AI Technical Summary

Benefits of technology

This patented innovator describes an improved process called Regel Fluorination (RF). By injecting water into a reactor with special nozzles at very short intervals, there will quickly form tiny droplets due to gravity during operation. These minute droplet sizes help crush any impurity from them while still allowing enough oxygen molecules to react properly. Additionally, this new design allows for efficient recovery of valuable metals such as manganese oxides without losing their effectiveness over long periods of time. Overall, these improvements improve the overall yield and purity of recovered MgO/Mn2 O3 produced through burning processes.

Problems solved by technology

This patented describes a new type of material called magnetic iron salt that can efficiently remove sulfur from gases like burning fossils without consuming excessive amounts of water during their production. However, this material also generates harmful metallic compounds when exposed to certain types of impurity elements such as manganese oxides. These harmful metal compound residues may cause environmental concerns due to disposable landfill operations. To solve this problem, there was proposed a solution involving recovering valuable rare earth element content through separation techniques beforehand, allowing them to reuse.
