description: This work is devoted to the search for the most universal and effective technology for recycling tungsten-containing solid alloy industry waste. During the study, the following tasks were solved: 1. Studying the literature with the compilation of a classification of tungsten- containing waste of modern industry with a detailed consideration of its processing technologies for extracting the maximum amount of valuable components. 2. Identification of peculiarities of tungsten-containing wastes of hard alloy industry and analysis of technologies suitable for their complex processing (on the basis of conducted study of literature data). 3. Selection and justification of the most universal technology of complex processingÂ  ofÂ  variousÂ  classesÂ  ofÂ  tungsten-containingÂ  wastesÂ  ofÂ  theÂ  hardÂ  alloy industry. 4. Technical description of the technology recommended for the complex processingÂ  ofÂ  variousÂ  classesÂ  ofÂ  tungsten-containingÂ  wastesÂ  ofÂ  theÂ  hardÂ  alloy industry: sequence of operations, chemical processes and instrumentation. Â  Â  Modern technologies for processing tungsten-containing wastes of the hard alloyÂ  industryÂ  wereÂ  comparedÂ  inÂ  termsÂ  ofÂ  theirÂ  versatility,Â  productivity, complexity, environmental friendliness, and energy efficiency. It has been shown that according to the combination of criteria, one of the most effective methods is the fusion of tungsten-containing waste with sodium nitrate. Â  Â  BasedÂ  onÂ  theÂ  resultsÂ  ofÂ  analysisÂ  basedÂ  onÂ  theÂ  methodÂ  ofÂ  alloyingÂ  with sodiumÂ  nitrate,Â  aÂ  basicÂ  technologicalÂ  andÂ  apparatusÂ  schemeÂ  ofÂ  aÂ  universal technologyÂ  forÂ  complexÂ  processingÂ  ofÂ  theÂ  widestÂ  classÂ  ofÂ  tungsten-containing wastes of the sodium hard alloy industry is proposed.
