Green Flotation Depressants

Depression is used to increase the selectivity of flotation by rendering certain minerals hydrophilic, thus preventing their flotation. They are key to the economic flotation of many ores. They are generally classed as inorganics, small organics, and organic polymers. The use of polymeric depressants has the attraction of being less hazardous than the more widely used inorganic depressants, such as cyanide, which are widely used in sulphide systems. 

Biodegradable depressants are becoming more important due to environmental concerns and the need for environmentally friendly processes. They can replace or assist inorganic and toxic reagents in various flotation conditions.

Green Flotation Depressants, authored by Saeed Chehreh Chelgani et al, is a new publication on biodegradable depressants, delving deep into their performance, intricate structures, and adsorption mechanisms. The book describes diverse minerals and materials where these depressants have been used for their upgrading. Encompassing the entirety of current research, it is aimed at industry professionals and researchers in the field, especially on courses centered around froth flotation and recycling. From starch-based solutions to the diverse array of gums and the intriguing polyaspartate and tripolyphosphates each section unfolds a rich tapestry of knowledge, providing a holistic understanding of biodegradable depressants and their pivotal role in mineral processing.
