The Refining Process |
 |
Weigh Once received at a Morris and Watson office, refining is weighed in and assigned an individual job number ready to be processed in the refinery. Please note refining treatment charges are calculated using this received weight. |
 |
Melt When a job has been received at the refinery it is re-weighed before being melted into an individual bar homogenising the metal ready for analysis. |
 |
Analyse Each bar is tested using ISO certified assay procedures to assess the pure metal content contained. One, two and four metal assay testing is available depending on customer requirements. |
 |
Report When the final report has been generated customers are contacted to discuss results and outturn options. Morris and Watson can return refined metal as proceeds, bullion, granules, fabricated metal or a mix of these options. |
 |
Purify The bars are then dissolved and precipitated in a range of chemical solutions to remove base metals, and separate out each precious metal. Purified metals are then returned to customers or alloyed and fabricated into a range of products. |
