Question

What are the froth stabilizers?

Answer 1

Froth stabilizers:

• Froth stabilizers are defined as a substance that is used to stabilize the froth in the froth flotation process.
• Cresols and aniline are used as froth stabilizers.
• It is a technique used for concentrating the ores.
• The impurities that are in ores are removed before processing to obtain the metal.
• Froth formation is short living so a froth stabilizer is used.

Froth Flotation Process:

• The process starts by wetting the metal with a liquid.
• A liquid that is used for wetting the metallic sulfides by pine oil.
• The finely powdered ore is added with water and pine oil.
• The vigorous agitation of the water causes froth formation.
• Ore is wet with oil and impurities are wetted with water.
• Froth will take ore and rinse and then is skimmed off.
