How to obtain Calcium Carbonatecalcium carbonate?

I read itcalcium carbonate is the main component of seashells and other animalsanimals' shells such(such as snails), and also limestone. How can I prepare pure $CaCO_3$$\ce{CaCO_3}$?

Could someone describe the process and the chemical equations involved? I saw this video: https://www.youtube.com/watch?v=rKqbMEy30XM

this video and apparently that's one way. Are there others? For example, is there a way to obtain Calciumcalcium carbonate from bones?

Do Please do tell me about the risks, but don't worry about my safety, since this is not going to be done in real life, but in a Minecraft mod instead. It is important to know the risks though, because I would like to make those risks part of the game, to make veryvery clear for my players that, if its risky, the same stuff that happens to Steve/Alex will happen to them. (I intend to make it realistic gruesome, meaning I won't exagerate a bit, but either will I minimize the risks because it's "just"just a game"game". I'm 14, so I know better, but I know Minecraft is played for kids as young as 7, so I really don't wan't little toddlers thinking Chemistry is all fun and games).
