Mining

 


High-purity magnesium oxide has moderate chemical activity and ensures fast depletion of precious metals from the mined ores, such as cobalt, nickel and copper from acid leach solutions. Using synthetic magnesium oxide ensures high production capacity in hydrometallurgy compared with mined magnesium products of natural origin having a lower frequency and a slow and nonuniform chemical activity.

Magnesium oxide is used as a component of the cementing compound for making air-tight seals when drilling wells. After magnesium oxide is added to cementing compound it is hydrated and expanded ensuring stable bond between soil and casing.

Magnesium oxide can also be used as a thickening agent in drilling muds. Drilling muds are complex mixtures with a lot of additives which can change fluid density, rheology and pH level. Magnesia (magnesium oxide) is used in drilling muds where it acts as a detergent to maintain the purity of annulus and neutralize acid gases released during the drilling.

Magnesium chloride is used in oil extraction as a part of special drilling muds applied to repair and suspend oil wells and as a main component of magnesia cement slurries used during construction of oil and gas wells.

Magnesium chloride is used for cargo transportation of ore materials, coal and any other congeal bulk materials as an anti-congealing agent. Mechanism of magnesium chloride action refers to moisture adsorption from air and reduction of free moisture content in particles that prevents forming solid agglomerates.
