Of course not!
Scientists have made tests which show that metal ions can leave buried metal particles and rise in the soil until they reach 10-30 cm below the surface. At this depth, they become bound with other elements in the soil to become compounds which are no longer ions. Then these metal compounds stay where they are, or are eroded away. (Or they may be excavated away by someone digging for a treasure).
