Bubble sizes that are discussed in the flotation area of current literature are usually in four size groups. The typical bubble size in conventional flotation machines is found to be in the range close to 1 mm, such as the data reported by several researchers which were 600–2500 μm (Rodrigues et al., 2007), 800–1600 μm (Shao, 2004), and …

Froth flotation is widely used for concentration of base metal sulphide minerals in complex ores. One of the major challenges faced by flotation of these ores is the ever varying grade and mineralogy. This therefore calls for a continual characterisation and optimisation of flotation parameters such that concentrator performance as a whole is always …

This explains why, in order to smelt 4 million tons of new copper in 1963, nearly 400 million tons of ore had to be handled and treated in various ways. Flotation depends on the fact that the grains of some minerals, and especially of metals, differ in the degree to which their surfaces can be wetted by a suitable solution.

The demand for copper is ever-increasing, playing a critical role in the transition to a clean-energy economy. By the early 21st century, most of the rich copper oxide ores had already been mined out, leaving current deposits with a grade sometimes less than the tailings of earlier mining [1,2].A study conducted by Calvo et al.
