Mark Dopson,Anna-Kaisa Halinen,Nelli Rahunen,Dan Boström,Jan-Eric Sundkvist,Marja Riekkola-Vanhanen,Anna H. Kaksonen,Jaakko A. Puhakka +7 more
TL;DR: The potential negative impact of silicate mineral dissolution on heap bioleaching is demonstrated by microbial inhibition and liquid flow by demonstrating that inhibition of Fe2+ oxidation during column leaching of two of the chalcopyrite ores was due to fluoride toxicity.

Silicate mineral dissolution in the presence of acidophilic microorganisms: implications for heap bioleaching
TL;DR: In this article, the amenity of five silicate minerals to chemical and biological dissolution was tested in the presence of either Ferroplasma acidarmanus Fer1 or Acidithiobacillus ferrooxidans with olivine and hornblende being the most and least amenable, respectively.

Interpretation of the composition of trioctahedral micas
TL;DR: In this article, structural formulas calculated for more than 200 published analyses of phlogopites, biotites, siderophyllites, and lepidomelanes indicate that the additional positive charges carried by trivalent cations proxying for bivalent Mg in the octahedral group of trioctahedral micas are accommodated in two different ways, (1) by a positive charge on the octagonal layer, which is neutralized by an equivalent increase in the negative tetrahedral charge (increased replacement of Si by Al), and all
