Effects of Additives in Froth Flotation of Silicate Zinc ...

2014-5-2 · Froth flotation is an ore dressing method. Normally, the surface of ore particles in suspension are modified to be hydrophobic by adsorption of some additives. The air is flowed into the suspension forming bubbles on which ore particles are attached. These bubbles flood up to the surface of the suspension forming a film called “froth”,
