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. Location of Minerals The mineral known as

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

The ore is grinding into small pieces by means of grinding medium (the steel ball‚ steel forging‚ and steel bar). The purpose is to make useful minerals and gangue mineral composition of ore to dissociation maximum‚ to provide size to meet the requirements of beneficiation process materials. Grinding is a very important job in dressing plant and grinding product quality will directly influence the classification index. The grinding process is a high energy consumption process. Therefore‚ to improve
