It will help you how to do the froth flotation test in the laboratory. Please note that, in this video, we took coal as sample, different sample may need different agitation time for get good test result.

The steps:

1. weight 150g ore sample

2. pour the sample into the flotation tank

3. add water to the first scale

4. install the flotation tank on the laboratory flotation machine

5. agitating the sample

6. get the collector

7. get the frother

8. continue to add water to the second scale

9. time starts

10. after 2 minutes, add the collector

11. then, after 1 minutes agitating, add frother

12. then after 10 seconds agitation, open the inflatble valve and scraping the foam
