I wrongly assumed that the buyers I see on the internet and some that have responded here were refiners. I see now that they are not refiners but middlemen. <<
why would you assume a buyer was automatically a refiner. did you assume every scrap metal buyer or scrap yard was a smelter?
umicore, xstrata ( non u.s. facility) and hanawa are ewaste refiners. ecs, specialty metal, oh so accurate, envirochem, are all processors. if you are looking to write a book on the refined return rates of ewaste or the return rates averaged by processors, i would suggest you try them. i would think a good writer would have researched the subject and then gone straight to the source. there are several well known refiners and processors in the states. i am curious why you did not start there. tho i imagine they all told you it is confidential and proprietary information.
it is interesting how you have used innocence, guile, shame and guilt in the pursuit of an answer to your questions.
most of what you are seeking is available on the internet. the rest can be found in your larger library's. you simply have to know enough about the subject to know what to search for.
i can see another email in my future.
