Silver Mining Process. The process of mining for silver is broken down into three steps: removing ore from the earth, breaking it down and then flushing the silver from ore. The first step involves drilling holes in the silverrich areas geologists have previously pinpointed and then inserting dynamite sticks.

What is Molybdenum. Molybdenum (element #42, symbol Mo) is a metallic, leadgray element, with a high melting point (4,730 degrees Fahrenheit). This is 2,000 degrees higher than the melting point of steel, and 1,000 degrees higher than the melting temperature of most rocks. Molybdenum was discovered by Carl Wilhelm Scheele in 1778, and was ...

This work examines alluvial gold deposit mining and processing methods from the Argonautic expedition until the Renaissance. According to Greek mythology, the mountain rivers of Colchis (Georgia) carried coarse sand and gold particles, which were washed in special wooden sluice boxes. The finer fractions were held in the lower part of the device, which was lined with sheepskin.

Salt/Halite Mining Process. Salt is generally produced one of three ways: deepshaft mining, solution mining or solar evaporation. Deepshaft mining is much like mining for any other mineral. Typically, the salt exists as deposits in ancient underground seabeds, which became buried through tectonic changes over thousands of years.

What is Pyrite. Commonly called fool's gold, pyrite is the Earth's most abundant sulfide mineral. Recognized for its brassyellow color which resembles that of gold, pyrite is a source of iron and sulfur and is used for the production of sulfuric acid. Some types of pyrite contain enough microscopic gold to warrant mining them as a gold ore.

to acceptable rates of gold recovery at the sluices, and when sands with the presence of fine and fine gold are mined, losses increase even more. To reduce the loss of gold on the devices of the Derokertype, a scheme was tested with the division of the flow of deep filling sluices (DFS) into two flows: oversize and undersize (Fig. 1).

What is Graphite. Pure graphite is a mineral form of the element carbon (element #6, symbol C). It forms as veins and disseminations in metamorphic rocks as the result of the metamorphism of organic material included in limestone deposits. It is an extremely soft mineral and it breaks into minute, flexible flakes that easily slide over one another.
