Bauxite beneficiation plant applied in Africa
Bauxite is a rock composed mainly of aluminum oxide and aluminum hydroxide minerals. These might include: gibbsite, boehmite and diaspore. The rock usually includes other materials such as iron hydroxides, clay, silt and free silica. It most often occurs as a residual soil material in tropical and subtropical areas. It is the primary source of aluminum. Aluminum comes from Canada, China, Australia, India, Brazil, Guinea, Jamaica and Russia.
SBM has 30 years experience for designing and manufacturing all kinds stone crushers from primary crushing to fineness crushing. We also supply all kinds crushing plant for ore beneficiation, stone crushing, bauxite beneficiation plant, coal, cement and recycling industry
SBM, the professional grinding mill manufacturer, has exported our grinding mill plant for powder making to many countries. SBM grinding mill plant is for coarse powder making to ultrafine powder grinding. It is an ideal equipent for calcium carbonate, coal, cement, gypsum, limestone and so on.
Philippines is rich in mineral resources. Most of the country's metallic minerals, including gold, iron ore, lead, zinc, chromite, and copper, are drawn from major deposits on the islands of Luzon and Mindanao. Smaller deposits of silver, nickel, mercury, molybdenum, cadmium, and manganese occur in several other locations. The Visayas are the principal source of nonmetallic minerals, including limestone for cement, marble, asphalt, salt, sulfur, asbestos, guano, gypsum, phosphate, and silica.
In Africa, very few government officials and civil servants perform services for free. You cannot get your birth certificate or passport unless you grease the palm of officials. You cannot get good education for your kid unless you pay a bribe. You cannot obtain electricity meter for your house unless you pay a bribe. You cannot get your goods out from the harbour unless you pay kickback. Anything involving signing of documents involves paying inducements. In Africa you can hardly find someone who has not paid bribe before either willingly or unwillingly. To receive attention barite processing machine when you are sick you need to grease the palm of hospital officials.
In Ghana, officials illegally charge 15 and 150 Ghana cedis for a birth certificate and a passport respectively. Again in Ghana Police officers openly ask bus and taxi drivers to pay bribe before they are allowed to cross mounted road blocks. Customs officials adopt all manner of tactics in order to collect money from importers and exporters before their goods are allowed to leave the ports.
Most projects in Africa are carried out by corrupt contractors who collude and connive with public officials to inflate project cost in order to enrich themselves. As a result every project carried out cost three times the usual cost and it is always the tax payers who bear the brunt of it. Due to corruption, project inspectors fail to do their job and allow substandard work to be done at the expense of the people and the nation.
In Africa, it is totally useless to bid for contracts because contracts are awarded to the contractors who are able to pay the biggest bribe. In most countries there are no announcements for tenders rather contracts are awarded to companies who secretly pay large sums of commission to government officials.
Bauxite mining
Open gold ore processing mining is used to get bauxite. The water in bauxite is taken out of the ore. This leaves a white powder that is called alumina which is another name for aluminum oxide. Alumina is made into aluminum.
Eighty percent of world bauxite production, mainly from large blanket type deposits is from surface mines, with the rest, mainly from Southern Europe and Hungary, from underground excavations. On some surface deposits there is no overburden, and on others, the bauxite may be covered by 70 metres or more of rock and clay. Deposits that are hardened may require blasting in order to release the ore. Once the bauxite is loosened into manageable pieces it is generally loaded into trucks or railroad cars and transported to crushing or washing plants or to stockpiles. Underground bauxite mines are used to exploit pockets or beds of deposit between layers of carbonic rock. Water in flow is a problem in most underground operations and dewatering shafts are often drilled before mining begins.
