Abstract

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.

IPC Classes  ?

• C01F 5/14 - Magnesium hydroxide
• B01D 53/62 - Carbon oxides

Abstract

Described herein is a soda magcite composition, methods of manufacture of soda magcite compositions and use of soda magcite for carbon dioxide sequestration. The soda magcite composition comprises a mixture of magnesium hydroxide, metal hydroxide and water to create a composition that is highly effective at sequestering carbon dioxide.
