  • Tin Wikipedia

    Tin is a chemical element with the symbol Sn (from Latin: stannum) and atomic number 50. Tin is a silvery metal that characteristically has a faint yellow hue. Tin, like indium, is soft enough to be cut without much force. When a bar of tin is bent, the so-called “tin cry” can be heard as a result of twinning in tin crystals; this trait is shared by indium, cadmium, and frozen mercury.

    Sep 01, 2016· The Sn and Sb in a high Au, Ag, Pd, Sn, Pb and Sb bearing decopperized anode slime had no obvious detrimental effect on thiosulfate leaching of the precious metals, but the Pb could cause seriously detrimental impact. Only 37.3% of Au, 69.2% of Ag and 43.8% of Pd in the decopperized anode slime could be extracted by direct thiosulfate leaching.

    Mining Mining Dredging: Dredging is the underwater excavation of a placer deposit by floating equipment. Dredging systems are classified as mechanical or hydraulic, depending on the method of material transport. The bucket-ladder, or bucket-line, dredge has been the traditional placer-mining tool, and it is still the most flexible method for dredging under varying conditions.
