An ore is an occurrence of rock or sediment that contains sufficient minerals with economically important elements, typically metals, that can be economically extracted from the deposit. The ores are extracted from the earth through mining; they are then refined (often …
Most of the nickel we use on Earth is mined from a number of nickel ores: pentlandite and pyrrhotite (iron nickel sulfides, the two most important nickel ores), garnierite (hydrous nickel silicate), millerite (nickel sulfide), and niccolite (nickel arsenide).
The sulphide ores we mine contain more than just nickel. Other elements are often found and by extracting and processing nickel, our operations also produce cobalt, copper and precious metals. Other elements are often found and by extracting and processing nickel, our operations also produce cobalt, copper and precious metals.

Nickel was first discovered in Canada in 1883, and began being mined in the 1890s. So, it’s of little surprise that today the nation is one of the world’s five top nickel-producing countries.
Nickel mining occurs through extractive metallurgy, which is a material science that covers various types of ore, the washing process, concentration and separation, chemical processes and the extraction process. One of the most well-known purification processes is called the Mond Process, which is an extracting and purifying process developed by Ludwig Mond in 1899.
The mine has a mineral reserve of 124 million tonnes, with an average nickel content of 1.48% and a cobalt content of 0.11%. The mine began production in 2010 and has a …
Underground mining may take place following the evaluation of an ore body which can involve drilling for samples of ore over several years. Once a valuable ore deposit is located, the resource may be mined by sinking a shaft or by open pit excavation. To start a mine shaft, a ‘headframe’ is built to hold the equipment and machinery to access the ore and to move the ore and workers from the ...
What we mine & why we mine Minerals are central to our modern way of life. They are essential to producing materials for construction and manufacturing: steel and cement cannot be …
Interestingly, though, the Vermillion Mine also contained a high-grade nickel-copper ore body, platinum, silver, tin and other minerals proving to be a forerunner of future Sudbury area mines. Iron has also been mined in Sudbury until recent times, and along with the already mentioned precious metal ores and others, has been a by-product of the nickel-copper mineral processing.
Nickel was first isolated and classified as a chemical element in 1751 by Axel Fredrik Cronstedt, who initially mistook the ore for a copper mineral, in the cobalt mines of Los, Hälsingland, Sweden. The element's name comes from a mischievous sprite of German miner mythology, Nickel (similar to Old Nick ), who personified the fact that copper-nickel ores resisted refinement into copper.
10 Top Countries for Nickel Production Amanda Kay - April 5th, 2018 Indonesia, the Philippines, and Canada were the top countries for nickel production in 2017.
Nickel is extracted from ores via the Mond process, in which nickel oxides are purified through multiple steps into pure nickel metal. It is placed with hydrogen and carbon monoxide gases at 122 degrees Fahrenheit, which converts it to impure nickel.
Being free of sulfur, laterite nickel deposits do not cause a pollution problem as do the sulfide ores, but they do require substantial energy input, and their mining can have a detrimental effect on the environment (e.g., soil erosion). The range of process options is limited by the nature of the ore. Being oxides, laterites are not
Compared to tin mining, the history of zinc mining is relatively short. In the 18th century, it was discovered that sphalerite, or zinc sulfide, could be smelted into …
Nickel: An introduction - Explain that Stuff. Most of the nickel we use on Earth is mined from a number of nickel ores: pentlandite and pyrrhotite (iron nickel sulfides, the two most important nickel ores), garnierite (hydrous nickel silicate), millerite (nickel sulfide), and niccolite (nickel arsenide).
As the sulphides continue to sink we see net-textured (or matrix) ores which are the most common ore type in most high-grade nickel deposits. Here sulphides range from 5 to as much as 50+% of the rock, forming a matrix between silicate minerals. Depending on the dynamics of the magma chamber the sulphides can be thought to have sunk between and cemented together earlier formed silicate ...
What do Manitoba mines produce? Base and precious metals, such as nickel, copper, zinc and gold. Specialty metals like cesium. Industrial minerals such as dolomite, spodumene, silver, gypsum, salt, granite, limestone, lime, sand and gravel.

Nickel is one of the most important components to the U.S. stainless steel industry and as the steel industry continues to grow so too will the need for nickel. To meet this increasing need for nickel, it is critical that changes are made to the U.S. mine permitting process. Congress must reform the lengthy and duplicative permitting process in order to ensure manufacturers better access to ...
