Man knew more about gold itself and lusted for it much before he understood the geology of hard rock gold or its deposits. Man had to learn about hard rock extraction methods and how to locate those gold deposits just to satisfy the thirst for that yellow metal. Gold has been the most highly esteemed and sought after precious commodity since the times of antiquity It has spurred on numerous
Porphyry copper deposits commonly contain hundreds of millions of metric tons of ore that averages a fraction of 1 percent copper by weight; although they are lowgrade, the deposits constitute important sources because they may be worked on a large scale at low cost.
Copper mines are only set up where there is more than 5 kg of copper per tonne of rock (% by mass). Ideally, the figure should be closer to 2%. Ideally, the figure should be closer to 2%. The world''s largest copper ore deposits are found in Chile on the west coast of South America.
· Sulfide Ores . Virtually all sulfidetype copper ores, including chalcocite (Cu 2 S), chalcopyrite (CuFeS 2) and covellite (CuS), are treated by crushing the ore to a fine powder, it is concentrated by froth flotation, which requires mixing the powdered ore with reagents that combine with the copper to make it hydrophobic.
· Melt down copper ore via heating in the Processing window. 5 ore = 1+ shards, 10 shards = 1+ ingots. level 1. 2 points · 4 years ago. You will need to own a Mineral Workbench. Melt down the copper ore through the processing tab, then via the workbench and a worker, turn the melted copper goo into ingots. level 2 . 3 points · 4 years ago. You can also make the ingots yourself. You need to
copper ore is found just about everywhere. its hard not to find it! Comment by Best place to farm: HORDE Durotar (for all levels): Just start from Orgrimmar and do a lap around the map counterclockwise. I do it in 20 minutes with a 60% mount and get about 110 ores a run. Very fast respawn rate so you can do many runs in a row. Remember to go into the cave north of Razor Hill just
A copper rock is a rock that contains copper ore. It can be mined with a Mining level of 1. It is one of the first rocks that can be mined, along with tin rocks. Each time a player successfully mines a copper rock they gain Mining experience. Mining 14 tin ore and 14 copper ore (wielding the pickaxe as a weapon to free the 28th inventory space) and smelting them to bronze bars is a slow
Copper porphyry deposits are by far the most common copper ore type, however they tend to be of relatively low grade. The enormous Chuquicamata porphyry copper deposit in Chile is the largest open pit copper mine in the world by volume of rock excavated. Blue coloured copper carbonate staining on a rock surface. Inset: azurite, a copper

· Copper ore rocks contains copper ore. It can be mined with a Mining level 1. It is one of the first rocks that can be mined, along with tin ore rocks. Copper ore, being one of the easiest to mine, is scattered all around RuneScape.
The average grade of copper ores in the 21st century is below % copper, with a proportion of economic ore minerals (including copper) being less than 2% of the total volume of the ore rock. A key objective in the metallurgical treatment of any ore is the separation of
Copper ores. An ore is a rock containing enough valuable mineral to make it worth extracting. In the case of copper, it is worth extracting when there is about 2 kg of copper per 1,000 kg of ore (%). Copper minerals are found in over one hundred varieties, although only a few have been worked for copper on a large scale. The most abundant ores are chalcopyrite and bornite, which contain
The ore hopper at the front is not part of the of the most important aspects of underground hard rock mining is ventilation. Ventilation is required to clear toxic fumes from blasting and removing exhaust fumes from diesel equipment. In deep hot mines ventilation is also required for cooling the workplace for miners. Ventilation raises are excavated to provide ventilation for
The mines that produce our gold, silver, copper, and uranium are notorious for polluting adjacent streams, lakes, and groundwater with toxic byproducts. The Environmental Protection Agency estimates that 40 percent of the watersheds in the western United States are contaminated by pollution from hard rock mines.

''Acid rock drainage occurs naturally within some environments as part of the rock weathering process but is exacerbated by largescale earth disturbances characteristic of mining and other large construction activities, usually within rocks containing an abundance of sulfide minerals. The most commonly mined ore of copper, chalcopyrite, is itself a copperironsulfide and occurs with a range
Underground mining (hard rock) 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.
