How do you assay metal scraps?
Our assay procedure (wet method) is not the same as the (dry method) other refineries use. Using the wet method, all the scraps are dissolved in acids, such as Hydrochloric acid and Nitric acid, then assayed and refined. It takes more time than the dry method.However, the wet method is more accurate than the dry method, because any samples from any point of dissolved metal shows the same assay results. On the other hand, the assaying by dry method is a little bit fluctuated and sometimes not as accurate.”
How long does it take to make a payment?
It usually takes 4 weeks to complete assaying, then we arrange payment by check or wire transfer.
What is your advantages compared to other refineries?
Asahi has over 200 years of refining experience. We use the latest assaying technolgy and our refining cost is less than others because we produce the final products such as gold and silver ingots and bars. Some refineries incinerate metal scraps and sell them to other refineries who produce the final products.
