  Pyrite enhanced chlorination roasting and its efficacy in gold …

  2020111 · Here, we show that addition of pyrite could promote calcium chloride oxidation to produce chlorine gas, and the process realized the recovery of gold (Au) and silver (Ag) from gold tailing in an efficient and environmentally friendly way. Notably, addition of pyrite also has the potential to enhance the chlorination roasting in other fields.
