AS 2862.1:2021 PDF Download

The ISO 12743:2021 standard was adopted as AS 2862.1:2021. The fundamental techniques for sampling copper, lead, zinc, and nickel concentrates from both moving streams and stationary lots are described in this standard.

To ensure representative samples are obtained for further chemical analysis, physical testing, and measurement of moisture content, the standard gives instructions on several sampling techniques, including stopped-belt sampling. The standard's sample practices adhere to pertinent international standards.

The standard highlights the use of an ordinary and adequately accurate sample for moisture determination and chemical analysis in situations where the concentrates being sampled are susceptible to oxidation or breakdown. This method offers precise and trustworthy results while assisting in the elimination of prejudice.

It's vital to note that any particular requirements and methods mentioned in AS 2863 should be followed for moisture determination and chemical analysis. In order to assure correct assessment of the metal and moisture content of copper, lead, zinc, and nickel concentrates, AS 2862.1:2021 is a comprehensive standard that strives to provide uniform and reliable sampling techniques.
