Hi there. I have a lot of gold filled jewellery scrap. I have gone the nitric acid leach, followed by AR route in the past. Mixed results. Lots of stuff doesn't dissolve in nitric and then messes up the AR step. My question: Can you start with one or more hydrochloric acid leaches?

Geo, I know you wrote this comment in 2011. I forgot to add that prior to the leach, I soak the materials in a 50/50 HCI and H2O solution. According to the Igoli method this is suppose to rid the leach of a lot of the iron and sulfur content. I pour this off prior to the actual chlorine and hydrochloric being added.

Chlorination Process for Gold. This process was based on the fact that chlorine, in the presence of moisture, converts gold into the trichloride AuCl3, which is soluble in water and removed by washing, the gold being then precipitated by ferrous sulphate, sulphur dioxide, hydrogen sulphide, or charcoal.
and flaws. High-pressure grinding is the optimal process for removing scale, cracks and other surface defects. Grinding large-scale rounded parts however, requires specific grinding facilities. Machines generally have extremely high driving power, between 50 and 630 kW. The grinding speed is generally 80 m/s. WORKPIECE TEMPERATURE
