Mineral Separation - NMSU Geological Sciences

The final step in mineral separation is by preferential flotation of mineral fractions by heavy liquid. Nonmagnetic fractions first undergo separation by sodium polytungstate (SPT; 2.85 g/cm3) and finally by methylene iodide (MEI; 3.3 g/cm3). At the end of separation, the final fraction should contain minerals such as zircon, apatite, monazite ...

Selective adsorption of a novel X-shaped surfactant ...

In mineral flotation, the effective separation was mainly accomplished by the selective adsorption of surfactant on mineral surface. In this section, we adopted DFT calculation, surface property, and molecular structure analyses aimed to provide a comprehensive explanation for the selectivity of DODHA.

Comminution and Mineral Separation—Geological Input

This requirement is examined here, albeit for only two of the three metallurgical ore-processing activities—comminution and mineral separation. Wealth is not captured (i.e., is destroyed) unless the most efficient and effective methods for comminuting and separating the mineral (s) of value in a deposit are identified.
