What the Expert Says:

I'd guess they would all be about the same since they are all sodium chloride, NaCl, except for Epsom salt which is magnesium chloride.

As I researched about your question I found out that - Table Salt is faster, because it's much finer, therefore it melts the ice faster, however, Rock salt is mostly preferred for de-icing because it has particles as large as 5mm. It also depends on the temperature, temperature makes a huge difference, at what temp the project going on.
