All minerals are water soluble. Macrominerals are those needed in > 100 mg quantities and microminerals in < 100 mg quantities. Let's look at the macrominerals first.

Minerals such as calcium, phosphorus, and magnesium are all important regarding their role in structural framework for bones and teeth. They also play important roles as dissolved ions in body fluids, acting as intermediaries in many physiological functions such as heart muscle contraction, maintaining acid-base balance and osmotic pressure, facilitating membrane transfer of essential compounds, and maintaining nerve irritability. Sodium, potassium, chloride, and sulfur are also macrominerals which play a variety of roles as ionic and salt forms in body fluids.

Now let's look at sources of macrominerals in the diet.
Microminerals are those minerals needed in less than 100 mg quantities. Trace minerals or trace elements are usually needed in microgram quantities. Microminerals include iron, zinc, copper, iodine, fluoride, chromium, cobalt, selenium, manganese, and molybdenum. The trace elements that are known to be essential nutrients are silicon, vanadium, boron, tin, and nickel. Arsenic, bromine, and lead have been suggested as essential trace elements but this is not confirmed.
