AI Technical Summary

Benefits of technology

The present method involves treating spent sulfur-containing liquids from various industries such as crop production processes where nitrogen fertilizers were commonly applied during cultivating crops for better yields. By adding certain substances like sucrose (sugar) syrupyitol solution), it becomes possible to recover valuable compounds called glucosamine which could have beneficial uses in medicine or other fields. Additionally, this treatment reduces harmful chemical pollution caused by excessive disposal of sour water containing ammonia gas generated when managing acid rain. Overall, these technical results lead to improved economic efficiency while minimizing negative impact on environmentally friendly practice.

Problems solved by technology

Technologies described involve different methods or techniques related to producing magnesium oxide nanoparticles called nanofermorsicles. These particles consists mostly of Fe(II)-Pyrochlorum). By adding specific chemical agents like calcium chloride, ammonium nitrate, citric acid, sodium carbonate, etc., they become solublized together inside these materials until reaching their desired size. After filtrating away any impurity found within the resulting mixture, the remaining part becomes coarse salt again while another portion remains intact.

Abstract

A gray manganese ore leaching-out process is carried out by crushing, blending with water to obtain ore pulp, adding into sulfuric acid and sugar honey alcohol effluent, agitating at 50-98degree and reacting for 0.5-4hrs to obtain the final product. The leaching-out rate of manganese is >93%. It's simple, has gentle reactive condition and no environmental pollution.
