The Copper Basin - ... It was shipped north of the Revere Smelting Works near Boston.” (Barclay) The haulers would load copper and return with merchandise and mining supplies from the stores, taking four days of travel. In 1857, there were five regularly operating mines, eventually consolidating into three larger companies in 1858. The largest was the Union Consolidated which controlled 2575 acres of mining lands. When the Civil War summoned miners to fight in armies, most mines closed down. These mines were owned by northern industrialists, but by 1863 southern capitalists won over....   [tags: copper mining, southeatern tennessee] 1631 words

Analysis of Copper - ... The absorbance recorded for the sample being tested can be matched with a concentration using the graph generated by the standards. Ultraviolet-Visible Spectroscopy Spectroscopy involves the measurement of light absorbed or emitted from a sample. In ultraviolet-visible spectroscopy (UV-Vis), light in the ultraviolet-visible region has the same energy as energy levels for some of the electrons in molecules, so absorption of this radiation will excite electrons in a molecule to higher energy orbitals....   [tags: efficacy, accuracy, minerals, copper]

An Investigation into Electrolysis - Copper Sulphate - An Investigation into Electrolysis - Copper Sulphate Introduction Decomposition caused by electricity is called electrolysis. The electrical energy causes a chemical change. When a salt is dissolved in water, its ions become free to move so the solution can be "electrolyzed." The products of the electrolysis depend on the chemical solution, its strength and the type of electrode. The cathode is negatively charged and therefore attracts to it positive ions. E.g. hydrogen. The more reactive substance stays in the solution whereas the less reactive is released and appears as a gas (hydrogen) or a coating of metal....   [tags: Papers] 1372 words
