Coal fossil fuel.

Coal is a fossil fuel. Coal is a combustible sedimentary rock, formed from the organic sediment, which originated from the remains of plants and has developed through geological time. Elements consisting of carbon, hydrogen and oxygen. Coal is also an organic rock that has the properties of the complex physics and chemistry. empirical formula such as C137H97O9NS to C240H90O4NS bitumen and anthracite for. Coal formation requires certain conditions and only occur in a particular era in the history of geology. Carboniferous Period, roughly 340 million years ago, is the formation of the most productive coal and almost all coal mines (coal black) who live in the northern hemisphere is formed. In the Permian Period, about 270 Mya, is also an economical form of coal deposits in the southern hemisphere, like Australia, and continues until the Tertiary Period (70-13 Mya) in the other hemisphere. Almost all coal-forming plant origin. Coal mining coal mining from the earth for human use in many coal mines in Indonesia and even the world. Coal used as fuel, can also be used to make coke for the manufacture of many more baja.dan their role, there are many coal mines in Indonesia, especially in Kalimantan

largest diamond mine

The world's biggest diamond mine located in Australia, Argyle diamond mine bernamaTambang located in the north of Western Australia. diamond was discovered in 1976 in a river. Diamond has been eroded from an ancient volcano that erupted 1.1 million years ago. When a volcano cools, igneous rock channel residual lintasanya very deep and is 2 kilometers. Diamonds formed at very high temperatures in this rock, and now this mountain contains one of the world's richest diamond deposits. This mine is a large gaping open pit in the ground. Every day about 25,000 tonnes of rock excavated. It produces about 23 kilograms of diamonds. Each year about 8.5 tons of diamonds have been sold. Argyle is the only diamond mine in Australia. The production is very high which is now Australia has become the fifth largest diamond exporter in the world. Ordering: Russia, Botswana, South Africa, Zaire, and Australia. Transparent good quality diamonds used for jewelry. Another type of diamond used in industry. Diamonds are used for cutting metal or stone that is very hard. Most diamonds used for jewelry are cut and formed in Bombay, India. Argyle mine employs 700 people to mine diamonds. They work for twelve hours every day. This work is difficult because diamonds are very small and very precious. Most workers live in the city of Perth which is located 1600 kilometers south of the mining area. The workers are in a plane flying from Perth to mining. They work for two weeks. Then they go home by plane to Perth for two weeks

petroleum formationoil

Fossil petroleum because we can see in terms of fossilization but scientists beberepa bersependapat that petroleum does not include fossil fuels, why do so because of the formation of oil at high temperature and pressure so that the fossil has not been formed since been destroyed by the extremely high temperatures and is therefore not absolute oil / absolute can be said of fossils. But many said oil as fossil fuels, derived from the rubble of the remains of plants and large networks hewan.Sebagian destroyed organic material into gas that is lost to the atmosphere, but at the time of the gas produced is very large, some stayed and stuck in a sediment . Marine Microorganisms were destroyed, and then form the oil and natural gas. black liquid which is a mixture of different types of hydrogen-carbon molecule, so that when burned will produce carbon dioxide gas (CO2) and water (H2O). Petroleum is found beneath the earth's surface at a depth of 500 - 2500 m. For that crude oil must be pumped out and then streamed to the installation of oil refineries to be processed to obtain various types of fuel oil for example, (gasoline, diesel, kerosene etc). Besides being used as fuel, petroleum is also used as raw material for plastics and chemical industries. As a source of energy, oil suitable for transport purposes, eg for vehicle fuel, because it has a high energy content per volume

nickel-producing country

Nickel laterite is an important mineral source, contributing 40% of world nickel production. Lateritic nickel deposits are formed from the weathering of ultramafic host rock type. Generally formed in the tropical climate to a sub-tropical. Today, most nickel laterite formed in the equatorial region. Countries lateritic nickel producer in the world including New Caledonia, Cuba, Philippines, Indonesia, Columbia and Australia. The "laterite" term could be interpreted as a sediment rich in iron oxide, silica poor and intensive elements are found in sediments in a tropical climate lapukan (Eggleton, 2001). There also are interpreted as sediment lapukan containing nickel laterite nickel and economical to mine. Nickel laterite deposit base rock is ultramafic rock; generally harsburgit (Peridotit ortopiroksen rich element), dunite and the types of Peridotit.

