The recovery of fine iron minerals from quartz and

The separation of hematite from corundum was achieved by using a dispersant such as sodium hexa metaphosphate. Microscopic, XRD and FTIR studies strongly suggested the coating of magnetite on hematite surfaces. Experiments were also conducted with hematite, corundum and quartz mixture to simulate the condition of Indian iron ore slimes.

Spearating Look-alike Gems gemstonemagnetism

Separating look-alike gems with a magnet. Chrome Tourmaline and Verdelite Tourmaline can look similar, but Chrome Tourmaline (a Dravite species) is rarer and more valuable. The two are easily separated with a magnet. The deep green color of Chrome Tourmaline is due to small amounts of chromium and/or vanadium, and it is usually inert (diamagnetic) when floated, or occasionally very

Eriez Dynamic Drum Separators

The non-magnetic fine powder does not react with the magnetic field and falls away from the head pulley in a normal trajectory. A strategically placed splitter enables separation of the iron from the non magnetic powder. The success of the DDS is attributed to the unique Eriez Dynamic Agitation Effect. This greatly improves magnetics recovery

WO2003035574A1 A chrome-aluminum spinel refractory

A chrome-aluminum spinel refractory material comprises 20-98wt% corundum and 2-80wt%wt chrome iron ore. A binder also added to the said refractory material in an amount 0.5-14wt%, based on total weight of corundum and chrome iron ore. The properties of the resulting refectory material are improved by adding chrome iron ore.

Separation of the impurity and lattice components of the

The impurity and lattice contributions to the spin-lattice relaxation of Al27 nuclei in nominally pure and lightly chromium-doped corundum (Al2O3) crystals are separated experimentally under the conditions of additional stationary resonance magnetic saturation of a pulsed NMR signal. The relaxation time T i lat due to the lattice mechanism of the spin-phonon interaction is determined.

10 Practical Uses for Gem Identification

3) Gems with a High Refractive Index: Some gems can't be separated by refractive index because readings are OTL (over the limit of the refractometer fluid, R.I. >1.81). However, we can sometimes rely on differences in magnetic response to separate one type of OTL gem from another. For example, natural red Zircon may look very much like red Spessartine Garnet, and Demantoid Garnet may look
