Keeping Standards up-to-date
Standards are living documents which reflect progress in science, technology and
systems. To maintain their currency, all Standards are periodically reviewed, and
new editions are published. Between editions, amendments may be issued.
Standards may also bewithdrawn. It is important that readers assure themselves
they are using a current Standard, which should include any amendments which
may have been published since the Standard was purchased.
Detailed information about Standards can be found by visiting the Standards
Australia web site at www.standards.com.au and looking up the relevant Standard
in the on-line catalogue.
Alternatively, theprinted Catalogue provides information current at 1 January each
year, and the monthly magazine, The Australian Standard , has a full listing of
revisions and amendments published each month.
We also welcome suggestions for improvement in our Standards, and especially
encourage readers to notify us immediately of any apparent inaccuracies or
ambiguities. Contact us via email atmail@standards.com.au, or write to the Chief
Executive, Standards Australia International Ltd, GPO Box 5420, Sydney, NSW
2001.

This Standard was issued in draft form for comment as DR 01205.

PREFACE
This Standard was prepared by the Standards Australia Committee MN-005, Copper, Lead,
Zinc, Gold and Silver Ores and Concentrates as part of a programme of standardizing methods
for the determination of elements of commercial interest in such materials.
The objective of this Standard is to provide those involved in the analysis of zincsulfide
concentrates with a standardized method of determining gold content supported by precision
data obtained from an inter-laboratory test programme.
This Standard is identical with and has been reproduced from ISO 13658:2000, Zinc sulfide
concentrates— Determination of zinc content— Hydroxide precipitation and EDTA titration
method, which has been prepared by ISO/TC 183 Copper, Lead andZinc Ores and
Concentrates. Australia holds the Chairmanship and Secretariat of ISO/TC 183 and has made a
significant contribution to the preparation of ISO 13658.
As this Standard is reproduced from an International Standard, the following applies:
