The Al–Si alloy can extract the metallic magnesium from the serpentine at 10–20 Pa of vacuum and from 1100 to 1200 °C. In the process of magnesium extraction, at the same time these nickel-iron alloy and dicalcium silicate and aluminum silicate slag used as raw materials for the preparation of cement can be obtained. 2.

The effects of magnetite as the magnetic seed on magnetic coating behavior in pentlandite and serpentine system were investigated through magnetic separation tests, X-ray diffraction analysis, zeta potential measurements, and calculations of DLVO (Derjaguin–Landau–Verwey–Overbeek) theory. The results show that, the …

As a result, pentlandite particles were coated by magnetite fines and surface magnetism of pentlandite was enhanced to enable its separation from serpentine by the magnetic separation method. 4 Conclusions 1) Pentlandite could be separated from serpentine at pH 8.8 and a magnetic intensity of 200 kA/m, and by adding 5% …

It combines all essential project management capabilities into a single easy-to-use system: account management, business development, traffic management, project management, project finances, time tracking, billing, HR management and resource …

It is clear that in relating D and K of retro- grade serpentinites to the serpentimzation process. the role of Fe-bearing serpentine-group minerals cannot be ignored. Changes in magnetic suscept- ibility during prograde metamorphism of serpentinites also may depend on partitioning of iron between Fe-bearing serpentines …

Based on the line current approximation, a semi-analytical method for 3D magnetic field computation of the serpentine quadrupole coil is presented. Using the Biot-Savart law, the integral field of a line current with finite length located at an arbitrary position is derived. By dividing the coil into many line current segments, and summing up the …

Here we present the first geophysical characterization of serpentinite carbonation across scales ranging from km to sub-mm by combining aeromagnetic …

A. Integral Field of a Straight Line Current Firstly, the magnetic field generated by a unit conductor ele-ment parallel to the axis is considered. The conductor element is located at an arbitrary ...

The microprobe analysis showed that the minerals serpentine and cronstedtite constitute the main nickel carriers in the "Kastoria" ore. More specifically, the NiO content in serpentine ranges from 0.98% to 6.38%, with a mean value from 20 analyses of 3.44%. The NiO content in cronstedtite ranges from 2.78% to 11.5%, …

In general, magnetic fields emanate from the current loops and coils with a fixed spatial shape (dipolar at large distances). All current fusion experiments, and also …

From Fig. 4, it is very obvious that the pentlandite had a higher recovery to the magnetic fraction than the serpentine mineral with or without the addition of magnetite.To maintain the same recovery, the required magnetic field intensity changed significantly with increasing amounts of magnetite. For example, to achieve a pentlandite recovery of 85% …

Serpentinization is a geological low-temperature metamorphic process involving heat and water in which low-silica mafic and ultramafic rocks are oxidized, anaerobic oxidation of Fe2+ by the protons of water leading to the formation of H2) and hydrolyzed with water into serpentinite. Peridotite, including dunite, at and near the seafloor and in ...

Variably serpentinized peridotites from the Zedang ophiolite in southern Tibet were magnetically and petrologically examined to …

In this paper, a dry particle-particle coating technique was implemented to develop magnetic adsorbent from natural mineral constituents. Iron ore, specifically banded iron formation (BIF), was used as guest magnetic particles while serpentine (Serp) was used as host adsorptive material. Surface characterizations for the synthesized …

Our Direct Wind process naturally integrates prestress into the coil structure so external coil collars and yokes are not needed; the final coil package transverse size can then be very compact. Direct Wind magnets are produced with very good field quality via corrections applied during the course of coil winding.

The darker the grains, the more magnetic they are. The wedge-shaped grain on the left that is significantly darker in the upper corner is an especially good example. It flips its darker side towards the hand magnet if the magnet is slowly moved towards the grain. The width of the view is 17 mm. Magnesite (white) and serpentine from Norway.
