Non chromatographic extraction Froth flotation.pptx

Froth flotation separation

1. Sanjivani College of Pharmaceutical Education and Research, Kopargaon Pharmacognosy & phytochemistry-II Dr. Sutar N. G Associate Professor

2. Froth flotation based on principle of difference in wetting property of ore and gangue particle water and oil eg. - Sulphides ore

3. Air Oil Water Sulphides gangue

4. Froth flotation based on principle of difference in wetting property of ore and gangue particle water and oil eg. - Sulphides ore Air

5. Sulphide Gangue Rotation of disc cause size reduction Gangue particles are attracted by water and become Havier Sulphide particles are attracted by oil and become lighter Sulphides separated at upper phase by oil, air bubbles Gangue separated at lower phase by water Oil droplets Water drop-lets
