Quantitative determination of elemental sulfur at the arsenopyrite surface after oxidation by ferric iron: mechanistic implications

Geochemical Transactions, 2001
The elemental sulfur formed at the arsenopyrite surface after oxidation by ferric iron was quantitatively measured by extraction in perchloroethylene and subsequent quantitative analysis by HPLC.

Chemical Oxidative Kinetic Study of Arsenopyrite Dissolved by Iron Solution

, 2013
To extract the Au efficiently, the kinetic experiments were performed in a 1000 mL-glass bulbs which were made by us to determine the oxidative dissolution of arsenopyrite by iron solution.

Characterisation of pyrite and arsenopyrite surface species in aqueous systems for selective flotation

, 2021
Data source: , Available on requestIn most auriferous hydrothermal deposits, gold is preferentially associated with pyrite and arsenopyrite minerals, with higher economic gold values noted for the latter and arsenian pyriteminerals.
