This Small Business Innovation Research Phase II (SBIR) project will develop and demonstrate a novel prototype solvent extraction (SX) device, which, by virtue of its highly uniform shear and mixing intensity, has the potential to supplant existing SX units in terms of extraction and phase separation rates. The technical approach of the Phase II project is as follows: 1.) Develop performance and scale-up principles for the SX device, optimize the hardware configuration and process conditions; 2.) Apply the results to the design of a reliable prototype SX system that demonstrates improved mass transfer and phase separation, and decreased entrainment at power consumption levels equivalent to existing equipment. The Phase I copper extraction work showed a 3-5 fold improvement in extraction and phase separation rates over existing mixer-settlers that are used in the minerals industry for the recovery of copper. The commercial benefits of the ResonantSonic solvent extraction device to the minerals industry are reduced equipment size and footprint, reduced solvent loss, and improved electrowinning efficiency. Reducing the solvent loss to the environment has great societal benefit as losses can exceed 100,000 gallons per year per mine site. Other potential applications are metals separation, and the recovery of vitamins, antibiotics, and other pharmaceuticals

这个小型企业创新研究二期（SBIR）项目将开发并演示一种新型溶剂萃取（SX）装置的原型，该装置由于其高度均匀的剪切和混合强度，在萃取和相分离速率方面有可能取代现有的SX装置。二期工程的技术思路如下：制定SX设备的性能和放大原则，优化硬件配置和工艺条件；2)。将结果应用于可靠的原型SX系统的设计，该系统可以改善传质和相分离，并在与现有设备相当的功耗水平下减少夹带。第一阶段的铜萃取工作表明，与矿物工业中用于回收铜的现有混合沉降器相比，萃取和相分离速度提高了3-5倍。对于矿物行业来说，ResonantSonic溶剂萃取设备的商业效益是减少了设备尺寸和占地面积，减少了溶剂损失，提高了电积效率。减少溶剂对环境的损失具有巨大的社会效益，因为每个矿场每年的损失可超过10万加仑。其他潜在的应用包括金属分离、维生素、抗生素和其他药物的回收
