The gold found in pulled or discarded fillings, bridges and casting molds can be collected by dentists and sent to a recycler. The purity of dental gold is usually 16 karat, but it is slightly more complicated to recycle than jewelry because it may include nonmetal content like tooth enamel or porcelain.
Thereâs also an isotope of mercury, mercury 196, that can be turned into gold (itâs above and two to the left from gold 197).Lead, on the other hand, is in a bad position to form gold. Using neutron bombardment you can move to the right on the chart, but if you follow the decay path from every heavy isotope of lead, they all lead back to either lead or bismuth.
