Question

Give the name and role of collector and froth stabilizer in froth floatation process.

Answer 1

The name of collector is Pine oil, Sodium ethyl Xanthate and the name of froth stabilizer is Aniline, Cresol.

• In froth flotation process, the role of collector (Pine oil, Sodium ethyl xanthate) is it attracts the ore particle on the surface of the froth. This mechanism takes place by surface adsorption.
• In froth flotation process, the role of froth stabilizer (Aniline, Cresol) is it stabilizes the froth.

Answer 2

Answer:

collector(pine oils,fatty acid,xanthates,etc.) enhance non-wettability of mineral particles.

froth(cresols,aniline) stabilise the froth.

Explanation:

minerals particle wet by oils while gangue particle wet by water. As a result,froth carries the mineral particles.It is then dried for recovery of the ore particle.
