Welcome to the forum David.
I'm in agreement with Goran on this subject. Whichever way you refine you make some nasties and are left with some waste that can't be recycled easily. We try very hard on the forum to push safety and environmental concerns to all members and some members, Butcher leaps to mind, manage to reuse much of the materials used and created. The big refiners can and do recover and refine much more than we can by sheer scale of economy but we can play our part in the waste stream. The membership generally recover and refine the easier treated materials saving the balance to sell on to bigger operators who have the necessary controls and equipment to treat this material, they also sort and sell the base metals etc which if done well finances the whole operation the value bearing material kept been a small part of the whole. Whichever method we use it sems to me that we are helping to avoid filling landfills and the need for even more mines and the energy needed to run them and process their product. Not all our members refine we have many that collect, sort and either sell or send for toll refining, there's room for all and the forum can pint you in the right I reaction to help you decide hat is right for you.
Good luck.
