RESEARCH ON TECHNOLOGICAL METHODS AND EFFICIENCY OF DEEP ENRICHMENT OF TUNGSTEN FROM TECHNOGENIC WASTE

Main Article Content
Abstract
The technology of extracting tungsten from technogenic waste is complex due to the presence of impurities such as iron, bismuth, and other minerals, which complicate the beneficiation process. This article explores the efficiency of the deep flotation method for tungsten extraction from technogenic waste. Research findings indicate that deep flotation is inefficient from both a technological and economic perspective. Challenges arose in selectively separating impurities during flotation, resulting in a lower-than-expected yield of tungsten. Therefore, the article suggests an alternative approach—a combination of gravity and flotation methods. This combined approach allows for effective management of impurities in technogenic waste, achieving high tungsten extraction efficiency and ensuring the environmental safety of the process.
