What makes something an insoluble impurity, is it anything to do with them not being ions?

Sometimes. It the solvent cannot ionize an impurity, then it may be considered an insoluble. But some impurities do not have to ionize to be soluble. Sugar, for example, dissolves in water but is not ionized. Each sugar molecule is surround by polar water molecules.
