Tubal Cain Mine
Tubal Cain Mine is an abandoned copper mine in the Buckhorn Wilderness, east of Olympic National Park in the US state of Washington. The main adit penetrates 450 meters into Mount Worthington. The mine is named after Tubal-Cain, a character mentioned in the Bible. The Book of Genesis 4:22 says that Tubal-cain was a "forger of all instruments of bronze and iron," a metalsmith. History In 1902, copper was discovered in the Dungeness River drainage. The ore was said to have both copper and gold. Later that year, the Tubal-Cain Copper & Manganese Mining Co. headquartered in Seattle built a trail and began to mine ore out of the area. After an avalanche in 1912, which destroyed the main sawmill, powderhouse, and barn and clubhouse, activity at the mine declined. The mine never produced a dime of profit. Most geologists believe upheaval of the Olympic Mountains broke and scattered any large veins or pods of ore that may have existed.Taylor, Eva Cook. The Lure of Tubal Cain Mine. J ...

Metalsmith
A metalsmith or simply smith is a craftsperson fashioning useful items (for example, tools, kitchenware, tableware, jewelry, armor and weapons) out of various metals. Smithing is one of the oldest list of metalworking occupations, metalworking occupations. Shaping metal with a hammer (forging) is the archetypical component of smithing. Often the hammering is done while the metal is hot, having been heated in a forge. Smithing can also involve the other aspects of metalworking, such as refining metals from their ores (traditionally done by smelting), casting it into shapes (foundry, founding), and file (tool), filing to shape and size. The prevalence of metalworking in the culture of recent centuries has led ''Smith (surname), Smith'' and its equivalents in various languages to be a common surname#Occupational name, occupational surname (German Schmidt (surname), Schmidt or Schmied, Portuguese Ferreiro, Ferreira (surname), Ferreira, French Lefèvre, Spanish Herrero, Italian Fabbr ...

Copper Mines In The United States
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 bronze, c. ...

Pelton Wheel
The Pelton wheel or Pelton Turbine is an impulse-type water turbine invented by American inventor Lester Allan Pelton in the 1870s. The Pelton wheel extracts energy from the impulse of moving water, as opposed to water's dead weight like the traditional overshot water wheel. Many earlier variations of impulse turbines existed, but they were less efficient than Pelton's design. Water leaving those wheels typically still had high speed, carrying away much of the dynamic energy brought to the wheels. Pelton's paddle geometry was designed so that when the rim ran at half the speed of the water jet, the water left the wheel with very little speed; thus his design extracted almost all of the water's impulse energywhich made for a very efficient turbine. History file:Pelton wheel (patent).png, Figure from Lester Allan Pelton's original October 1880 patent Lester Allan Pelton was born in Vermillion, Ohio in 1829.

Boilers
A boiler is a closed vessel in which fluid (generally water) is heated. The fluid does not necessarily boil. The heated or vaporized fluid exits the boiler for use in various processes or heating applications, including water heating, central heating, boiler-based power generation, cooking, and sanitation. Heat sources In a fossil fuel power plant using a steam cycle for power generation, the primary heat source will be combustion of coal, oil, or natural gas. In some cases byproduct fuel such as the carbon monoxide rich offgasses of a coke battery can be burned to heat a boiler; biofuels such as bagasse, where economically available, can also be used. In a nuclear power plant, boilers called steam generators are heated by the heat produced by nuclear fission. Where a large volume of hot gas is available from some process, a heat recovery steam generator or recovery boiler can use the heat to produce steam, with little or no extra fuel consumed; such a configuration is common ...

