Its just like being a steel mill and trying to buy everything for as cheap as possible and trying to get maximum return out of your melt. Every mill has a different way of melting there steel, different buying program, different alloys produced, different mixing programs, different grades of material they buy, etc. In my opinions there are to many variables to smelting for it to get as close as you can to 100 percent recovery. There is going to be waste and material up the stack and into the baghouse. IMO.
Hmm when a laboratory can assay gold in parts per million from a ton of ore not much if any loss there if any at all.
Greenwood B.C. ran a large gold smelter early 1900's, there are huge slag piles everywhere and not a gram of gold to be found in the slag, someone must have been doing something right.
