Very good company. I toured their plant some years ago. Amazingly
clean when you consider what they actually have to do. Their
metallurgical lab is top notch and very helpful if you have casting
or other metal related questions or need an assay or testing. I
highly recommend their casting alloys S88 for de-ox silver, 915 for
white gold and 450 for 14K yellow.
They pay well and give a good exchange if you take metal for
settlement. Turn around time seems a little slow, but for sweeps and
contaminated scrap they have to process first. Clean scrap might be
quicker, but it has been a long time since I sent any. I have tried
some of the quick turn around refiners for clean scrap. They pay for
gold only. United will include silver in the settlement even if it
is only a few cents.
