Effect of Cooling Rate and Slag Modification on the

2020-7-31  Milling and froth flotation methods are quite common when dealing with slow-cooled slags. Before flotation, the slag needs to be cooled in a controlled manner. There are multiple options for this, such as natural cooling, casting mill cooling, water quenching, and slow cooling in a ladle .
