Research task 1 5.1- define the terms mineral and ore with reference to economic and non-economic deposits of natural resources The term ‘ore minerals’ is commonly referred to as economic minerals Mineral: naturally occurring compounds. Rocks are mixtures of various minerals. Most minerals are lattice structures‚ both ionic and covalent. Economic minerals have been divided into two main categories: Metalliferous minerals- mined to extract a metal Industrial mineral- either has some direct practical

1. What is geology and what are the two types of geology? Geology: is the act of studying earth or other solid celestial bodies and how they were formed and what they are comprised of. There are two main types of geology: Physical: the study of minerals and how they were formed. Historical: the study of the story of solid celestial bodies and the evolution of the natural elements/features that comprise them. 2. Explain how a hypothesis is different from a theory. All theories were once hypothesis

De Beers is currently being faced with some new challenges that are making it necessary for us to consider a change in the way we do business. With recent turmoil in Western Africa‚ where illicit diamonds are beginning to come from war torn villages‚ and other sources of diamonds being found in Russia and Australia‚ it is clear that we need to begin to move into the U.S. market. However‚ legally‚ De Beers is in violation of the U.S. antitrust laws and is therefore being prohibited from selling directly

you know... Chalcopyrite was the mineral upon which Bronze Age civilizations were built. Within the last century‚ it also became the mineral foundation for our modern electrical age. Our primary source of copper‚ chalcopyrite’s name comes from the Greek words ‘chalkos’ and ‘pyrites’‚ which respectively mean ‘copper’ and ‘striking fire’. With its metallic luster and bright golden color‚ chalcopyrite can fool people into thinking it is gold. It is one of two minerals‚ the other being pyrite‚ that are

1888‚ De Beers followed a strategy of supply control. In addition to mining its own diamonds‚ it bought diamonds from other producers and had what it called the "central selling organization‚" controlling some 90% of the world’s diamonds. Its tight control over such a vast amount of supply enabled De Beers to keep prices high for a commodity that is neither particularly scarce nor useful. If a competitor offered diamonds on the market outside of De Beers’ central selling organization‚ De Beers would

Weathering Weathering is the breaking down of Earth’s rocks‚ soil and minerals through direct contact with the planet’s atmosphere. Weathering occurs in situ or “with no movement” and thus should not be confused with erosion‚ which involves the movement of rock and minerals by agents such as water‚ ice‚ wind and gravity. In addition‚ weathering is the effect of atmospheric exposure to man-made structures and materials. Two important classification of weathering processes exist – physical and
