Abstract
One or more surfactants and one or more adjuvant gases in the hydrometallurgical and pyrometallurgical processes, which are added thereto in the state of nanobubbles and microbubbles, both the gases used and the nanobubbles and the microbubbles thereof, are in a variable proportion depending on the physicochemical requirements of each of the stages of the process where it is applied. The nanobubbles and microbubbles, of the proposed composition, make it possible to significantly increase the physicochemical properties of these gases such as: flotation speed, oxidizing power, reducing power, contact area provided and coalescence speed.
