First you mix both chalk and salt in water. From the solution that you get, you can filter the chalk out because it is non soluble in water. As for the salt, all there is to do is to just evaporate the water out.
You can easily separate salt and marble chips by adding water to the chips. The salt will dissolve in the water while the marble will remain solid.
Marble is primarily made of calcium carbonate. Vinegar has acid in it. When the weak acid contacts the calcium carbonate, it gives off bubbles of carbon dioxide gas, and eventually will erode the surface of the marble chips.
If we're talking about normal rice-sized rice and standard glass marbles, it's not much of a problem; it would be like separating horses from cats. So let's suppose the "marbles" are chips of metamorphic limestone, cunningly carved to resemble grains of rice. 1. Since rice is less dense that marble, we could irrigate (flush with water) the rice-marble mixture. At some velocity, the rice would be washed away while the marble would remain. 2. We could just a stream of air the same way. 3. We could expose the mixture to a colony of ants, who would carry away the rice and leave the marble.
We own a Gun range and had this exact same problem. we ended up shoveling the wood chips full of lead pellets into buckets of water, skimming off the wood chips and recovering the lead that way.
Boiling off the water from a salt solution will separate the solid salt and water (which can be collected by a condenser).
Hold a magnet over it and the iron will fly out of the salt and stick to it, and the salt will stay there.
Marble. Dried peas. And salt
pH is measured only in solutions or liquids. Marble chips has not a pH.

it depends on amounts of marble and concentration of acid
Calcium Carbonate
No the water would drain around the chips. They would not absorb water.
calcium carbonate :)
Marble chips are calcium carbonate. If the hydrochloric acid is strong(concentrated), it acts upon the marble and corrodes it liberating
No, you cannot grind marble chips using a pestle and mortar. This tool is typically used for more kitchen applications then home repair.

What brand? No two will be alike. Chips in general are very high in salt though. check the bag.
