Significance and Use | ||||||||||||||||||||||||||||||||||||||||
This guide is intended as a means for selecting the proper methods for measuring cyanide to conform to the International Cyanide Management Code guidance related to the analysis of cyanide bearing solutions. Cyanide is analyzed in process solutions and in discharges in order to apply code guidance; however, improper sample collection and preservation can result in significant positive or negative bias, potentially resulting in over reporting or under reporting cyanide releases into the environment. This guide contains comparative test methods that are intended for use in routine monitoring of cyanide. It is assumed that all who use methods listed in this guide will be trained analysts capable of performing them skillfully and safely. It is expected that work will be performed in a properly equipped laboratory applying appropriate quality control practices such as those described in Guide . |

1. Scope | ||||||||||||||||||||||||||||||||||||||||
1.1 This guide is applicable for the selection of appropriate ASTM standard analytical methods for metallurgical processing sites to conform to International Cyanide Management Code guidance for the analysis of cyanide bearing solutions. 1.2 The analytical methods in this practice are recommended for the sampling preservation and analysis of total cyanide, available cyanide, weak acid dissociable cyanide, and free cyanide by Test Methods , , , , , , , and . The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3 This guide does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard guide to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. |
