Publication number: 20230227937Abstract: The present disclosure provides a method for extracting lithium using a resin adsorbent to pretreat low-grade deep brine, which relates to the technical field of lithium extraction from brine. In the present disclosure, resin adsorbent is used to perform adsorption pretreatment on the concentrated brine, which can adsorb organic impurities in the concentrated brine without adsorbing lithium ions, so that the concentration of lithium ions is almost unchanged compared with the feed material, with the subsequent manganese-based lithium adsorbent, the adsorption rate of lithium can be increased by 41%; At the same time, pretreating the concentrated brine using resin adsorbents has shorter steps, less materials, and does not produce a large amount of low-value product gypsum, which makes the lithium extraction process simpler and easier to operate, and reduces production costs.Type: ApplicationFiled: January 14, 2022Publication date: July 20, 2023Applicant: Qinghai Geological and Mineral Testing Center (Qinghai Province Eco-environmental Geology InspectionInventors: Yuqing Zhao, Yongpeng Ying, Xin Xiong, Hongshu Fang, He Jiao, Liping Wu, Fang Jin, Dao Liu, Haiming Li

Publication number: 20230197105Abstract: Various methods, apparatuses/systems, and media for automatic real-time identification of dissatisfaction data are disclosed. A receiver receives real-time stream of call transcript data generated during a call or a chat between a customer and an agent. A processor implements a machine learning model that includes predefined complaint data; applies the received call transcript data onto the machine learning model; compares, in response to applying, the call transcript data with predefined complaint data; generates a first similarity score, based on comparing, that identifies how similar the call transcript data is compared to the predefined complaint data; and automatically identifies the call transcript data as a first dissatisfaction data based on determining that the first similarity score is equal to or more than a predetermined threshold value.Type: ApplicationFiled: November 22, 2022Publication date: June 22, 2023Applicant: JPMorgan Chase Bank, N.A.Inventors: Siva TANUKU, Matthew RAY, Rachel BRINDA, Liping WU, Tiffany WAGNER, Bhavya POTLURI, Khyati SINHA, Serdar KUYUK, Anand P.
