I'm curious,

I just collect a little scrap from time to time. Power Cords, Fittings, nozzles ect.



Does anyone know how the weight is measured, and classified if I wanted to just bring a bucket in of dirty copper fittings
and Brass together ? (Brass Pull Knobs, Hinges ect.)


If I have say 3 lbs of materials, I'm not interested in separating everything.
