Standard Test Methods for Determination of Gold in Cyanide Solutions

Importancia y uso:

4.1 In primary metallurgical processes for gold bearing ores, gold is extracted with an alkaline cyanide solution. Metallurgical accounting, process control, and ore evaluation procedures depend on accurate, precise, and prompt measurements of the gold levels.

4.2 These test methods are comparative referee methods for compliance with compositional specifications for metal amounts or to monitor processes. It is assumed that all who use these methods will be trained users capable of performing common laboratory procedures skillfully and safely. It is expected that work will be performed in a properly equipped laboratory under appropriate quality control practices such as those described in Guide E882, and that proper waste disposal procedures will be followed.
