Resolution Copper Mine — No. 9 Shaft Deepening Project

The most viable way to recover the resource is by going deep underground, and to do so, Resolution is using the block caving process—one of the most economical underground mining methods available for this type of large, deep deposit. Originally constructed in 1971, the No. 9 mine shaft

Shaft sinking - Wikipedia

Shaft mining or shaft sinking is excavating a vertical or near-vertical tunnel from the top down, where there is initially no access to the bottom. Shallow shafts, typically sunk for civil engineering projects, differ greatly in execution method from deep shafts, typically sunk for mining projects.

Innovations: Introduction to Copper: Mining Extraction

Copper minerals and ores are found in both igneous and sedimentary rocks. Mining of copper ores is carried out using one of two methods. Underground mining is achieved by sinking shafts to the appropriate levels and then driving horizontal tunnels, called adits, to reach the ore.

Copper Mining and Processing: Everything you Need to Know

The Basics of Copper Mining and Processing Mined from open pits, copper ore must be crushed as part of the process that occurs between extraction and production. Using today’s compact mining equipment, copper ore is extracted from the mine. After the ore is crushed, it’s roasted, which helps to convert sulfides to oxides.

How Underground Mining Works HowStuffWorks

The least common method in hard-rock mining, block caving, is typically saved for low-grade ore. It involves drilling a section of ore at the very bottom of the deposit and then blasting to make the roof collapse. Gravity then takes over, as the ore above the blast site fractures and collapses in succession as support is withdrawn.

deep shaft mining how was it solved 1850

The Basin's mines are the only deep shaft copper mines east of the Mississippi River. Copper mining also occurred in Michigan but the ore there was close to the surface and could be extracted by strip mining. The Copper Basin's ore was located in three deep seams and could only be extracted by deep shaft mining. Deep shaft mining . Poppet Head, Waiuta Goldmine - Shaft 1300 feet deep ...

Mining - Underground mining Britannica

Mining - Mining - Underground mining: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of material mined, are much

ICMM Where and how does mining take place?

Strip mining – the targeted removal of surface layers to reveal the useful ore/seams underneath. By contrast, sub-surface mining consists of digging tunnels or shafts into the ground to reach deeply buried ore deposits. Some mining, including rare earth elements and uranium extraction, is done using less common methods, such as in-situ ...

Deep sea mining - Wikipedia

Deep sea mining is a mineral retrieval process that takes place on the ocean floor.Ocean mining sites are usually around large areas of polymetallic nodules or active and extinct hydrothermal vents at 1,400 to 3,700 metres (4,600 to 12,100 ft) below the ocean’s surface. The vents create globular or massive sulfide deposits, which contain valuable metals such as silver, gold, copper ...

Modern copper smelters use processed copper ore fed into a flash furnace, typically fired by oxygen which produces blister copper, being further processed in a converter furnace. Molten copper is poured from here into rectangular moulds, the resulting ingots subjected to electrolysis producing a metal of 99.9% purity. Copper can be recycled indefinitely without the base metal
