Names Of Heavy Liquids For Mineral Separation

There are two Franz magnetic separators with variable magnetic field strength, sample feed-through rate, and angle and tilt of sample feed-through. Heavy liquid separation equipment includes separatory funnels and vacuum flasks. The mineral separation laboratory uses the non-toxic compound Na-polytungstate for heavy liquid separations.
