Froth collectors examples
WebThe present invention relates to novel fatty acid derivatives and the use of these derivatives as collectors for the froth flotation of non-sulphidic ores, especially phosphate ores. ... However there is a need for new formulations of collectors for complex, for example weathered, ores, which are selective, based on renewable raw materials and ... Webpulp. The collector should coat only valuable mineral particles so that water is repelled and bubbles can become attached upon collision. Air bubbles act like 'hot-air balloons' providing the necessary buoyancy to carry selected minerals to the pulp surface. Collector addition also affects froth formation. Too much can inhibit froth stability and

Web(i) Frothing Agent : Examples: Mainly fatty acid, pine oil and eucalyptus oil are good frothing agent. (ii) Collector/ Floating Agent: Main floating agent is sodium ethyl xanthate. (iii) Stabilizers: Examples : Cresol and aniline (iv) Activator: Example : Copper sulphate (CuSO 4) (v) Depressant : Example: Sodium cyanide (NaCN), Base (Na 2CO 3). WebThe volume of froth generated in the flotation machine under standard operating conditions is often referred to as froth power. The froth power is influenced by the type of collector and frother used. Acidic frothers perform well only in acid pH. Typical examples of these reagents are phenols and alkyl-lauryl sulfonates.
