A case study of the ambient oxidation of two zinc-lead (sulphide) reference ores.
The history of two lead-zinc (sulphide) reference ores is presented to show quantitatively the serious effects of ambient oxidation on unprotected samples. This study should serve as a warning to the users and producers of sulphide-bearing reference ores and concentrates. Suggestions are given for overcoming or diminishing the oxidation problem.
