Over the last two decades, significant advances have been made in the field of chemical reagents used in froth flotation, a solids separation technique whose success depends on the use of a wide
May 25, 2021 Aalto researchers develop 'greener' flotation chemical. Researchers at Aalto University in Espoo, Finland, have developed a way to make mineral processing a little more environmentally friendly by replacing the frothers traditionally used in the flotation process.

Oct 19, 2016 Chemical reagents produce the hydrophobic film on the mineral particle surfaces. It is the primary driving force that initiates the flotation process. Collectors selectively coat the surface of one mineral we want to float, making it hydrophobic. The particles are more willing to attach to a bubble and float out of the bulk

Jul 20, 2021 Micro-flotation tests were carried out to study the flotation behavior of chalcopyrite and galena under different reagents scheme. As indicated in Figure 4 , in the absence of any depressant, both chalcopyrite and galena were floatable with high recoveries of more than 90% over the pH range from 3 to 10 using potassium butyl xanthate (KBX) as

Cassiterite is the most common and important tin-bearing mineral, and calcite, a primary gangue mineral is generally found in tin deposit. The flotation separation of cassiterite from calcite remains a challenge due to their similar response to traditional reagents. In cassiterite flotation, sodium oleate (NaOL) and sodium silicate (SS) have been widely used as a collector and a depressant

Froth flotation is a method of separating ores using the difference in physical and chemical properties of mineral surfaces. It is currently the main method for the flotation of copper oxide. Relatively speaking, froth flotation can be used to separate malachite and azurite. However, chrysocolla and copper phosphate are difficult to float
