Aka hooter,
Regarding the metallurgy of the native copper ores of AOH and CDU. From http://www.rcresearch.com.au/pdf/URL_Company_Review_29102009.pdf
"Metallurgy: Roseby is a ‘non conventional’ resource due to ~70% of current reserves being nonsulphide native copper mineralisation. Whilst native copper floats very well, PFS and DFS testwork has confirmed it exhibits lower recoveries (~60%) compared to the sulphide deposits (~96%) due to ~30% of copper locked in the crystal lattice of biotite mica."
Has there been reference to the, "lock up in crystal lattice of biotite mica", in the CDU metallurgy reports?
