The majority of research on rheology in mineral processing has been focused on ore grinding. Shi and Napier-Munn (2002) have analysed the data of 45 surveys from full scale grinding mills, using regression analysis, and shown that slurry rheology affects industrial grinding. The results of the Shi and Napier-Munn (2002) has also …

The processing plants have followed suit with large 42 ft diameter mills, 500–700 m 3 flotation cells along with larger dewatering and tailings pond facilities. The trend of increasing throughput and larger equipment is continuing despite all associated challenges along with an on-going trend of extremely high waste generation.

The volume of a flotation cell depends on the volumetric flow rate and the retention time. Vf=(Q Tr S)/(Ca) Vf = volume of tank, Q = volumetric flowrate, Tr = retention time. Retention time is defined by the kinetics of flotation, which means it is determined from test work. Some correction factors can be included:

1. Introduction. Froth flotation was commercially introduced early in the 20th century. Now, almost 100 years later, it is the most important and widely used separating method for minerals.In its application to mineral flotation, the ore is first ground in water to a certain size to produce a suspension which is then subjected to vigorous mixing in a …

Flotation is a common mineral processing method used to upgrade copper sulfide ores; in this method, copper sulfide mineral particles are concentrated in froth, and associated gangue minerals are separated as tailings. However, a significant amount of copper is lost into tailings during the processing; therefore, tailings can be considered …
