A new technology for preparing rich titanium product,which includes microwave reduction-mineral separation-microwave leaching,was put forward on the basis of the abundant situation of titanium mineral resource in Panzhihua-Xichang zone and the advantages and disadvantages of actual productive methods on making rich titanium product.

There are still some problems in weak-acid leaching technology selection,leaching liquor preparation and leaching liquor application.

Objective: Airtight digestion/extraction system was adopted to carry out optimization of microwave-assisted extraction technique of flavonoids from Scutellaria radix.
