Introduction
Christian first of all. After that, I am a lover of most branches of science and pretend to be an artist on occasions as well (Instagram @rjsymes_art). Lived on a farm most of my life and grew up gardening and brewing weird chemical concoctions whenever I got the chance.... it's a wonder I'm still alive! Always trying to learn something new.

Article
The Fosterville Goldmine in Victoria Australia employs the BIOX® Process to liberate gold from its sulphidic flotation concentrate through bacterial oxidation. Gold occurrence is primarily as submicron particles in pyrite and arsenopyrite and has been described as being in ‘solid solution’ and therefore not amenable to direct cyanidation. Once libe...

Gold occurrence is primarily as submicron particles in pyrite and arsenopyrite and has been described as being in ‘solid solution’ and therefore not amenable to direct cyanidation even with fine grinding.

Question
I've been using sodium dithionite as a reducing agent for silver nanoparticle generation.
It also appears to work for copper.
However, I am trying to cap the nanoparticles with various molecules and it occurred to me that oxidation products of the dithionite might be interfering.
Has any had any experience with using dithionite for this?
