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 250–32 ...

Copper
Copper is a chemical element with the symbol Cu (from la, cuprum) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color. Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling silver used in jewelry, cupronickel used to make marine hardware and coins, and constantan used in strain gauges and thermocouples for temperature measurement. Copper is one of the few metals that can occur in nature in a directly usable metallic form ( native metals). This led to very early human use in several regions, from circa 8000 BC. Thousands of years later, it was the first metal to be smelted from sulfide ores, circa 5000 BC; the first metal to be cast into a shape in a mold, c. 4000 BC; and the first metal to be purposely alloyed with another metal, tin, to create ...

Mining
Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef, or placer deposit. The exploitation of these deposits for raw material is based on the economic viability of investing in the equipment, labor, and energy required to extract, refine and transport the materials found at the mine to manufacturers who can use the material. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay. Mining is required to obtain most materials that cannot be grown through agricultural processes, or feasibly created artificially in a laboratory or factory. Mining in a wider sense includes extraction of any non-renewable resource such as petroleum, natural gas, or even water. Modern mining processes involve prospecting for ore bodies, analysis of the profit potential of a proposed mine, extraction of the desired materials, an ...