Chemical Process Formation of Nickel

Nickel formed with silicate minerals rich in elements Mg (ex; olivine). Olivine is a mineral which is unstable during weathering took place. Saprolite is the first weathering product, leaving at least 20% of the original fabric of the rock (parent rock). Boundary between bedrock, saprolite and wathering front unclear and even changes gradasional. Laterite nickel deposits are characterized by the existence of speroidal weathering along joints and fractures (boulder saprolite). During weathering progresses, Mg silicates are soluble and dissolve with groundwater. This causes the fabric of parent rock is totally change. As a result, Fe-Oxide dominated by forming horizontal layers above the saprolite, which we now know as limonite. It is true that nickel is associated with Fe-Oxide mainly of type Goethite. The average nickel amounted to 1.2%

Genesis of Nickel Laterite

Nickel deposits generally formed on ultramafic rocks containing high Fe in olivine and nickel-yield between 0.2% - 0.4% wt. The mineralogy of nickel laterite can be divided into three categories (Brand et al., 1998) a. Hydrous silicate DepositsProfiles of this type of vertical from bottom to top: Ore horizon in saprolite layer (Mg-Ni silicate), Nickel grade between 1.8% - 2.5%. In this zone developed box-works (what tuh ..), veining, relic structure, fracture and grain boundaries and can form mineral-rich Nickel; garnierite (max. 40% Ni). Ni dissolved (Leached) from the phase of limonite (Fe Oxyhydroxide) and deposited with hydrous silicate minerals or substitute elements of Mg in an altered serpentinite (Pelletier, 1996). So, although the nickel laterite is a product of weathering, but it can be said also that the supergene enrichment process is very important in the formation and economic value of hydrous silicate precipitated this. This type can be found in several places such as in New Caledonia, Indonesia, Philippines.Dominika and Columbia. b. Silicate Clay Deposits In this sediment type, Si is only partially dissolved by the groundwater. The remaining will join with Fe, Ni, and Al to form clay minerals (clay minerals) such as Ni-rich Notronite in the middle of the saprolite profile (see profile). Ni-rich serpentine also can be replace by smectite or quartz if the profile of this deposit in a long time stay in contact with groundwater. Ni grade of these deposits is lower than Hydrosilicate deposit (1.2%; Brand et all, 1998). c. Oxide Deposits The last type Oxide. Profile below shows Protolith of harzburgitic type peridotites (Mostly minerals olivine, serpentine, pyroxene), are very susceptible to weathering, especially in the tropics. Formed thereon is formed near surface saprolite and limonite and ferricrete (surface) (see profile). In this type of deposit oxide, nickel associated with Goethite (FeOOH) and Mn Oxide. In addition, Nickel laterite is very rarely or not at all formed in carbonate rocks contain mineral talc.

MINERAL ZEOLITE

This mineral is a group of compounds various kinds of mineral alumino silicate hydrate with alkali metals. Minerals included in the group of zeolite tuff, formed from volcanic ash sedimentation changed. To be able to use the zeolite should have certain specifications relating to this qualification is determined by the absorption of the zeolite, cation exchange capacity (CEC) and the catalyst. Therefore, to memmperoleh zeolite with high capability required some processing, among others: 1. Preparation This stage aims to obtain sizes of products in accordance with their intended use. Preparation phase consists of destroying the (destroyed), for milling (grinding). 2. Activation This process aims to improve the specific properties of the zeolite by removing the elements of impurities and evaporate the water trapped in the pores of the zeolite crystal. There are two ways commonly used in zeolite activation process, namely heating at a temperature of 200-400 º C for 2-3 hours, and chemical reagents by using NaOH or H2SO4. 3. Modification Process modifications are intended to change the surface properties of natural zeolite with a coating of organic polymers (synthetic and natural) in the zeolite. A. MARKET OUTLOOK Zeolites used in agriculture, animal husbandry, fisheries, industry, environmental health and building materials. Utilization of broad dimensions, implications for the potential demand is large enough. Request zeolite today come from countries Korea, Singapore and Japan. Meanwhile, domestic demand no less potential. Dimensions ample use of various aspects of life, can be predicted perminttan zeolite will increase along with increasing prosperity and the national economy. One of the central reserves of zeolite with a fairly large volume in Tasikmalaya is part of the southern mountainous district stretches from Cikalong, Karangnunggal until Cipatujah. B. DEVELOPMENT STRATEGY Exploitation of zeolite in Tasikmalaya are mostly done by people, but unfortunately mine management do not meet the rules applicable to mining activities. The weakness is most prominent in zeolite mining system that the society is the lack of attention to sustainability, waste resources, and low added value gained from such mining efforts. Meanwhile, the added value gained from the mining business was not optimal. This is caused by mineral processing is done outside the region, namely in Padalarang. Meanwhile, because the mining done by people too much wild, do not have permission then the levies or taxes from the mine into a lot of materials that do not terpungut. The ideal distribution channel, not too long, the process is done around the location of mineral deposits. In the concept of the ideal distribution network, there should be no raw material out of Tasikmalaya. Just finished goods, or at least a half-finished out of Tasikmalaya. Also on the ideal distribution network is likely to put the miners as the owner of the zeolite powder manufacturing plant or other product form.New!
