Flotation performance and adsorption mechanism of a .

1/7/2020· The micro-flotation tests were conducted in a 50 mL flotation cell of a XFG II50 laboratory flotation machine. A 5 g quartz sample was put in the flotation cell filled with ultra-pure water. The pulp was stirred for 3 min at a rotation speed of 1992 rpm, and then the pH regulator (0.10 mol/L HCl or NaOH solution), activator CaCl 2, and collector 2-CLA were added to the cell in sequence.

Scheelite - Wikipedia

Scheelite is a calcium tungstate mineral with the chemical formula Ca W O 4.It is an important ore of tungsten (wolfram). Well-formed crystals are sought by collectors and are occasionally fashioned into gemstones when suitably free of flaws. Scheelite has been synthesized using the Czochralski process; the material produced may be used to imitate diamond, as a scintillator, or as a solid ...
