Abstract
The efficiency of separation in flotation processes heavily relies on the reagents employed. Increasing environmental concerns have recently driven the research and development efforts towards the utilization of green reagents. Biotechnological and bioprocess approaches are being investigated as potential alternatives to conventional chemical and petroleum-based reagents. This article critically reviews the performance of green reagents, specifically biosurfactants, in the coal flotation process. It emphasizes the processing of high-sulfur coal found in Indonesia in an environmentally friendly manner to meet the rising global demand. This review aims to serve as a reference for further research, addressing current challenges, and optimizing the application of biosurfactants in coal flotation processes while adhering to principles of environmental sustainability.