Dungeness River
The Dungeness River is a long river located in the Olympic Peninsula in the U.S. state of Washington. It rises near Mount Constance in the Olympic Mountains within the Olympic National Park, flows through the Buckhorn Wilderness, passes by the town of Sequim, and empties into the Strait of Juan de Fuca at Dungeness Bay, behind the Dungeness Spit. One of its main tributaries is the Gray Wolf River. It is crossed by the Dungeness River Bridge. The river was named for Dungeness Spit. The name "Dungeness" refers to the Dungeness headland in England. It was given by George Vancouver in 1792, who wrote: ''The low sandy point of land, which from its great resemblance to Dungeness in the British Channel, I called New Dungeness.'' Scarborough Island is a small eyot (river island) in the Dungeness River, in Sequim, Washington. About one acre square, it is located near Dungeness Meadows and can be seen from the Dungeness River Dike. See also *List of Washington rivers *Dungeness crab ...

Book Of Genesis
The Book of Genesis (from Greek ; Hebrew: בְּרֵאשִׁית ''Bəreʾšīt'', "In hebeginning") is the first book of the Hebrew Bible and the Christian Old Testament. Its Hebrew name is the same as its first word, ( "In the beginning"). Genesis is an account of the creation of the world, the early history of humanity, and of Israel's ancestors and the origins of the Jewish people. Tradition credits Moses as the author of Genesis, as well as the books of Exodus, Leviticus, Numbers and most of Deuteronomy; however, modern scholars, especially from the 19th century onward, place the books' authorship in the 6th and 5th centuries BC, hundreds of years after Moses is supposed to have lived.Davies (1998), p. 37 Based on scientific interpretation of archaeological, genetic, and linguistic evidence, most scholars consider Genesis to be primarily mythological rather than historical. It is divisible into two parts, the primeval history (chapters 1–11) and the ancestr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Copper Mine
Copper extraction refers to the methods used to obtain copper from its ores. The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors. As in all mining operations, the ore must usually be beneficiated (concentrated). The processing techniques depend on the nature of the ore. If the ore is primarily sulfide copper minerals (such as chalcopyrite), the ore is crushed and ground to liberate the valuable minerals from the waste ('gangue') minerals. It is then concentrated using mineral flotation. The concentrate is typically sold to distant smelters, although some large mines have smelters located nearby. Such colocation of mines and smelters was more typical in the 19th and early 20th centuries, when smaller smelters could be economic. The sulfide concentrates are typically smelted in such furnaces as the Outokumpu or Inco f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bible
The Bible (from Koine Greek , , 'the books') is a collection of religious texts or scriptures that are held to be sacred in Christianity, Judaism, Samaritanism, and many other religions. The Bible is an anthologya compilation of texts of a variety of forms originally written in Hebrew, Aramaic, and Koine Greek. These texts include instructions, stories, poetry, and prophecies, among other genres. The collection of materials that are accepted as part of the Bible by a particular religious tradition or community is called a biblical canon. Believers in the Bible generally consider it to be a product of divine inspiration, but the way they understand what that means and interpret the text can vary. The religious texts were compiled by different religious communities into various official collections. The earliest contained the first five books of the Bible. It is called the Torah in Hebrew and the Pentateuch (meaning ''five books'') in Greek; the second oldest part was a coll ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tubal-Cain
Tubal-cain or Tubalcain ( he, תּוּבַל קַיִן – ''Tūḇal Qayīn'') is a person mentioned in the Bible, in , known for being the first blacksmith. He is stated as the "forger of all instruments of bronze and iron". A descendant of Cain, he was the son of Lamech and Zillah. Tubal-cain was the brother of Naamah and half-brother of Jabal and Jubal. The Israeli kibbutz Tuval is named after him. Jewish narrative According to Rashi, Tubal-cain's name literally means "Cain's-Spices", with the Hebrew word Tū́ḇal () deriving from the word Tū́ḇlin () meaning spices. Rashi states that he was named this, because he "seasoned and improved the work of Cain". In other words, because he was a blacksmith, who helped to make weapons which could be used to kill more efficiently, he invokes his ancestor Cain's sin of murder. Furthermore according to Tanhuma bar Abba, one day, Tubal-cain and his father, Lamech, were hunting together with Tubal-cain serving as an aid for hi ...
