Tiivistelmä
Mines are known to use a lot of energy for crushing and grinding the ore to a desired size. With the rising price of sustainable energy, the industry is starting to find some applications to help tackle that problem. One of those applications is the FID which under development in Metso.
The FID is a coarse particle flotation cell that uses an already made froth bed to produce concentrate. This cell could help lower the energy consumption of a plant by reducing the amount material needed to grind by floating the wanted minerals before the secondary grinding or increase the overall recovery by scavenging the coarser particles, not recoverable by standard flotation.
The froth plays a crucial role in the recovery of those particles therefore the frother must be the most optimal for the application. This research is aims to determine the optimal frother for the cell and evaluate the differences between the frothers.
