I would like to have a tutorial or a video on a guide to the scrap yard.I have NEVER driven across the scale with a load of scrap so I have questions that I want to ask because YES I am new and could be stupid because it seems so easy to do.I have watched videos of people going to the yard,going across the scales,shows the weight then they drive off to unload the metal.Next I see them driving back across the scale to get the difference in weight and then go and park and walk to go get their receipt and money so that causes me to ask the questions.Bare with me as I learn the process.

For a new guy this is all fun and new even though I hear the prices are low,I see it as free part time money regardless and it is sort of exciting finding goodies.Here are my questions.Thanks in advance

QUESTIONs

The receipt I have seen in videos shows the amount they are given for each type of metal..How did the yard know what (type of)metals they had when I seen the persons unloading it with no scrap employees around to know what type of metal was unloaded.

Do you take both your ferrous and non ferrous across the scale(seen a guy do this on YouTube)and unload the ferrous first and then unload the non? seems he was double dipping if that is so

What if I only have aluminum and bare bright,#1,#2 only..just go straight to the floor scale?
