Inhibiting or preventing corrosion of metallic components downhole may be accomplished by introducing neutralization media into a wellbore in the proximity of downhole metallic components, where the neutralization media comprises magnesium and where the method further includes subsequently contacting the neutralization media with a potentially corrosive environment comprising at least 5 volume % water, where the water has a pH of less than 11. This contacting activates the neutralization media with the water thereby releasing magnesium ions, and the magnesium ions react with hydroxyl ions of the water to give magnesium hydroxide in an amount effective to raise the pH of the water present to be between about 8 and 12 thereby inhibiting or preventing corrosion of metallic components downhole.

The present invention relates to an aqueous magnesium hydroxide suspension comprising: a) at least 40 wt. %, relative to the total weight of the suspension, of magnesium hydroxide particles; b) from 0.001 to 5 wt. % relative to the total weight of the magnesium hydroxide of at least one dispersant and c) from 0.001 to 5 wt. %, relative to the total weight of the suspension, of at least one anti-foaming agent. The present invention further relates to the use of this aqueous suspension for the treatment of gas washing water in an on-board wet or semi-wet flue gas desulfurization system, the treatment of effluent at a municipal or industrial wastewater treatment plant, in industrial transformation processes or bioprocesses involving a fermentation or respiration process, or in the paper production process or in agriculture.

Methods of processing magnesium silicate materials are described to produce a number of products including magnesium hydroxide. Related methods of use of processed magnesium silicate and other reaction products are described for energy production, cement manufacture and carbon sequestration. In one embodiment the method comprises subjecting a magnesium silicate source to an acid digestion; increasing the digested liquid pH to produce a magnesium salt solution; subjecting the magnesium salt solution to electrolysis; and recovering magnesium hydroxide produced from electrolysis. By-products such as silica, iron oxy(oxides) and others are also described along with further reaction products such as magnesium oxide and magnesium carbonate.
