How should I separate these items?

Thanks kss and JJin. That’s helpful info. As to the blocks in question. They’re cast iron inboard motor blocks. I have hundreds of aluminum outboard blocks but they’ll all be desleeved and sold as clean rather than breakage. KSS, you’re spot on with the comment about checking things for resale value rather than scrapping. This is all stuff that’s a byproduct of my reselling business. It’s either slightly damaged, something that isn’t commonly reused etc. I own a marine salvage business where we predominantly deal with outboard motors. We buy large quantities of them each year to part out as well as repair motors for customers etc. So it’s a multifaceted business with an online reselling presence, a brick and mortar retail shop with both new and used parts as well as a repair service. This generates a rather large amount of predominantly aluminum scrap. Thanks to both of you for your insights and advice. It’s much appreciated!!!
