Why are nickel and copper often found together?

Nickel and Copper are often found together because nickel and copper have the same densities so when they are layered together between other minerals, they layer into one category


Where did the element nickel get its name from?

mid 18th century: shortening of German Kupfernickel, the copper-colored ore from which nickel was first obtained, from Kupfer 'copper' + Nickel 'demon' (with reference to the ore's failure to yield copper).


What chemicals are in a nickel?

The composition of the 5 cent nickel depends on the country, and the time it was manufactured. Generally, the nickel coins have less elemental nickel in them than other elements combined, due to health and economic reasons.

Where can you find cobalt in nature?

All cobalt that is processed for commercial purposes is obtained as a by-product of other metals. One major source is from copper. It has also been obtained from manganese nodules found on the floor of the ocean.


Why has phytomining been used to produce gold nickel and copper but is only rarely used to produce zinc and lead?

this question came up in the AQA chemistry text book and in some exam style questions. so the answer is: Phytomining is used to produce gold nickel and copper because they are found in low grade ores the main reason is that gold, nickel and copper are below carbon in the reactivity series which means they are found in native state. (sometimes copper can be found in low grade ores) but phytomining is used rarely to produce zinc and lead is because they are more reactive than gold nickel and copper. this is why phytomining been used to produce gold nickel and copper but is only rarely used to produce zinc and lead.
