Calcium carbonate and magnesium carbonate

Do you mind me asking what the purpose of this experiment is?

These are undoubtedly in aqueous solution so simple evaporation should achieve what you want. However, separating the two would be more challenging.
You need to check the other ingredients though as there may be other components which will be
(a) dangerous when dry
and
(b) toxic in their vapour form.

If we dont have any other compounds in mixture just putting those 2 in water and bubling some CO
2
will create Ca(HCO
3
)
2
which is soluble..could this work? Or will MgCO
3
react in same way..?

This makes a big difference. You have a lot of sugars present. You would need to heat the dried material to carbonise it (messy) or oxidise it, extract with deionised water, filter and dry again.

@nousername
I am assuming that you are not taking a chemistry course at this time and not very experienced in chemistry and you are pondering this as a citizen scientist. So I moved your post to this board.
If you have the product name, you can use the MSDS (material safety data sheet) to give you an idea as to all of the likely components as well as purity.

@Archer
I am thinking that since Calcium carbonate and magnesium carbonate are not very soluble that they are using the molasses to assist in getting more into solution.
Or should I really say allow the Calcium carbonate and magnesium carbonate particles to suspend in water.
Or is my slip showing?

You are quite right, would need a lot of water! (my bad).
Probably would need to use HCl to get them into solution.
Convert to hydroxide then bubble CO
2
through to make carbonate.
Just buy the stuff, it would be simpler
