Y&X Beijing Technology Co., Ltd provides various kinds of flotation reagent, including flotation collectors, flotation frothers, regulators, etc.

 

Our flotation reagents are widely used for copper, lead, nickel polymetallic sulfide ore, non-sulfide ore and precious minerals like gold and silver, aiming to help miners improve their flotation process as well as raise uselful minerals' recovery rate. Up to now, we have served both at home and abroad, with products exported to many countries.

 

“Collectors”, also known as “promoters”, are organic compounds which make the surface of certain selected minerals water repellent. These reagents are added to the pulp in the conditioner tank and ball mill. The mineral surface absorbs the collectors during conditioning period making them hydrophobic. Froth is formed when they come in contact with flowing air bubbles and float to the surface. Sodium Isopropyl Xanthate and Potassium Amyl Xanthate are the commonly used collectors.

 

“Frothers” are surface-active chemicals that concentrate at the air-water interface. It prevents air bubbles from coalescing or bursting by lowering the surface tension of the slurry. Frothing properties can be persistent or nonpersistent depending on the desired stability of the froth. Pine oil and alcohols such as MIBC are most commonly used frothers.

 

“Regulators” or “modifiers” are used to modify the action of the collector by intensifying or reducing water-repellent effect of mineral surface conditions. This is done to assist in the selective flotation of minerals. Regulators can be classed as activators, depressants, or pH modifiers. Regulators may activate poorly floating minerals such as sphalerite by adding readily soluble copper sulfate. Similarly regulators can depress certain minerals rendering it hydrophilic and preventing their flotation. Minerals like pyrite and arsenopyrite can be depressed by adding sodium cyanide or lime, so that a differential flotation can be performed on a complex ore.
