Conflict Mineral
The eastern Democratic Republic of the Congo (DRC) has a history of conflict, where various armies, rebel groups, and outside actors have profited from mining while contributing to violence and exploitation during wars in the region. The four main end products of mining in the eastern DRC are tin, tungsten, tantalum, and gold, which are extracted and passed through a variety of intermediaries before being sold to international markets. These four products, (known as the 3TGs) are essential in the manufacture of a variety of devices, including consumer electronics such as smartphones, tablets, and computers. Some have identified the conflict as significantly motivated by control over resources. In response, several countries and organizations, including the United States, European Union, and OECD have designated 3TG minerals connected to conflict in the DRC as conflict minerals and legally require companies to report trade or use of conflict minerals as a way to reduce incentives ...

The Washington Post
''The Washington Post'' (also known as the ''Post'' and, informally, ''WaPo'') is an American daily newspaper published in Washington, D.C. It is the most widely circulated newspaper within the Washington metropolitan area and has a large national audience. Daily broadsheet editions are printed for D.C., Maryland, and Virginia. The ''Post'' was founded in 1877. In its early years, it went through several owners and struggled both financially and editorially. Financier Eugene Meyer purchased it out of bankruptcy in 1933 and revived its health and reputation, work continued by his successors Katharine and Phil Graham (Meyer's daughter and son-in-law), who bought out several rival publications. The ''Post'' 1971 printing of the Pentagon Papers helped spur opposition to the Vietnam War. Subsequently, in the best-known episode in the newspaper's history, reporters Bob Woodward and Carl Bernstein led the American press's investigation into what became known as the Watergate scandal ...

Cobalt Sulfate
Cobalt(II) sulfate is any of the inorganic compounds with the formula CoSO4(H2O)x. Usually cobalt sulfate refers to the hexa- or heptahydrates CoSO4.6H2O or CoSO4.7H2O, respectively. The heptahydrate is a red solid that is soluble in water and methanol. Since cobalt(II) has an odd number of electrons, its salts are paramagnetic. Preparation, and structure It forms by the reaction of metallic cobalt, its oxide, hydroxide, or carbonate with aqueous sulfuric acid: :Co + H2SO4 + 7 H2O → CoSO4(H2O)7 + H2 :CoO + H2SO4 + 6 H2O → CoSO4(H2O)7 The heptahydrate is only stable at humidity >70% at room temperature, otherwise it converts to the hexahydrate. The hexahydrate converts to the monohydrate and the anhydrous forms at 100 and 250 °C, respectively. :CoSO4(H2O)7 → CoSO4(H2O)6 + H2O :CoSO4(H2O)6 → CoSO4(H2O) + 5H2O :CoSO4(H2O) → CoSO4 + H2O The hexahydrate is a metal aquo complex consisting of octahedral o(H2O)6sup>2+ ions associated with sulfate ...

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 ...

Cobalt Carbonate
Cobalt(II) carbonate is the inorganic compound with the formula CoCO3. This reddish paramagnetic solid is an intermediate in the hydrometallurgical purification of cobalt from its ores. It is an inorganic pigment, and a precursor to catalysts. Cobalt(II) carbonate also occurs as the rare red/pink mineral spherocobaltite. Preparation and structure It is prepared by combining solutions cobaltous sulfate and sodium bicarbonate: :CoSO4 + 2 NaHCO3 → CoCO3 + Na2SO4 + H2O + CO2 This reaction is used in the precipitation of cobalt from an extract of its roasted ores. CoCO3 adopts a structure like calcite, consisting of cobalt in an octahedral coordination geometry. Reactions Like most transition metal carbonates, cobalt carbonate is insoluble in water, but is readily attacked by mineral acids: :CoCO3 + 2 HCl + 5 H2O → o(H2O)6l2 + CO2 It is used to prepare many coordination complexes. The reaction of cobalt(II) carbonate and acetylacetone in the presence ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
