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

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

demand for minerals to create mobile phones‚ is becoming more than ever. One of the main minerals used in creating mobile phones‚ is tin. Tin is generally used as the basic outside structure of a mobile phone. This essay will conduct of several topics‚ such as location of minerals‚ the techniques used to extract the mineral from the ore‚ what tin is actually used for in mobile phones‚ and ways how mining companies‚ can stop from damaging the environment.

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

been applied to gold ore refractory and refractory concentrates. This process involves the oxidation of sulfide‚ ferrous‚ and sometimes carbon containing minerals in order to liberate the gold trapped within. This process is possible by use of several bacterial strains which gain energy from the oxidation of reduced sulfur and ferrous minerals. There are three main bioleaching techniques: heap bioleaching‚ bioreactors and vats. Optimizing the biooxidation of gold ore involves numerous physicochemical
