most aluminum metal used in industry is an alloy where aluminum is combined with other elements such as copper zinc silicon and magnesium. applications for aluminum alloys include soda cans automobile parts bicycles aluminum foil power lines siding for houses and even baseball bats.
"gold recovery for dummies?" a discussion started in 2005 but continuing through 2019. 2005. q. well hello. i just stumbled across this forum as i was looking for information on gold scrap recovery and thought it was as good a place as any to start.
certain naturally occurring radioactive isotopes are unstable: their nucleus breaks apart undergoing nuclear decay. sometimes the product of that nuclear decay is unstable itself and undergoes nuclear decay too. for example when u238 one of the radioactive isotopes of uranium initially decays it produces th234 which decays to pa234.
she has taught high school ap chemistry for 2 years and is teaching undergraduate college chemistry for 3 years. this lesson will define solvent extraction and discuss and explain the process.
determine the strippingratiothe ratio of waste removed to ore recovered; it may range from as high as 45 yd /ton 38 m /tonne for coal mines to as low as 1.0 yd /ton 0.8 m /tonne in metal mines. some nonmetallic mines have no overburden to remove; the mineral is simply excavated at the surface.

the first mention of the systematic extraction of copper ore comes from about 3800 b.c. when an egyptian reference describes mining operations on the sinai peninsula. in about 3000 b.c. large deposits of copper ore were found on the island of cyprus in the mediterranean sea.
a. chemical extraction of precious metals from ore is a very long and tedious process. first the ore has to be roasted to a red hot temperature and held there for 2030 minutes; this reduces the sulfides to sulfur dioxide and the organic carbons to carbon dioxide.
