Due to their similar surface properties and good floatability, the separation of scheelite from fluorite is particularly difficult. These ores are usually processed at basic pH using sodium silicate as a gangue mineral depressant and a fatty acid as the collector. Sodium ...

Silicates are converted to volatile SiF 4, which will be lost in open vessel digestion procedures. HF by itself is more effective in the digestion of silicate rock minerals than when mixed with another acid.
