Conclusion. From the results of this investigation, the following conclusions can be drawn: (1) Calcite particles produced by ceramic media grinding adsorb more NaOL, resulting in a better floatability than those produced by steel media grinding. (2) In the case of steel media grinding, the hydrophilic Fe (0), Fe (II), and Fe (III) species were ...

A quartz-type fluorite ore in western Henan contains 41.58% of CaF 2 and 45.76% of SiO 2. The granularity of the inlay is uneven. Part of the fine-grained fluorite is wrapped by quartz and feldspar, which brings certain difficulties to the upgrading of fluorite. A comparative study of process mineralogy, the flotation reagent system and the ...
