摘要： 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.

摘要： It is an object to provide a method for producing magnesium oxide by which magnesium oxide being high in purity and low in impurity content can be produced simply and efficiently from a sulfuric acid solution containing magnesium and calcium such as waste water. In the present invention, calcium is precipitated as calcium sulfate and separated by concentrating a sulfuric acid solution containing magnesium and calcium, and magnesium is precipitated as magnesium sulfate and separated by further concentrating the solution resulting from the separation of calcium. The separated magnesium sulfate is roasted together with a reductant, so that magnesium oxide and sulfur dioxide are obtained. The resulting magnesium oxide is washed to produce magnesium oxide with high purity.

摘要： The present invention provides methods of utilizing biomass materials, in which biomass materials are mixed directly with the reactants and the biomass materials while in combustion can directly heat up the reactants to the temperature required for the chemical reaction to take place. Such chemical reaction takes advantage of the heat energy, carbon element and/or silicon element that are inherently contained within biomass materials. For instance, biomass materials produce powdery or lumpy alkali metal silicates when chemically reacting with alkali metal compounds, synthesize black powder when reacting with nitrates, redox sulfates and decompose carbonates, etc. The present invention is characterized with high heat utilization, no need for external heat source, low power consumption, greatly reduced equipment costs, and the significantly simplified process.
