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. The recycler will use a process like acid reduction or reverse electroplating to extract the gold from the nonmetal elements.
remember, the purity of 14k is 58.3%. actual pure gold content value of chain. So, we have a scrap gold chain that weighs 24.2 pennyweights. It is 14k so there is 58.3% pure gold in the chain. We took 24.2 pennyweights and multiplied it by .583% to get the weight of the pure gold. We come up with 14.1 pennyweights of pure gold. There are 20 pennyweights in one troy ounce. Spot gold is selling for $1349.00 per troy ounce. We divided $1349.00 by 20 to get a pure gold value of $67.45 per pennyweight.
