Many forts are grievously short of useful metals; fortunately, good site location can ensure ample veins of goblinite. The mining process generally proceeds in two phases: slaughter the carriers, then collect, sort, and smelt the goblinite. I am looking for ways to streamline the latter process.
My best solution, in previous forts, was an obsidian casting/welcoming chamber. Incoming goblinite carriers would trigger pressure plates, dumping their companions into the welcoming chamber, then be killed or caged by traps. This solves the "mope around near the squad leader" problem that can otherwise result in carriers parking themselves near your first trap, requiring goblinite miners to go carry out the slaughter personally. Once all carriers had been slaughtered or placed in the welcoming chamber, I would close the bridges, flood the magma and water floors, dump them, and cast the goblinite in obsidian. This had the advantage of destroying the unwanted clothing and gewgaws and leaving only the iron items. I could mine out the obsidian, melt the iron, and have a clean collection process, with only the stray goblinite that never made it to the chamber to deal with piecemeal. Unfortunately, in my current fort, the goblinite consists only of copper, which I believe will be destroyed by the obsidianising process. (Also I'm tired of building hundred-z-level pump stacks.) So obsidian casting is out.
The other problem is the degree to which dwarves are (now) appalled to see dead goblins. When a rich vein of goblinite arrives and is slaughtered, by architecture or by goblinite miners, the bodies need to be disposed of. Obsidian had the advantage of obliterating the bodies, but I want the copper, so that's out. My best bet so far is to have a specialized cadre of corpse-disposers who are the only ones allowed into the kill zone until all the bodies are dumped. Then ordinary haulers can collect the goblinite. Nevertheless my corpse-disposers have page after page of "horrified to see a goblin die" in their thoughts, and the stress persists for years. It's also not a lot of fun sorting through my dwarves trying to guess which ones won't crack under the strain of body disposal.
How do you deal with goblinite collection?
