Calcium carbide is a chemical compound that reacts with water to produce acetylene gas, which is combustible and is used in mining lamps. The gas also encourages fruit growth in plants such as pineapples. Calcium carbide is used in making steel, PVC, signal flares and some old-fashioned fireworks, in addition to mining.
Calcium carbide is man-made. It is produced in a 2000º electric arc furnace. There is no "natural source" for the substance. You cannot go dig it up somewhere. If you could, it would be a clear or bluish crystal, rather soft, with an unpleasant odor.
I would go into the science of it in more depth, but the foregoing answers the question asked and you don't need to be a chemistry major to understand it. :)

I'd be very surprised if miners still use acetylene lamps! They were used by miners in gas-free ground (usually metal-ore mines and underground stone quarries) many years ago. They were used by many cavers until electric lamps (usually ex-colliery) became common in the 1960s, then had a brief flurry of popularity again in the 1980s-90s when developments in caving techniques and equipment meant the electric mining lamps were no longer safe to use due to their liquid electrolytes . Now acetylene lamps are pretty well obsolete, displaced in mining and in caving by l.e.d lamps; and suppliers of calcium carbide are becoming hard to find.
What else can I help you with?
How does calcium carbide mixed with water help people?
Calcium carbide mixed with water produces acetylene gas, which can be used for welding, cutting, and producing light in carbide lamps. This gas is highly flammable and can be a useful source of energy in various industrial and mining applications.
How do you produce carbide?
Carbide is typically produced by reacting carbon with a metal, such as calcium or tungsten, at high temperatures. The process involves heating the metal and carbon source in an electric arc furnace until they chemically react to form carbide. The resulting carbide can be further processed and shaped into various products.
What rocks are a natural source of calcium carbonate?
Limestone, chalk, and marble are examples of rocks that are natural sources of calcium carbonate. These rocks are formed from the accumulation of calcium carbonate minerals over time, which can be used for various purposes including in construction, agriculture, and industry.
What is bonemeal used for?
Bonemeal is commonly used as a fertilizer to provide plants with a source of phosphorus and calcium. It can help improve root development, flowering, and overall plant growth. Additionally, it can be used as a natural pest deterrent in some gardening practices.
What does CaNO3?
CaNO3 is the chemical formula for calcium nitrate, which is a compound composed of calcium and nitrate ions. It is commonly used as a fertilizer due to its high solubility in water and as a source of calcium for plants.
What kind Of Carbide is needed for lamp?
Calcium Carbide is used in "Carbide Lamps". Water, added dropwise to Calcium Carbide yields acetylene plus calcium hydroxide. Acetylene is extremely flammable, giving a colorless flame. The calcium hydroxide present gives the flame its visibility. Calcium Carbide is used in "Carbide Lamps". Water, added dropwise to Calcium Carbide yields acetylene plus calcium hydroxide.

What is the "natural source" of the calcium in this prodct Often, calcium is recovered from oyster shells, but I have a shellfish allergy.?
In the product calcium is derived from calcium carbonate. Calcium carbonate is a natural source so if anyone of you is suffering from shellfish allergy, one may try this calcium carbonate.

What is the best source of calcium?
Citrus fruits are the best source of calcium.
Is cheddar cheese the poorest source of calcium?
No, it's a good source of calcium
Does milk have calcium in there?
Yes milk is a good source of calcium.
Why not take calcium hydroxide as source of calcium?
because after forming a compound calcium will not retain its properties
Is calcium in milk?
Yes. Milk is one of the main source of calcium.
How can you get more calcium?
Several food are a good source of Calcium, such as Milk, Yogurts, and just about any other dairy product. Certain vegetables are also a source of calcium; Carrots for example. But you could also start taking Calcium Supplements. They contain lots of calcium, and are good for people who don't enjoy milk, which is the primary source of calcium among the general public.
