Fluorspar for iron and steel making should carry at least 85 per cent calcium fluoride and preferably more, and it should be free from sulphides and sulphates. For most other chemical uses it should contain 95 to 98 per cent or more of calcium fluoride. The following analyses of gravel fluorspar, most of them made in ...

Rare Earths: Altona advances Monte Muambe to PFS stage
Given that Monte Muambe hosts fluorspar as well as rare earths, there is clearly a possibility that it could also produce, in addition to MREC, a fluorspar concentrate by-product. Fluorspar might even provide an alternate route into production for the project. "We are currently starting a review of Monte Muambe's fluorspar potential ...
