what machines are used during mining for silver
Underground Mining. Underground Mining is generally used for areas where the mineral seam is too far underground for open cut mining to be of use. A tunnel, called a decline, is created to allow workers and machinery to reach the location of the minerals. Stope mining is used for most hard rock mining of minerals such as copper, silver, lead ...

Aug 21, 2013· Minera Esperanza’s copper and gold mining operation, located 180km from the city of Antofagasta in Chile, is one of the driest places in the world. The mine needs approximately 20m cubic metres of water a year to run. To meet these demands the mine’s processing plant was designed to use untreated seawater.
For example, using surface mining techniques, many mining operations are now able to extract over 85 percent of minerals and 98 percent of metallic ores — without digging a shaft or endangering the lives of workers. Newly-developed machines used for grinding and crushing can extract minerals from the earth with less energy than ever before.
Stamps were used in California gold mines around 1850. First developed in England and used by Cornish miners, stamps were heavy iron machines used to pound rocks containing gold quartz into a fine dust so the gold ore could be extracted. Small stamps were commonly powered by water wheels while larger ones ran by steam engines.
Gold prospectors use tools such as gold pans, sluice boxes, drywashers or highbankers to find gold. Modern prospectors may use metal detectors to help locate likely spots, while commercial mining operations use trommels to help crush rocks and separate gold.
GOLD AND SILVER A. Commodity Summary Gold and silver are discussed together in this report since most of the processes used to recover one will also recover the other. In addition, both metals are often found together in nature. A particular mine is generally classified as
A desktop or custom-built computer designed for mining. You may use your current computer to start, but you won't be able to use the computer while the miner is running. A separate dedicated computer is ideal. Do not use a laptop, gaming console or handheld device to mine. These devices just are not effective enough to generate income.
Silver mining in the United States began on a major scale with the discovery of the Comstock Lode in Nevada in 1858. The industry suffered greatly from the demonetization of silver in 1873 by the Coinage Act of 1873, known pejoratively as the "Crime of 73", but silver mining continues today.. United States mines produced 1,170 tons of silver in 2014, 17% of the silver it used. 63% of ...

By 1860, gravel that would pay to work by these methods was now hard to find and gold production declined. Seeking increased mining efficiency the use of water in motion was further exploited. Ground sluicing used a stream of water which was brought to the top of a bank of gravel and allowed to flow down over the face.
The early attention paid to mining focused on gold and silver discoveries. However, later, discoveries of industrial minerals like coal, copper, iron, oil, and gas, stimulated new and continued growth of settlements in the west.

Stibnite is also the mineral name for antimony ore. Mining for gold and antimony began at Stibnite in 1931. Later a body of rich tungsten ore was found. During World War 11, Stibnite produced ninety-eight percent of America's antimony, and much of her tungsten. Both metals were vital for making machines and weapons for fighting the war.
There are four main mining methods: underground, open surface (pit), placer, and in-situ mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments. In-situ mining ...
