Publication number: 20230220514Abstract: A plurality of different metals, including precious metals, platinum group metals, rare earth elements, alkaline earth metals, etc., can be electrochemically recovered from waste materials such as ashes and e-waste, e.g., printed circuit boards. Waste feed stocks are treated with supercritical CO2 (scCO2) and acid to produce a solid delaminated waste and a liquid delaminated waste for recovery of elemental metals and metal compounds from each. Carbonation reactions can be used to convert and recover alkaline earth metals from the liquid delaminated waste. The solid delaminated waste can yield a solid gold product, and be further treated along with the liquid delaminated waste via a solvent including one or more organic ligands that bind target metals to form metal-ligand complexes. Electrochemical separation of the different metals, e.g., via stepwise variation of pH to release the metals from organic ligands having different pKa values, yields high purity metal product streams.Type: ApplicationFiled: January 9, 2023Publication date: July 13, 2023Inventors: Ah-Hyung Alissa PARK, Peng PENG, Haonan Danny HUANG

Publication number: 20220127151Abstract: A method and system for producing highly activated silicate material, wherein the silicate source material is provided for reaction with a reforming agent in a reforming process. The reforming process is a hydrothermal process and/or a high temperature silicate reforming (HTSR) process. A heat source heats reaction materials to a reaction temperature in the presence of a reaction medium. For the hydrothermal reaction process, the reaction medium and heat source are an exhausted steam that is a byproduct of another industrial process. For the HTSR process, the silicate source material and the heat source are a molten slag byproduct from another industrial process.Type: ApplicationFiled: November 24, 2021Publication date: April 28, 2022Applicant: THE TRUSTEES OF COLUMBIA UNIVERSITY IN THE CITY OF NEW YORKInventors: Ah-Hyung Alissa PARK, Xiaozhou ZHOU, Chengchuan ZHOU

Patent number: 11242261Abstract: Methods and systems for producing activated silicate materials are disclosed. A silicate source material is provided for reaction with a reforming agent in a reforming process. The reforming process is a hydrothermal process and/or a high temperature silicate reforming (HTSR) process. The reaction materials are brought to the suitable reaction temperature via a heat source in the presence of the suitable reaction medium. The activated silicate materials exhibit improved reactivity compared to non-activated silicate materials and thus are advantageously employed in elemental extraction processes to produce a valuable material product.Type: GrantFiled: September 19, 2017Date of Patent: February 8, 2022Inventors: Ah-Hyung Alissa Park, Xiaozhou Zhou, Chengchuan Zhou

Patent number: 11162158Abstract: Systems and methods for processing slag produced by iron and steel making processes are disclosed. The slag is treated produce a series of valued industrial products, such as metal oxides, metal carbonates, rare-earth metals, and water glass. The systems and methods also integrate slag processing with CO2 sequestration and flue gas desulphurization. Processing slag minimizes the land use for stockpiling or landfilling wastes produced from iron and steel making processes and protects the ground water underneath. Overall, the solid and gaseous emissions of an energy-intensive and highly polluted industrial process have been largely reduced, recycled and valorized in order to achieve a near zero-emission goal.Type: GrantFiled: September 19, 2016Date of Patent: November 2, 2021Inventors: Ah-Hyung Alissa Park, Xiaozhou Zhou
