Go ld analyse

When Associate Professor  

Paul Haddad began pure  

research project studying  

cyanide complexes he had  

little idea he would excite the  

interest of Australia’s gold  

mining industry.  

Now, the industry tells him he  

has produced technique which  

has the potential to save it up to  

$4O million year reduced  

chemical costs and further  

unknown but possibly huge amount  

through reducing the likelihood of  

 

environmental damage  

Professor Haddad technique,  

which uses off-the-shelf items and  

common analytical process  

known as reversed-phase ion-inter-  

ac mn chromatography (RPIIC). is  

valued by the gold mining industry  

because it can tell the miner, with  

previously unattainable accuracy.  

how much cyanide is present at any  

slage of the gold extraction process.  

But that is only the beginning.  

Professor Haddad technique  

can be adapted to on-line analysis,  

meaning it can monitor production  

flows and it can analyse up to 10  

cyanide complex ions simultane-  

ous Z;  

This is capability the gold  

mining industry has sought for  

ear i;  

The most efficient method of  

extracting fine-grained go from  

crushed rock is known as carbon-  

m-pulp in which cyanide solu-  

tion is added to the crushed gold  

ore ...  

The cyanide reacts with the  

gold to form soluble gold cyanide  

solution. which is then absorbed on  

to carbon pulp. The gold is then  

stripped from the carbon pulp,  

which is recycled but there is  

possibility that cyanide could  

escape into the environment.  

Depending on the form it is in,  

cyanide can be extremely toxic, so  

is essential that gold miners know  

exactly where their cyanide is, and  

wh form 11 15 ’ throu hout 016

just what Professor  

Haddad’s instrument does. But, not

UNSW/St George Institute of Education:  

Memorandum of  

Agreement signed  

The University of NSW  

has signed Memorandum of  

Agreement which will result  

in the St George Institute of  

Education being absorbed  

into the University’s Faculty  

of Professional Studies.  

At its meeting on February,  

Council resolved that the Univer-  

sity endorses the proposal that the  

St George Institute of Education  

(Sydney College of Advanced Edu-  

cation) be integrated into the  

University of NSW.  

The Vice-Chancellor, Profes-  

sor Michael Birt, was requested at  

that time to continue discussion on  

details of association.  

In document prepared in  

February this year, the Vice-  

Chancellor said draft Memoran-  

dum of Agreement was being  

prepared on the basis that the  

consolidation would be to the  

mutual benefit of the parties and to  

the community; that professional  

education (including that available  

to members of staff) and research  

in various fields would be  

enhanced.

Microbiologists tackle  

marine fouling problem  

Marine fouling costs world  

shipping billions of dollars for  

extra fuel usage, cleaning and  

repainting each year,  

according to Professor Kevin  

Marshall at UNSW’s School  

of Microbiology. Ravenous  

marine bacteria constantly  

ply our oceans and inland  

waterways looking for  

nutrient-bearing surfaces to  

adhere to.  

Once glued on to hapless  

vessel they lose no time in gelling  

down to good feed, doubling in  

size before starting to reproduce  

in huge numbers to form surface  

slime (or biofilm), Professor  

Marshall said.  

These growing bacteria excrete  

organic molecules that attract algal  

and barnacle larvae and if the  

colonising process goes on unhin-  

dered, lire host vessel will be on live  

way to continually reduced speeds  

because of increasing fluid fric-  

tional resistance.  

In addition, corrosion of metal  

surfaces occurs under microbial  

slimes, Professor Marshall said,  

citing "micro-fouling' ’ and corro-  

sion as reason why Norwegian  

oil rig recently toppled over in the  

North Sea.

the ancient alchemists had had reversed-phase ion-interaction chromatography.  

UNSW Vice-Chancellor, Professor  

Michael Birt, signs the  

Memorandum of Agreement
