Most mineralogists include the requirements that a mineral have inorganic origin and internal crystalline structure. In accord with the latter requirement, an amorphous compound such as opal would be considered to be mineraloid.
Ground water dissolves these rock substances, and the dissolved minerals are present in tap water. Depending on the kinds of rocks the water comes in contact with, the minerals dissolved in the water may be just of a small amount of or they may be very concentrated.
