ASTM E1600-15 PDF Download

Guidelines for precise and accurate measurements of gold contents in alkaline cyanide solutions are provided by the ASTM E1600-15 standard. These measures are essential for initial metallurgical operations for gold-bearing ores, as well as for metallurgical accounting, process control, and ore evaluation.

The test procedures outlined in this standard are comparative referee procedures used to verify that compositional parameters for metal concentration are being followed as well as to keep an eye on processes. The standard makes the assumption that those who utilize these methods are skilled laboratory technicians who have received the proper training. It also highlights how crucial it is to work in a lab that is adequately furnished and to adhere to the right quality control and waste disposal techniques.

The standard covers the detection of gold using two separate techniques in cyanide solutions used for ore processing within defined concentration ranges. While the Flame Atomic Absorption Spectrometry (FAAS) method may detect quantities of gold ranging from 0.300 to 10.0 g/mL, the Inductively Coupled Plasma Mass Spectrometry (ICP-MS) method can detect concentrations of gold ranging from 0.001 to 0.500 g/mL. Metallurgical evaluation procedures' cyanide leach solutions can also be treated with these techniques.

Within the standard, the test methods are laid out in a particular order. The ICP-MS method is discussed in parts numbered 17 to 24, whereas the FAAS method is discussed in sections numbered 9 to 16.
