Concentrate magnetic

The systems undergoing phase transitions (like spinodal decomposition) often exhibit scaling phenomena [ 1—4] that is, a morphological pattern of the domains at earlier times looks statistically similar to a pattern at later times apart from the global change of scale implied by the growth of L(f)—the domain size. Quantitatively it means, for example, that the correlation function of the order parameter (density, concentration, magnetization, etc.)... 

There are three main methods used for beneficiation of tin ores (a) physical concentration including gravity concentration, magnetic separation and electrostatic separation (b) flotation and (c) a combination of gravity preconcentration and flotation. 

There are many parameters could affect the pitch of N -LCs, such as ionic strength, drying temperature, suspension concentration, magnetic field [22] and sonication [23, 24]. Interestingly, the chiral nematic orders can be retained after evaporation of the...

Thorium is produced commercially from monazite sands. After mining, the monazite sands are concentrated magnetically and then treated with either hot, concentrated sulfuric acid or hot, concentrated sodium hydroxide. The... 

These types of magnetic fluids, owing to the strongly polar character of the carrier, have several particularities concerning their preparation procedures, as well as their colloidal stability and physical properties. The doublelayer electrostatic stabilization mechanism [9] gives weakly stable and relatively low concentration magnetic fluids, which manifest phase-separation (droplike... 

Equation (1) may be extended in the framework of the same TFT for concentrated magnetic fluids, applying the second-order approximation [20] ... 

Bismuth concentrates are almost always obtained as by-products from metallic ores containing bismuthinite, bismite, and native bismuth in their gravity concentration, magnetic separation and floatation. Or from the further collection of bismuth-containing materials produced on the metal smelting process, they mainly exist with the phases of sulfide and oxide. The traditional extraction processes on the bismuth concentrates are classified as pyrometallurgy and hydrometallurgy smelt. It will be reviewed as follows.
