Underground hard rock mining refers to various underground mining techniques used to excavate hard minerals such as those containing metals like gold, copper, zinc, nickel and lead or gems such as diamonds. In contrast soft rock mining refers to excavation of softer minerals such as coal, or oil sands.
Copper mines are only set up where there is more than 5 kg of copper per tonne of rock 0.5 by mass. Ideally, the figure should be closer to 2. The worlds largest copper ore deposits are found in Chile on the west coast of South America.

The barren rock, or gangue has to be separated from the sulfide minerals in order to smelt the metallic copper from the ore. By far the greatest proportion of copper is extracted from the sulfides of copper, iron and sometimes other metals. Such ores originate from sulfur-bearing volcanic magmas, which have separated into metal sulfides and siliceous melts.
The open-pit mining is adapted for mining copper regarding which a series of stepped benches are dug deeper and deeper into the earth over time. The machinery is then used to drill holes into the hard rock, and explosives are inserted into the drill holes to blast and break the rock to remove the ore.

Dec 12, 2019 As hard rock mining developed, and locals were trained by German miners, Cornwall, England slowly emerged as a source of copper and tin. By the 1700s Cornish miners, called Cousin Jacks, had solved many of the earlier mining problems, and were considered some of the best at extracting ore. Their skills were in demand all over the world.

OREGON MINES. Mammoth Mine - Elkhorn Mnts. near Sumpter, OR. In the early 1850s, prospectors first discovered gold in the southern region of what was then Oregon Territory. In the 1860s, gold miners moved into eastern Oregon. In both areas, corporations with outside investors soon replaced small and independent mining operations.
Dry ore is the term often used. The second class of gold ores is auriferous copper ores. These are widely distributed throughout the United States and much of the chalcopyrite is gold bearing. These auriferous copper ores are especially abundant in Colorado, Utah, Montana and British Columbia.

Nov 04, 2019 An ore is a natural occurrence of rock or sediment which contains enough minerals with economically important elements, typically metals, that can be extracted from the deposit economically. The ores are extracted by mining for a profit from the earth they are then refined often by smelting in order to extract the valuable elements.

Sep 01, 2015 Gold along with copper, commonly occurs in porphyry deposits. Porphyry is generally defined as an igneous rock consisting of large-grained crystals such as feldspar or quartz dispersed in a fine-grained groundmass. Hydrothermal fluids containing sulphides associated with gold and copper are commonly deposited in cracks and faults in the porphyry.
