Brass is an alloy of copper and zinc, in proportions which can be varied to achieve varying mechanical, electrical, and chemical properties. It is a substitutional alloy: atoms of the two constituents may replace each other within the same crystal structure.. Brass is similar to bronze, another alloy containing copper that uses tin instead of zinc. Both bronze and brass also may include small ...
Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef, or placer deposit.These deposits form a mineralized commodity that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay.

The cyanide solution strength is also important in leaching gold, with the typical range of solution being in the 0.02% -0.05% NaCN. The gold particle size has a tremendous effect on the time required for dissolution in a cyanide solution. Generally, the finer the gold, the quicker it will dissolve. A 45 micron particle of gold would dissolve ...

The addition of non-corrosive metals during the making of steel imparts the anti-rust properties making it more resilient to use. Depending on how the steel bars are made you have the cold finished bars or hot finished bars. A lot of testing on several parameters is conducted before the bars are declared fit for use.
The largest copper mine in North America (and the world's largest man-made excavation) is the Bingham Canyon Mine near Salt Lake City, Utah. A $1.5 billion modernization program completed in 1998 turned Bingham Canyon into North America's lowest-cost copper producer, a model of operational efficiency and environmental compliance.

Meteorites contain both iron and nickel, and earlier ages used them as a superior form of iron. Because the metal did not rust, it was regarded by the natives of Peru as a kind of silver. A zinc-nickel alloy called pai-t'ung (white copper) was in use in China as long ago as 200 BC. Some even reached Europe.
In this astronomy science project, you will develop a rough scientific business plan for your very own asteroid mining company. However, mining asteroids is a dangerous and expensive venture, and it can take years for a spacecraft to reach an asteroid (the Hayabusa craft left Earth in September 2003, landed on an asteroid in November 2005, and did not return to Earth until June 2010!).

First you need to figure out how many moles of heavy metals you need. 8 millimoles equals 0.008 moles. This means that in 1000 mL of an 8 M heavy metal solution, there are 0.008 moles of heavy metals. Next figure out the molar mass of your heavy metal. This is often on its packaging, or you can look it up online.
