Just wondering what the consensus was surrounding non phenolic hot mounting resins? Is this something that is likely to take off in the coming years as a result of increased safety fears about phenolic fumes being given off in baking?

How can we extract Fe from a pyrite magnetite ore having this characteristics? All I can think is magnetic separation but I guess its wrong because I need Fe concentrate. Using that separation, maybe its inefficient. Please help
Last replied to by jpearcy
Ian, you could use magnetic separation as 80% of the Fe is Magnetite. If you wanted to increase recovery, flotation coul...
