Proper disposal or replenishment of gold toner

[Mainecoonmaniac]

I'v exhausted my first batch of Bostick and Sullivan's gold toner. Is it safe to toss it down the drain or store it for proper disposal? Or can I just replenish it like selenium toner?

Thanks tnp651. I just bought The Book of Alternative Photographic Processes By Christopher James. The book says I could replenish it by adding 50ml of .2% gold chloride and 50 ml of .2% ammonium thiocyanate per used liter of exhausted gold toner. He also recommends filtering the used solution with a coffee filter to strain out particulates. I've replenished selenium toner and it works well.
