Scheelite flotation: a new scheme using oleoyl sarcosine ...

Scheelite was selectively floated from a low-grade calcitic run-of-mine ore (containing 0.28% WO 3, 96.3% CaCO 3 and 2.24% SiO 2) with a 70.6% WO 3 grade and a 70% recovery, using oleoyl sarcosine as collector, quebracho as depressant and alkyl oxine as modifier. A new scheme was developed in laboratory scale experiments to reach this grade and recovery.

Modeling the Competitive Adsorption of Water and Methanoic ...

Atomistic simulation techniques were used to investigate the interaction between the minerals calcite and fluorite with water and methanoic acid. The relative adsorption energies suggest that methanoic acid preferentially adsorbs onto fluorite surfaces, while adsorption of water is energetically preferred over methanoic acid on the calcite cleavage plane in agreement with experiment.

Flotation Research of a Fluorite Ore - Scientific.Net

Separating fluorite from quartz and calcite by forth flotation can be both in weak-acidized (pH 6.0) condition and weak alkali (pH 9.0) condition. The experiment results have shown that ZnSO4 can decrease the depression that water glass works on the fluorite, and acidized water glass has a selective inhibition on the silicate minerals. The close flowsheet protocolled in the experiment can ...
