Abstract
Overview
ISO 8658:1997 specifies a laboratory method for the determination of trace elements in green and calcined coke intended for aluminium production. The method uses sample ashing, fusion, dissolution and measurement by . It is written for coke with ash ≤ 1% (m/m) and defines procedural steps, required reagents and apparatus to obtain reliable trace-element results relevant to aluminium smelting feedstocks.
