Doplňující informace
| Significance and Use | ||||||||||||||||||||||||||
|
5.1 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 concentrations. 5.2 This test method is a comparative referee method for compliance with compositional specifications for metal concentration or to monitor processes. It is assumed that all who use this method will be trained analysts 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. |

|
1.1 This test method covers the determination of gold in ore processing cyanide solution in the range from 0.3 μg/mL to 10.0 μg/mL of gold by direct aspiration into an atomic absorption spectrometer. 1.1.1 This test method may also be applied to cyanide leach solutions from metallurgical evaluation procedures. 1.2 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 standard 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
to establish appropriate safety and health practices and determine
the applicability of regulatory limitations prior to use.
