Ruthenium is refined with a form of ruthenium trichloride
Precious metal is rare and expensive. Recently its industrial importance has been recognized and its recycling by recovery is indispensable. We develop and distribute precious metal catalysts and compounds, and also carry out precious metal recovery from spent catalysts.
Spent catalysts containing precious metal are delivered from various industries.
1. Petrochemical, petroleum refinery
2. Pharmaceutical intermediates, incense, fine chemical
3. Treatment of emission gas, deodorization equipment
|Spent catalysts often include flammable compounds and moisture, and precious metals are often unevenly distributed in spent catalysts, which make sampling difficult. Therefore, pretreatment such as burning and crushing is necessary.
Sampling of analysis sample is an important process
to decide content of precious metal. We gather samples for customers, our own
and umpire assay at the same time.
We keep recovered precious metal and reprocess those when necessary to
- precious metal catalysts
- precious metal compounds
We name such method as Pool Account. We will report each customer deposit amount of such precious metal.
We can return recovered actual metal or purchase those
at the market prices.
