1.1 This test method is for the determination of gold in copper concentrates in the concentration range from 0.2 to 17 g/g (0.007 to 0.500 Troy oz/short ton). Note 1 - The lower scope limit is set in accordance with Practice E 1601.

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. For specific warning statements, see 11.3.1, 11.5.4, and 11.6.5.


In the metallurgical process used in the mining industries, gold is often carried along with copper during the flotation concentration process. Metallurgical accounting, process control, and concentrate evaluation procedures for this type of material depend on an accurate, precise measurement of the gold in the copper concentrate. This test method is intended to be a reference method for metallurgical laboratories and a referee method to settle disputes in commercial transactions.

It is assumed that all who use this test method will be trained analysts capable of performing common laboratory operations skillfully and safely. It is expected that the work will be performed in a properly equipped laboratory under appropriate quality control practices such as those described in Guide E 882.
