Dissolved Mineral Salts. 1  The principal ions found in water are calcium, magnesium, sodium, bicarbonate, sulfate, chloride and nitrate. A few parts per million of iron or manganese may sometimes be present and there may be traces of potassium salts, whose behavior is very similar to that of sodium salts.
Liquid Minerals. A solid mineral deposit can also be formed from the evaporation of a liquid solution. When a mineral is suspended in a solution, it can collect as the water in the solution evaporates into the air.inerals grouped together form rocks; the combination of minerals determines the type of rock formed. Since minerals are pure, they can all be written as a single chemical formula. A mineral can also contain some impurities and still retain its name, as long as the majority of the solid is a single mineral.
