So I've been junking and antiquing my whole life, but not scrapping. I understand when you arrive at most yards tey weigh you in to get a total weight. My uestion is, when taking multiple different types of metals to sell, do they weigh each group separately at each station and then total those types invidivually for you, or do you weigh in, drop off one type, and then weigh in again, and repeat for EACH type of metal? I hope that made sense.

I was just curious as to how they determine total weights between each metal when dumping them, as the videos I've seen seem to just show people weighing in at arrival, dumping their metal at each station in big groups, and then getting a total somehow.

I know this may sound like a silly question, but I'm curious before I start taking stuff to the yard and look totally unprepared.
