west africa has long been considered a risky prospect where political instability volatile tax regimes and tricky relations with small-scale miners weigh heavily on boardrooms.
cupronickel or copper-nickel (cuni) is an alloy of copper that contains nickel and strengthening elements such as iron and manganese. the copper content typically varies from 60 to 90 percent. (monel metal is a nickel-copper alloy that contains a minimum of 52 percent nickel.) despite its high copper content cupronickel is silver in colour.

as an alloy material nickel gives other metals the hardness strength and corrosion resistance they need. nickel is now recognized as one of the most valuable mined materials in the 20th and 21st centuries making nickel mining an important industry. the basics of nickel mining and processing
copper and nickel are often used for construction and industrial purposes to produce various kinds of equipment and vehicles. about 45% of us copper is used in building construction. about 50% of us nickel is used for stainless steel products and 40% in alloys …
copper-nickel alloys have been around for 50 years and were originally used in offshore pipework. over time their application has been expanded to include parts in sea ships specifically in condenser/heat exchangers on ships and are used in desalination power plants and offshore fire water systems and for the sheathed splash zone protection of oil and gas platform legs.
a copper-nickel alloy of the 70-30 type having superior weldability. it is resistant to corrosion and biofouling in seawater has good fatigue strength and has relatively high thermal conductivity. used for seawater condensers condenser plates distiller tubes evaporator and heat exchanger tubes and saltwater piping. alloy k-500:
nickel was used industrially as an alloying metal almost 2000 years before it was isolated and recognized as a new element. as early as 200 bce the chinese made substantial amounts of a white alloy from zinc and a copper-nickel ore found in yunnan province. the alloy known as pai-t’ung was exported to the middle east and even to europe.
copper-nickel alloys lie midway in the galvanic series (see figure) and normal galvanic guidelines in seawater apply for these alloys. in some cases adding chlorine to the seawater may reduce or even prevent galvanic corrosion that may otherwise occur from more noble alloys in natural seawater e.g. with super stainless steels.
norilsk nickel is the world’s largest producer of nickel and palladium while competing with the top producers of platinum and copper. norilsk nickel's key russian production facilities include the polar division and the kola mining and metallurgical company.

oct 17 2019· a manganese silicate product attractive as feed for the manganese-alloy industry was also produced. the company is doing further test work and engineering that will lead to a pilot plant project next year to demonstrate the metallurgical flowsheet at scale to produce nickel & cobalt sulfate and copper cathode products with zero solid waste.
relation to mining. the united states had only one active nickel mine in 2013. there are also small amounts of by-product nickel recovered from copper and palladium-platinum ores in the western united states. more than 80000 tons of nickel is recovered annually by recycling stainless steel and other nickel-iron alloys.
nickel will alloy readily with many other metals including chromium iron molybdenum and copper. this allows for a wide variety of alloys that demonstrate outstanding resistance to corrosion and high-temperature scaling exceptional high-temperature strength and other unique properties such as shape memory and low coefficient of expansion.
