Tribute Mining
Tribute mining is an arrangement by which a person, partnership or company works a mine or part of a mine, under a tribute agreement with the titleholder of that mine, and either pays to or receives from the titleholder a proportion of the production of the mine or of the value of the production. Miners working in this way are known as tribute miners or tributers, and the mine is said to be worked 'on tribute'. The arrangement differs from conventional contracting and employment, both in its nature and its origins. A tributer is distinguished, from both an independent contractor and employee, in that the tributer takes over the running of the mine, or an agreed part of it, and is remunerated in a specific manner. The origins of tribute mining lie in the Stannaries of Cornwall and Devon, and the Stannary laws. John Taylor (1779-1863), a mining engineer, left a detailed description of how tribute mining was practiced, in the tin and copper mines of Cornwall and Devon during the 19t ...

Stannary
A stannary was an administrative division established under stannary law in the English counties of Cornwall and Devon to manage the collection of tin coinage, which was the duty payable on the metal tin smelted from the ore cassiterite mined in the region. In Cornwall, the duty was passed to the Duchy of Cornwall; in Devon to the Crown. With the abolition of tin coinage in 1838 (following extensive petitioning by the Cornish tin industry for simplification of the taxation rules), the principal purpose of the stannaries ceased. In Cornwall, however, they retained certain historic rights to appoint stannators to the Cornish Stannary Parliament. Etymology The word ‘stannary’ is derived from the Middle English ''stannarie'', through Medieval Latin ''stannaria'' (‘tin mine’), ultimately from Late Latin ''stannum'' (‘ tin’) ( cf. the symbol for the chemical element Sn). The native Cornish word is ''sten'' and tin-workings ''stenegi''. In Cornwall There were four Co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trade Union
A trade union (labor union in American English), often simply referred to as a union, is an organization of workers intent on "maintaining or improving the conditions of their employment", ch. I such as attaining better wages and benefits (such as holiday, health care, and retirement), improving working conditions, improving safety standards, establishing complaint procedures, developing rules governing status of employees (rules governing promotions, just-cause conditions for termination) and protecting the integrity of their trade through the increased bargaining power wielded by solidarity among workers. Trade unions typically fund their head office and legal team functions through regularly imposed fees called ''union dues''. The delegate staff of the trade union representation in the workforce are usually made up of workplace volunteers who are often appointed by members in democratic elections. The trade union, through an elected leadership and bargaining committee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chromite
Chromite is a crystalline mineral composed primarily of iron(II) oxide and chromium(III) oxide compounds. It can be represented by the chemical formula of FeCr2O4. It is an oxide mineral belonging to the spinel group. The element magnesium can substitute for iron in variable amounts as it forms a solid solution with magnesiochromite (MgCr2O4). A substitution of the element aluminium can also occur, leading to hercynite (FeAl2O4). Chromite today is mined particularly to make stainless steel through the production of ferrochrome (FeCr), which is an iron-chromium alloy. Chromite grains are commonly found in large mafic igneous intrusions such as the Bushveld in South Africa and India. Chromite is iron-black in color with a metallic luster, a dark brown streak and a hardness on the Mohs scale of 5.5. Properties Chromite minerals are mainly found in mafic-ultramafic igneous intrusions and are also sometimes found in metamorphic rocks. The chromite minerals occur in laye ...

Artisanal Miner
An artisanal miner or small-scale miner (ASM) is a subsistence economy, subsistence miner who is not officially employed by a List of mining companies, mining company, but works independently, mining minerals using their own resources, usually by hand. Small-scale mining includes enterprises or individuals that employ workers for mining, but generally still using manually-intensive methods, working with hand tools. Artisanal miners often undertake the activity of mining seasonally – for example crops are planted in the rainy season, and mining is pursued in the dry season. However, they also frequently travel to mining areas and work year-round. There are four broad types of ASM: permanent artisanal mining, seasonal (annually migrating during idle agriculture periods), rush-type (massive migration, pulled often by commodity price jumps), and shock-push (poverty-drive, following conflict or natural disasters). ASM is an important socio-economic sector for the rural poor in ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zimbabwe
Zimbabwe (), officially the Republic of Zimbabwe, is a landlocked country located in Southeast Africa, between the Zambezi and Limpopo Rivers, bordered by South Africa to the south, Botswana to the south-west, Zambia to the north, and Mozambique to the east. The capital and largest city is Harare. The second largest city is Bulawayo. A country of roughly 15 million people, Zimbabwe has 16 official languages, with English, Shona language, Shona, and Northern Ndebele language, Ndebele the most common. Beginning in the 9th century, during its late Iron Age, the Bantu peoples, Bantu people (who would become the ethnic Shona people, Shona) built the city-state of Great Zimbabwe which became one of the major African trade centres by the 11th century, controlling the gold, ivory and copper trades with the Swahili coast, which were connected to Arab and Indian states. By the mid 15th century, the city-state had been abandoned. From there, the Kingdom of Zimbabwe was established, fol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gold Mining
Gold mining is the extraction of gold resources by mining. Historically, mining gold from alluvial deposits used manual separation processes, such as gold panning. However, with the expansion of gold mining to ores that are not on the surface, has led to more complex extraction processes such as pit mining and gold cyanidation. In the 20th and 21st centuries, most volume of mining was done by large corporations, however the value of gold has led to millions of small, artisanal miners in many parts of the Global South. Like all mining, human rights and environmental issues are common issues in the gold mining industry. In smaller mines with less regulation, health and safety risks are much higher. History The exact date that humans first began to mine gold is unknown, but some of the oldest known gold artifacts were found in the Varna Necropolis in Bulgaria. The graves of the necropolis were built between 4700 and 4200 BC, indicating that gold mining could be at least ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Underground Hard-rock Mining
Underground hard-rock mining refers to various underground mining techniques used to excavate "hard" minerals, usually those containing metals, such as ore containing gold, silver, iron, copper, zinc, nickel, tin, and lead. It also involves the same techniques used to excavate ores of gems, such as diamonds and rubies. Soft-rock mining refers to the excavation of softer minerals, such as salt, coal, and oil sands. Mine access Underground access Accessing underground ore can be achieved via a decline (ramp), inclined vertical shaft or adit. *Declines can be a spiral tunnel which circles either the flank of the deposit or circles around the deposit. The decline begins with a box cut, which is the portal to the surface. Depending on the amount of overburden and quality of bedrock, a galvanized steel culvert may be required for safety purposes. They may also be started into the wall of an open cut mine. *Shafts are vertical excavations sunk adjacent to an ore body. Shafts a ...

Strike And Dip
Strike and dip is a measurement convention used to describe the orientation, or attitude, of a planar geologic feature. A feature's strike is the azimuth of an imagined horizontal line across the plane, and its dip is the angle of inclination measured downward from horizontal. They are used together to measure and document a structure's characteristics for study or for use on a geologic map. A feature's orientation can also be represented by dip and dip direction, using the azimuth of the dip rather than the strike value. Linear features are similarly measured with trend and plunge, where "trend" is analogous to dip direction and "plunge" is the dip angle. Strike and dip are measured using a compass and a clinometer. A compass is used to measure the feature's strike by holding the compass horizontally against the feature. A clinometer measures the features dip by recording the inclination perpendicular to the strike. These can be done separately, or together using a tool such a ...
