Discussion on the Micro-mechanism of Precious Metals Trapped inPyro-metallurgical Processes by Base Metals

Chen Jing

Strategic Study of CAE 2007, Volume 9, Issue 5,   Pages 11-16

Abstract:

The micro-mechanism of precious metals trapped in pyro-metallurgicaltheir mattes were discussed in present paper .It was forwarded that the reasons for trace amount of preciousother .Because the bonding electrons in the slag phases are all thought as the localized electrons, the preciousthe metal atoms.And because the electrons in the metal phases can move freely among the atoms, the preciousThe properties of the matte are in fact similar with that of metal at their melted state, therefore precious
