Complete text of publication follows. This topic involves the determination of Pt and Pd content of precious metal-bearing rocks (from the Sudbury magmatic complex) by inductively coupled plasma spectrometric methods. Altogether 9 samples were available for the com
Here advantage is taken during the extraction of other precious metals such as f.e. copper or zinc where also small quantities of gold are found in the extracted rock. In the process of the electrolytic cleaning of the rock sludge the anode activates the precious metal bearing rock sludge. The cathode is made of a piece of pure metal. Get price

03-10-2012· For those wondering about melting metals – well, now you know. Different melting points for different precious metals. Something to think about when soldering, fusing, forging hot metal. We didn't comprise this. Thanks to someone at the Jewelry Artist's Network who did. It's valuable information and deserves a mention.
Pyrite, galena, sphalerite, and chalcopyrite are all common sulfide minerals that are found in many precious metal veins and other hard rock deposits. When metals combine with sulfur, the resulting mineral is called a sulfide. These minerals are the most important sources of most base metals like copper, lead and zinc.
