Fix this textWhen Associate Professor
Fix this textPaul Haddad began a pure
Fix this textresearch project studying
Fix this textcyanide complexes he had
Fix this textlittle idea he would excite the
Fix this textinterest of Australia’s gold
Fix this textmining industry.
Fix this textNow, the industry tells him he
Fix this texthas produced a technique which
Fix this texthas the potential to save it up to
Fix this text$4O million a year m reduced
Fix this textchemical costs and a further
Fix this textunknown but possibly huge amount

Fix this textProfessor Haddad s technique,
Fix this textwhich uses off-the-shelf items and
Fix this texta common analytical process
Fix this textknown as reversed-phase ion-inter-
Fix this textac mn chromatography (RPIIC). is
Fix this textvalued by the gold mining industry
Fix this textbecause it can tell the miner, with
Fix this textpreviously unattainable accuracy.
Fix this texthow much cyanide is present at any
Fix this textslage of the gold extraction process.
Fix this textBut that is only the beginning.
Fix this textProfessor Haddad s technique
Fix this textcan be adapted to on-line analysis,
Fix this textmeaning it can monitor production
Fix this textflows and it can analyse up to 10
Fix this textcyanide complex ions simultane-

Fix this textThis is a capability the gold

Fix this textThe cyanide reacts with the
Fix this textgold to form a soluble gold cyanide
Fix this textsolution. which is then absorbed on
Fix this textto carbon pulp. The gold is then
Fix this textstripped from the carbon pulp,
Fix this textwhich is recycled but there is a
Fix this textpossibility that cyanide could
Fix this textescape into the environment.
Fix this textDepending on the form it is in,
Fix this textcyanide can be extremely toxic, so
Fix this texth is essential that gold miners know
Fix this textexactly where their cyanide is, and

Fix this textof Professional Studies.
Fix this textAt its meeting on 6 February,
Fix this textCouncil resolved that the Univer-
Fix this textsity endorses the proposal that the
Fix this textSt George Institute of Education
Fix this text(Sydney College of Advanced Edu-
Fix this textcation) be integrated into the
Fix this textUniversity of NSW.
Fix this textThe Vice-Chancellor, Profes-
Fix this textsor Michael Birt, was requested at
Fix this textthat time to continue discussion on
Fix this textdetails of association.
Fix this textIn a document prepared in
Fix this textFebruary this year, the Vice-
Fix this textChancellor said a draft Memoran-
Fix this textdum of Agreement was being
Fix this textprepared on the basis that the
Fix this textconsolidation would be to the
Fix this textmutual benefit of the parties and to
Fix this textthe community; that professional
Fix this texteducation (including that available
Fix this textto members of staff) and research
Fix this textin various fields would be
Fix this textenhanced.
