Question

what are collectors in froth flotation process? give two examples

Answer 1

In froth flotation the effectiveness of an air bubble to adhere to a particle is based on how hydrophobic the particle is. Hydrophobic particles have an affinity to air bubbles, leading to adsorption. ... Collectors are the main additives used to improve particle surfaces. The hydrophobic particles attach to the air bubbles, which rise to the surface, forming a froth. ... Froth flotation efficiency is determined by a series of probabilities: those of particle–bubble contact, particle–bubble attachment, transport between the pulp and the froth, and froth collection into the product launder. refer ncert for example..
