Tungsten mineral raw material metallurgical process capable of realizing no pollution discharge in whole process

The invention relates to a tungsten mineral raw material metallurgical process which is characterized in that a weak alkali leaching agent (An existing leaching agent must adopt strong alkali or strong acid in the prior art) which is favorable for forming local process cycle is adopted, leachate of the leaching agent generates two or more kinds of gases in the evaporation and crystallization processes, all the gases can also be used for the synthesis of the leaching agent again, and crystallized separating and washing liquid is also taken as the leaching agent to be recycled; a transformation ingredient is adopted, tungsten elements can be contained in an intermediate substance easily dissolved by the leaching agent through chemical reaction between the transformation ingredient and a tungsten mineral raw material, and ingredient elements are also contained in leaching residues, so that at least a part of leaching residues can be taken as the ingredient to be recycled. Therefore, the metallurgical process contains multiple closed cycles and realizes no wastewater discharge in the whole process. The metallurgical process has the benefits that the wastewater pollution is eliminated; the consumption of auxiliary materials is greatly reduced, the process is simple, the operation is convenient, and the production cost is low.
