Charles Butters
Charles Butters (August 10, 1854November 27, 1933) was an American metallurgist, engineer and mine owner. A graduate of the University of California, he moved to Southern Africa in 1890 to construct a Newbery–Vautin chlorination process, chlorination plant for Hermann Eckstein & Company. Whilst there Butters pioneered the use of the gold cyanidation process for extracting the metal from low grade ore, which opened up new deposits in Witwatersrand. He also developed other methods that increased extraction efficiency. Butters left Eckstein in 1894 to jointly found a new firm, the Rand Central Ore Reduction Company. He joined the Johannesburg Reform Committee in 1895, a group of mostly immigrants to South Africa who demanded, among other things, a stable constitution, an independent judiciary, and a better educational system; he participated in the Jameson Raid, a botched attempt against the South African Republic, and was fined $2,000. Butters returned to the United States in 1898 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Vanning
Vanning is a type of ore dressing by which ores are washed on a shovel. Typically, a powdered sample of orestuff is swirled with water on the blade of a shovel and then given a series of upward flicking motions. The heavier ore is tossed up through the water and appears as a crescent shaped patch at the top of the charge with the lighter gangue below. Developed in western England, this process was still in use at a major tin mine and a mine waste collection firm in Cornwall until 1985. Frue Vanner In the 19th century the process was automated and used for the separation of ore on an industrial scale. The Frue vanner was one such machine that was widely adopted. It was invented in 1874, by W. B. Frue, Superintendent of the Silver Islet Mine, Ontario, Canada, who spent two years developing the system.E. Henry Davies, Machinery for Metalliferous Mines, London: C. Lockwood & Son 1894. p.320 (on Google Books) In the Frue vanner a continuous rubber belt 4 feet wide and 27½ feet long ...

People From Haverhill, Massachusetts
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of per ...
