is calcium carbide mined or manufactured?

Question

calcium carbide reacts when wet. how can they prevent it from being wet if they are mined, or seepage from the ground?

Answer 1

Calcium Carbide is Manufactured.

calcium carbide reacts when wet. how can they prevent it from being wet if they are mined, or seepage from the ground? You are correct. But who says so?

Calcium carbide is produced in an electric arc furnace loaded with a mixture of lime and coke at about 2000 °C. Calcium carbide is formed:

CaO + 3C→CaC2 + CO.

Calcium carbide synthesis requires an extremely high temperature, ~2000 °C, which is not practically achievable by traditional combustion, so the reaction is performed in an electric arc furnace with graphite electrodes. This reaction was an important part of the industrial revolution in chemistry that occurred as a product of massive amounts of cheap hydro-electric power liberated from Niagara Falls before the turn of the 19th century.

Answer 2

Calcium carbide is produced in an electric arc furnace loaded with a mixture of lime and coke at about 2000 °C.

In order to satisfy weatherdude, I have provided the cite.

Nonetheless, attributions do not need to be given if the information therein can be reasonably expected to be found commonly in available scientific literature. The above information on calcium carbide is available in any number of books and publications. This is why the article itself does not bother with providing a cite.

Answer 3

It's manufactured see http://en.wikipedia.org/wiki/Calcium_carbide

EDIT: What a surprise, answer below is direct extract from Wikipedia with no attribution given.

Answer 4

CaC2 is not mined. It is manufactured using minerals that contain CaCO3.
