• Underground mining (hard rock) Wikipedia

    Cut and fill mining is a method of short-hole mining used in steeply dipping or irregular ore zones, in particular where the hanging wall limits the use of long-hole methods. The ore is mined in horizontal or slightly inclined sls, and then filled with waste rock, sand or tailings.

  • Copper Mining and Processing: Everything you Need to Know

    The orious task of mining copper ore by hand made it difficult to obtain large quantities for production. During the Industrial Revolution, coal- and steam-powered machinery paved the way for a huge increase in copper production with mines smelting between 200 and 300 tons of copper ore per week.

  • A Brief Introduction to the Types of Surface Mining

    Thus, open-pit mining is ideal for ore deposits lying under thin rock, or ore deposits in the form of layers which can be easily removed by digging benches. The equipment used for this method is mostly restricted to dump or haul trucks, and shovels, though conveyors can quicken the process.

  • Hard Rock Mining Gold and Silver Ore and processing it

    In most gold ores, the final process to extract the tiniest gold particles is the use of cyanide to dissolve the gold. Cyanide, in the presence of oxygen actually dissolves both gold and silver. It is both efficient and inexpensive, so it is widely used in precious metal ore processing.
