Frothers are liquids that produce the froth or foam on which the flotation process depends the froth resembles soap suds and provides the physical separation between the minerals floated and the pulp containing the waste the froth must be strong enough to support the weight of the mineral floated and yet not be tenacious and nonflowingMore Details
Below the surface the frothers create smaller more stable bubbles to maximise mineral attachment above the surface the frothers create a protective layer to prevent coalescence and maintain mobility nalco water offers a range of products to help you find the right balance of flotationMore Details

Frothing agents known as frothers may be introduced to the pulp to promote the formation of a stable froth on top of the flotation cell the minerals that do not float into the froth are referred to as the flotation tailings or flotation tailsMore Details
Flottec f100 series frothers product data sheet the main purpose of frothers in froth flotation is to cost effectively reduce bubble size and to stabilize the mineral laden bubble just long enough to remove it from the flotation cell with minimal detrimental effects on operability and graderecovery performanceMore Details
Wastewater froth flotation in wastewater treatment plants the flotation process called induced gas flotation is widely used to remove fats oils grease and other suspended solids from wastewater the goal of this process is primarily for removing oil from effluents of oil refineries chemical production petrochemical and natural gas processing plants and other similar industriesMore Details
Froth flotation involves thoroughly mixing finesize coal and water frothers and other conditioning reagents are added to the slurry and as air is bubbled up through the slurry the coal particles attach themselves to the bubbles and are carried to the surfaceMore Details
