The new froth cone and outer crowder maximizes froth recovery and creates a thicker, more stable, and more productive froth. Both the cone and crowder push the froth towards the center launder. This is especially important near the end of the circuit, after all the fast floating and well-liberated particles have been reported to the launders.

The feldspar crystal lattice consists of corner-sharing AlO 4 5− and SiO 4 4− tetrahedra linked in an infinite 3D framework, which defines feldspar as tectosilicates or "framework silicates" (Fig. 6) (Skorina and Allanore, 2015). (0 0 1) and (0 1 0) surfaces are mostly exposed when feldspar is comminuted.

The detachment process can be selective and non-selective. The froth also removes unwanted gangue minerals that are unselectively transported into the froth with the water. This phase is therefore an important part of the flotation process as it further refines the concentrate produced and determines the final recovery.

The flotation process for the concentration of ores is a method by means of which one or more of the minerals in the ore (usually the valuable ones) are picked up by means of a liquid film and floated at the surface of a mass of fluid pulp. Here they are separated from the other minerals, which remain immersed in the body of the pulp. In …
