Ann: STRONG ZINC RECOVERY IMPROVEMENT, RECORD METAL PRODUCTION, page-3

NCZ seem to be getting screwed with treatment charges. Glen core are using the Alvionprocess to produce LME grade cathode zinc. Perhaps NCZ should do the same so they can keep the treatment charges for themselves.

ive copied an extract from a paper to below.

MIM began pilot testing of an Albion ProcessTM circuit to recover zinc as cathode from the McArthur River concentrate in 2001. In the flowsheet developed, zinc was leached in the Albion Process and recovered as cathode using a conventional purification/electrowinning circuit, with lead and silver reporting to a residue that could be sent to a smelter for lead recovery. Development of this project was continued by Xstrata following the takeover of MIM Holdings in 2003, and this has now led to the construction of two Albion ProcessTM plants in Zinc and Germany. These plants will be discussed in the next section of this paper.
