The instrument model is MultiMode 8. The probe material is Silicon Tip on Nitride Lever and the probe model is SCANASYST-AIR. It is difficult for a scheelite crystal to naturally dissociate into a flat surface (Gao et al., 2016). To get a flat surface, it needs to polish scheelite with a polishing machine (Tegramin-25, Struers).

The results showed that scheelite floated only 50 % of BHA. The adsorption capacity of BHA on the scheelite surface was 1.63 × 10 −5 mol/g, which caused the surface potential of scheelite to become negative, with a change of −10.5 mV at pH 9.05. After BHA adsorbed onto the scheelite surface, the surface roughness increased by …
