High-purity calcium carbonate in freshwater clam shell |
|
| Authors: | Nelson D J Rains T C Norris J A |
| Abstract: | The calcium carbonate in freshwater clam shells is simlilar in purity to that designated reagent grade. A simple reprecipitation of the shell extract results in a product having less Sr and Mg than reagent grade CaCO(3). Clams are harvested commercially, and discarded shells are a high-quality raw material for the production of CaCO(3). |
