Gold In Pyrite

The images below show the distribution of gold and arsenic in a pyrite grain. There is clear zonation of gold and arsenic, following the broadly concentric shape of crystal growth zones seen under the microscope. In addition,W, Ni, Co and Bi are also weakly enriched in the Macraes pyrite, also with concentric zonation. ...

Aug 01, 1999 XANES measurements on gold-bearing arsenian pyrite from the Twin Creeks Carlin-type gold deposits show that gold is present as both Au 0 and Au (super I+) and arsenic is present at As (super I-) . Au 0 is attributed to sub-micrometer size inclusions of free gold, whereas Au (super I+) is attributed to gold in the lattice of the arsenian pyrite. STEM observations suggest that As (super I-) is ...
