In FactoryTech one can use a River Grate to collect River Copper (or Nickel) Nuggets, which can be crafted into River Copper Ingots and then smelted in FactoryTech's own Electric Furnace into Copper/Nickel Ingots.

There's also a variety of metal dusts in the mod. I'm not sure if FactoryTech fully supports Oredict (a JEI search for $copper at least shows its Copper Ore block), but if it does, it would be nice if it could be integrated into UniDict.
