摘要： A metallurgical process for a tungsten mineral raw material (100), comprising: employing a weak base leaching agent conducive to forming a local process circulation, the leaching agent generating two or more gases in an evaporative crystallization process, each kind of gas being able to participate again in the synthesis of the leaching agent, and a crystallized separation scrubbing solution being similarly recycled as a leaching agent; and employing a transformation ingredient, the transformation ingredient having a chemical reaction with the tungsten mineral raw material (100) to enable tungsten element to be comprised in an intermediate easily dissolved by the leaching agent, and a leaching residue also comprising an ingredient element, such that at least a part of the leaching residue can be recycled as the ingredient. The process comprises a plurality of closed cycles, and produces no wastewater discharge in the entire process.

摘要： The invention relates to a process for recovering Group VIB metals from a catalyst, in particular a spent bulk catalyst, comprising one or more Group VIB metals and one or more Group VIII metals. Further, the invention relates to a solid Group VIB metal compound obtainable by the process according to the invention having the general formula H 2 XO 4 , wherein X = W 1-y Mo y , wherein y is between 0 and 1 and to its use in a process for the manufacture of a fresh catalyst. The process comprises the steps of: a) oxidizing the one or more Group VIB metals to one or more Group VIB metal oxides; separating the one or more Group VIB metal oxides from the one or more Group VIII metals; dissolving the one or more Group VIB metal oxides in water to produce an aqueous solution of one or more Group VIB metal oxides; d) precipitating the one or more Group VIB metal oxides from the aqueous solution by adding alkaline earth metal (Group IIa) ions to the aqueous solution; e) optionally filtering and washing the precipitate; and f) transforming the precipitate by adding an acid to form a solid metal compound comprising one or more Group VIB metals.
