as ores without a great deal of beneficiation or fabrication For instance we do not have substantial gold or diamond manufactured products capabilities despite having huge natural resources The gap between mining and manufacturing

Gold Mineral information
data and localities
Gold is often panned from such deposits by taking advantage of its high density to wash away the lighter sediments from a pan or sluice Nuggets are almost exclusively hypogene in origin forming mostly in veins but can be somewhat modified in form and chemistry by weathering erosion and transport (Hough et ADVERTISEMENTS In this article we will discuss about - 1 Introduction to Ore Deposits 2 Origin of Ore Deposits 3 Types Introduction to Ore Deposits Minerals form chief source of all the industrial metals and non-metals The commonly used metals like aluminum copper iron lead zinc etc are all manufactured using minerals as raw materials
Chapter 1
Some of the most important accumulations of metals such as gold silver and copper are produced by igneous and metamorphic processes May 24 2019Pure elemental gold is 24 karat while 18 karat gold is 75 percent pure gold 14 karat gold is 58 5 percent pure gold and 10 karat gold is 41 7 percent pure gold The remaining portion of the metal usually used in gold jewelry and items is silver but items may also consist of other metals or a combination of metals such as platinum copper
Importance Of Minerals Such As Gold
Iron Zinc and Magnesium Vitamins
Iron zinc and magnesium belong to a class of nutrients called minerals Iron and zinc are trace minerals which means you need only small amounts of them in your body to function properly Magnesium is a major mineral which is named for the fact that your body Minerals are important materials in our technological civilization and a single mineral may have many unrelated uses The mineral corundum provides a good example Corundum is an extremely hard substance Small bits of corundum are part of the rock called emery which has been used since ancient times as an abrasive to cut and grind metal and

The Importance Of Geology
Jan 12 2013One of the most important areas of geology is economic geology in which we have to study how to locate the minerals and fossils in the earth Locating important minerals such as gold oil and coal is extremely important for man's survival In order to learn how to locate these important minerals we have to study the field of geology Minerals can be identified by their physical characteristics The physical properties of minerals are related to their chemical composition and bonding Some characteristics such as a mineral's hardness are more useful for mineral identification Color is readily observable and certainly obvious
