The safest way to extract gold from rocks at home is to crush the rocks. However, you might use mercury to extract the gold if you're able to obtain some, though this is dangerous.

This can be found in any hardware store, probably made of aluminum oxide, and possibly a 1/4 inch shank. Smaller ones for a Dremel tool will have a 1/8 inch shank, but I'd get the larger one.
