Description

technical field

[0001] The invention relates to the field of metallurgy. In particular, the present invention relates to methods of processing tungsten powder waste. Background technique

[0002] With the rapid development of world economy and science and technology, industries such as metallurgical machinery, petrochemical industry, automobile industry, mining, electronic information, transportation, aerospace and national defense have gradually increased the demand for tungsten products. my country's tungsten reserves rank first in the world, and it is one of the few dominant varieties in mineral products. However, with the continuous development and utilization of tungsten resources, tungsten reserves are gradually decreasing. Therefore, the recycling of waste tungsten powder not only has huge economic benefits, but also has good social and ecological benefits.

[0003] However, the current methods of dealing with tungsten powder waste still need to be improved. Conte...
