Processing High-Grade Concentrates from Challenging Low-Grade Iron Ore
On an average global basis, iron ores tend to decrease in Fe grade over time. With the exception for some deposits that are logistically challenged, iron ore resources in more accessible areas may often have processing issues, especially if high-grade concentrates are desired. This paper addresses some of these with examples on how …

Gold concentrate marketing 101
Gold ore may be transformed to concentrates for one of several reasons. If the ore is refractory (not free-milling) and the capex of a pressure oxidation (POX) or (bio-oxidation) BIOX plant cannot be justified, a mine's only recourse may be the production of a concentrate. Even free-milling ore may be channelled to a concentrate stream if ...
