Guide for Cyanide Management

ASTM D7728, Guide for Selection of ASTM Analytical Methods for Implementation of International Cyanide Management Code Guidance, was developed by Subcommittee D19.06 on Methods for Analysis for Organic Substances in Water, part of ASTM International Committee D19 on Water.

ASTM D7728 will provide code users with guidance on the selection of ASTM analytical methods used to measure cyanide concentrations in solution. The test methods referenced in ASTM D7728:

• Control and optimize the use of cyanide in the gold leaching process;

• Protect wildlife when solutions are released into open impoundment facilities;

• Define the cyanide concentration in process solutions used to select proper personal protection equipment; and

• Protect human health and aquatic wildlife from environmental releases in water and groundwater discharges.

ASTM D7728 will help users, regulatory agencies and the international community to select the proper cyanide methods for the intended purpose in analysis of metallurgical processing solutions. The new standard will also provide guidance in sampling, preservation and interpretation of results.
