·Frothers for Mineral Processing Free download as PDF File pdf Text File txt or view presentation slides online This document discusses hydrophobic frothers used in mineral processing It provides an overview of Moly Cop Adesur s experience developing new frother chemistries Frothers are classified by particle size interaction kinetics rate using
Frothing agents also known as frothers are crucial in mineral processing for the froth flotation method which separates valuable minerals from the ore Frothers create a stable froth layer at the top of the flotation cell allowing the desired minerals to be separated from waste material Various frothers categorised by strength and
·Inhibition of bubble coalescence is of fundamental importance in a flotation process because it determines the size of bubbles and foam stability For this work commercial frothers have been selected MIBC DF 250 DF 400 and DF 1012; and NaCl as inorganic electrolyte Surface tension measurements used to characterize the tested frothers revealed

·Mineral Processing 38 2004 13 22 w j Froth flotation process requires the use of frothers These important flotation agents are commonly characterized as either selective or
There are two general categories of compounds used commercially as frothers in mineral/coal froth flotation The first category is the group that acts in a flotation system as both collector and frother and is normally associated with nonsulfide mineral flotation The second category is the nonionic or neutral frothers that do not specifically
·In a number of applications froth flotation in brines and in seawater frothers are used in concentrated electrolyte solutions Flotation of potash ores is carried out in a NaCl KCl saturated brine which is a solution of 6 7 mol of NaCl KCl/ surface tension measurements carried out with MIBC under such conditions Laskowski et al 2003 revealed
The fate of flotation reagents such as collectors promoters frothers and flocculants during process water recycling has also been Results show that process water concentrations of these reagents vary from plant to plant but that with the exception of frothers most reagents are generally removed from the system through
Frothers act to stabilise air bubbles so they remain well dispersed in the slurry and form a The minerals industry appears slow to adopt the use of image processing applications and more comprehensive flotation models in industrial APC applications Agnico Eagle Fosterville Gold Mine Fosterville operates a gold plant in Australia
