Kosaka Smelting & Refining produces nearly 20 different kinds of valuable metals such as gold, silver, copper, lead and so on. On a global scale, such a wide variety of products is quite rare.
Meanwhile, Kosaka Smelting & Refining is one of only four smelters in the world which can treat complex sulfide ore and has the capability to produce both copper and lead at a single plant.
Before the spread of COVID-19, we provided a facility tour at Kosaka Smelting & Refining, so that customers can check the traceability by themselves. After COVID-19 is over, you are more than welcome to visit our smelter!
DOWA's assay reports are much more stable than others.
When treating high grade printed circuit boards, even a slight deviation in the analysis results can make a big difference. If I can’t estimate selling and buying price accurately, I don’t feel confident to buy and sell E-scraps.
I trust Dowa because of its stability of assay results with our estimation. Also, their response to our inquiry is always quick and appropriate. That is why we sell our high grade printed circuit boards to DOWA.
Some smelters’ terms are good, but they sometimes treat us bad with late response or don't answer questions at all. DOWA looks into our questions and always proposes most suitable solution with positive attitude. Their after-care-service is great.
We deal with DOWA's sales reps directly. They timely provide information that we need with transparency. On the other hand, it takes time to get information through an intermediate trader. DOWA also has a high degree of traceability, so we will go with DOWA as a long term business partner.
