Abstract: The present description relates to a process for extracting magnesium compounds from magnesium-bearing ores comprising leaching serpentine tailing with dilute HCl to dissolve the magnesium and other elements like iron and nickel. The resudial silica is removed and the rich solution is further neutralized to eliminate impurities and recover nickel. Magnesium chloride is transformed in magnesium sulfate and hydrochloric acid by reaction with sulfuric acid. The magnesium sulfate can be further decomposed in magnesium oxyde and sulphur dioxyde by calcination. The sulphur gas can further be converted into sulfuric acid.

Abstract: The disclosed processes can be effective for treating various materials comprising several different metals. These materials can be leached with HCl for obtaining a leachate and a solid. Then, they can be separated from one another and a first metal can be isolated from the leachate. Then, a second metal can further be isolated from the leachate. The first and second metals can each be substantially selectively isolated from the leachate. This can be done by controlling the temperature of the leachate, adjusting pH, further reacting the leachate with HCl, etc. The metals that can be recovered in the form of metal chlorides can eventually be converted into the corresponding metal oxides, thereby allowing for recovering HCl. The various metals can be chosen from aluminum, iron, zinc, copper, gold, silver, molybdenum, cobalt, magnesium, lithium, manganese, nickel, palladium, platinum, thorium, phosphorus, uranium, titanium, rare earth element and rare metals.

Abstract: The present invention teaches the method to use the sulfate or sulfites based raw materials, such as magnesium, calcium and other alkative earth sulfates or sulfites to produce the respective oxides in a carbon five basis, by using sulfur as the fuel and the reductant. The invention also utilizes renewable energy such as solar thermal or green electricity wherever possible. This approach provides a green process, of ultra-low carbon dioxide emission, for the production of magnesium, other alkaline earth metals and other material which requires alkaline earth oxide, such as in the production of carbon free Portland cement requiring lime. The invention also provides a useful outlet for waste streams leading to sustainable processes. The cost of the production of these precursors are kept low by concurrently producing a saleable by-product—sulfuric-acid.
