This thesis presents an innovative methodology referred to as the ultrasound synergistic manganese dioxide oxidizing acid leaching process, specifically designed for treating complex acid leaching residues obtained from primary zinc oxide ore. ICP-OES analysis revealed that the zinc leaching residues contain 4.57 % zinc, 55.81 % oxygen, 13.51 % calcium, 11.33 % sulfur, 4.39 % iron, 3.23 % silicon, and 0.62 % lead. Optimal operational parameters were determined through a one-factor experimental design under ultrasonication, which included a manganese dioxide concentration of 11.11 g/L, an initial acidity of 160 g/L, a liquid-solid ratio of 7 mL/g, ultrasonic power set at 420W, and leaching conducted at a temperature of 85°C for a duration of 30 min, achieving a zinc leaching rate of 95.68 %. Characterization studies demonstrated that the synergistic effect of ultrasonic waves and manganese dioxide not only disintegrated the mineral surfaces, opened mineral inclusions and released encapsulated zinc but also accelerated the reaction, ultimately enhancing the leaching rate of zinc.

Due to mass transfer limitations, supersaturation is often not uniformly controlled in reactive crystallization processes generating an excessive amount of fine particles, which often tend to agglomerate causing issues in downstream operations, such as filtration and drying. We demonstrate rapid microwave-assisted temperature cycling (RMWTC) as a post-treatment approach that can effectively address these problems. Specifically, we report that in the event of high solids load systems, RMWTC intensifies fines dissolution during rapid heating and promotes faster recrystallization on surviving surfaces during rapid cooling. The RMWTC approach facilitates tuning not only of particle size, but possibly of crystal morphology by increasing the number of stable agglomerates with a positive concomitant impact on particle filterability and process time. A thermal parametric study on an aromatic amine API intermediate system revealed that there is an optimal temperature operating window (60 °C-105 °C) that shifts particle size distribution (PSD) towards larger particle sizes and yields up to 82 % improved filterability at 50 % less process time compared to the traditional particle control strategy, currently applied in industry for this process.</div></div>","PeriodicalId":9929,"journal":{"name":"Chemical Engineering and Processing - Process Intensification","volume":"211 ","pages":"Article 110241"},"PeriodicalIF":3.8,"publicationDate":"2025-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143549770","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ultrasonic treatment of Newtonian emulsions at the power and exposure time parameters studied had a slight effect on water separation and resulted in an increase in viscosity, indicating the ineffectiveness of ultrasonic demulsification of these emulsions. In the case of non-Newtonian emulsions, an intensification of the demulsification process reached 46–61 %. The most effective water separation from all emulsions was observed with the ultrasonic treatment at a power of 0.2 kW after 2 min. However, the demulsification and emulsification processes occur simultaneously in emulsions treated with ultrasound.
