In conclusion, the sulfur wastes obtained from chemical and thermal methods for sulfur purification in the Mashreq field has been present for decades in significant quantities, approaching two million tons, with its harmful impact on the environment. Our research focused on using a different approach by utilizing the acidic sulfur wastes (foam) as a ...

Preparation of nano sulfur from the wastes (foam) in the Al_Mishraq sulfur mine (Mosul/Iraq)
The research included estimating the elemental sulfur percentage in sulfuric foam waste, which was found to be 88.15%. Potassium polysulfide was prepared from this waste and used to prepare nano-sized sulfur particles through reduction processes. Stable suspensions were obtained for more than 30 days.
