Bor Mine
The Bor mine is a large copper mine located in the east of Serbia in Bor District. Bor is one of the largest copper reserves in Serbia and in the world, having estimated reserves of 200 million tonnes of ore grading 1.5% copper. The area had been mined for gold as far back as at least the ancient Romans, but copper ore was only discovered, accidentally, in 1902. Local legend holds that a young local man, Paun Meždinović, was the discover of the first lump of copper ore, but it was industrialist Đorđe Vajfert who made the first formal exploitations - forming ''La Compagnie fran''ç''aise des mines de Bor, Concession St. George'' with French financing, in1903. As early as 1904, the mine employed around 80 miners and, during that year, 5,500 tons of copper ore were excavated, resulting in 774 tons of pure copper. In the first five years, the French company capital was increased from the initial 5.5 to 7 million French francs in gold. Copper was transferred to the nearest train st ...

Bor District
The Bor District ( sr, Борски округ, Borski okrug, ) is one of nine administrative districts of Southern and Eastern Serbia. It has a population of 123,848 inhabitants, according to the 2011 census results. The administrative center of the Bor district is the city of Bor and the judicial one, due to tradition, Negotin. History The Triballi dominated the region before the Roman conquest in the 1st century BC that weakened and subdued the Paleo-Balkan tribes. The Triballi, a Triballi-Dacian tribe, were defeated by the Roman army under Marcus Licinius Crassus, the consul of 30 BC. The region was organized into Moesia Inferior in 87 AD by Emperor Domitian. Hellenistic religious influence is attested through archeological findings in Rovine and Tamnič where Heracles was worshipped, a relief of Zeus, Herakles and Dionysos found in Bukovo. The Roman site of Selište with necropolis has been excavated in the village of Rogljevo. Silver and gold fibulae from 250 ...

Bullock Cart
A bullock cart or ox cart (sometimes called a bullock carriage when carrying people in particular) is a two-wheeled or four-wheeled vehicle pulled by oxen. It is a means of transportation used since ancient times in many parts of the world. They are still used today where modern vehicles are too expensive or the infrastructure favor them. Used especially for carrying goods, the bullock cart is pulled by one or several oxen. The cart is attached to an ox team by a special chain attached to yokes, but a rope may also be used for one or two animals. The driver and any other passengers sit on the front of the cart, while load is placed in the back. Traditionally, the cargo was usually agrarian goods and lumber. History The first indications for the use of a wagon (cart tracks, incisions, model wheels) are dated to around 4400 BC. The oldest wooden wheels usable for transport were found in southern Russia and dated to 3325 ± 125 BC. Evidence of wheeled vehicles appears from the mid ...

RTB Bor
Serbia Zijin Bor Copper, formerly known as RTB Bor, is a copper mining and smelting complex located in Bor, Serbia. History Formation and expansion The first geological explorations of copper ore in Bor area were conducted in 1897 and covered the area at the time called "Tilva Roš". The explorations were performed by the Serbian industrialist Đorđe Vajfert, who later provided investments of capital from France and set up a company called the "French Society of the Bor Mines, the Concession St. George". The company, with its headquarters in Paris, started operations on 1 June 1904. The French capital remained in Bor until the end of the World War II. 1951–1988: SFR Yugoslavia In 1951, the company's assets were nationalized by the Government of SFR Yugoslavia. Since then, the company Bor was in the state ownership. From 1951 until 1988, the company has changed its organizational structure, from the "organization of associated labor" to state-owned enterprise "RTB B ...

Sulfuric Acid
Sulfuric acid ( American spelling and the preferred IUPAC name) or sulphuric acid ( Commonwealth spelling), known in antiquity as oil of vitriol, is a mineral acid composed of the elements sulfur, oxygen and hydrogen, with the molecular formula . It is a colorless, odorless and viscous liquid that is miscible with water. Pure sulfuric acid does not exist naturally on Earth due to its strong affinity to water vapor; it is hygroscopic and readily absorbs water vapor from the air. Concentrated sulfuric acid is highly corrosive towards other materials, from rocks to metals, since it is an oxidant with powerful dehydrating properties. Phosphorus pentoxide is a notable exception in that it is not dehydrated by sulfuric acid, but to the contrary dehydrates sulfuric acid to sulfur trioxide. Upon addition of sulfuric acid to water, a considerable amount of heat is released; thus the reverse procedure of adding water to the acid should not be performed since the heat released ...

Froth Flotation
Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century. It has been described as "the single most important operation used for the recovery and upgrading of sulfide ores". The development of froth flotation has improved the recovery of valuable minerals, such as copper- and lead-bearing minerals. Along with mechanized mining, it has allowed the economic recovery of valuable metals from much lower grade ore than previously. Industries Froth flotation is applied to a wide range of separations. An estimated 1B tons of materials are processed in this manner annually. Mineral processing Froth flotation is a process for separating minerals from gangue by exploiting differences in their hydrophobicity. Hydrophobicity diffe ...

Smelter
Smelting is a process of applying heat to ore, to extract a base metal. It is a form of extractive metallurgy. It is used to extract many metals from their ores, including silver, iron, copper, and other base metals. Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind. The reducing agent is commonly a fossil fuel source of carbon, such as coke—or, in earlier times, charcoal. The oxygen in the ore binds to carbon at high temperatures due to the lower potential energy of the bonds in carbon dioxide (). Smelting most prominently takes place in a blast furnace to produce pig iron, which is converted into steel. The carbon source acts as a chemical reactant to remove oxygen from the ore, yielding the purified metal element as a product. The carbon source is oxidized in two stages. First, the carbon (C) combusts with oxygen (O2) in the air to produce carbon monoxide (CO). Second, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
