You can mine for calcium pretty much anywhere on Earth. You can find calcium in sedimentary, igneous and metamorphic rocks. Many minerals contain calcium, some of them being limestone, marble and dolomite.

The reason why you can mine for calcium everywhere is due to calcium being the fifth most abundant material on Earth's crust, although only representing 4% of it.

Now, keep in mind that you will never find calcium in its elemental form as it is reactive with water and oxygen. After mining it, you will need to purify it, possibly with electrolysis. Through the purifying processes, you can obtain a purity close to 99%.

Examples of mines extracting calcium are the Lengefeld Lime Works and a limestone mine located on Guarello Island. These mines are extracting calcium carbonate, which is the most common form of calcium you will find. It has many practical uses, like being the material used to create chalk.
