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.

The steel industry accounts for about 7%‐9% of global CO2 emissions. While H2‐based direct reduction is a long‐term route, near‐term solutions are needed for existing plants. Internal carbon cycles reuse steelworks off‐gases and by‐products, enabling circular carbon use and supporting CCU integration.

Peroxodisulfate‐Enhanced Leaching of Deep‐Sea Manganese Crusts and Sulfides
Ammonium peroxodisulfate enables efficient leaching of deep‐sea manganese crusts and massive sulfides while offering electrolytic recycling. High leaching yields for V, Mn, Co, Mo, Sn, and W, along with complete leaching of As and Sb, highlight its potential as a powerful and sustainable oxidant for marine resource processing.
