Fluorite in refractory multiple metal recycling sorting process characteristics of fluorite

Glass is reasonable, it is an effective inhibitor of calcite, and fluorite can be floating on little influence. As compared with the floatability of quartz fluorite, calcite is poor,[link widoczny dla zalogowanych], 'as long as the selected nature of the pulp in the rough, did not join the high-priced metal salts, in order to avoid the activation of metal ions on quartz, water glass, etc. through the selection and processing can effectively inhibit the floating quartz. 4 Conclusion of the two main types of refractory polymetallic ore fluorite fluorite discussion of sorting features can be summarized as follows: (1) of a fluorite barite quartz an Ore-type major increase in the water glass roughing suppression of silicon and aluminum sulfate, and the inhibition of barite mainly by reducing the pH value or adding a similar selection of barite HX inhibitors to achieve their goals. Structure in the process to take the ore concentrate to return or give up some of the high impurity can be avoided in the barite ore vicious cycle and improve the fluorite concentrate indicators. (2) of a fluorite, calcite, quartz type A Ore, in CaF2/Ca (Z) 3 is very small (≤ 1), should be taken to extreme pressure in the roughing caa pharmaceutical programs,[link widoczny dla zalogowanych], by adding H2SO, can reduce the activity of calcite , plus acidic water glass and the like A-1 of the auxiliary agent can inhibit calcite, fluorite flotation enhancement. (3) Regardless of which type of ore,[link widoczny dla zalogowanych], should be avoided in neutral or weak acid medium, addition of a large number of high-priced metal salt. Because in this medium, negative hydrolysis of salts 3 Li and other school items: hard for multi-disk recovery is not near the quarry Ying process characteristics of fluorite gangue of 31 to inhibit the flocculent hydroxide, Instead of the ions.
