Patent number: 11898220Abstract: A method for recovery of platinum group metals from a spent catalyst is described. The method includes crushing the spent catalyst to obtain a catalyst particulate material including particles having a predetermined grain size. The method includes subjecting the catalyst particulate material to a chlorinating treatment in the reaction zone at a predetermined temperature for a predetermined time period by putting the catalyst particulate material in contact with the chlorine containing gas. The method also includes applying an electromagnetic field to the chlorine-containing gas in the reaction zone to provide ionization of chlorine; thereby to cause a chemical reaction between platinum group metals and chlorine ions and provide a volatile platinum group metal-containing chloride product in the reaction zone. Following this, the volatile platinum group metal-containing chloride product is cooled to convert the product into solid phase platinum group metal-containing materials.Type: GrantFiled: October 3, 2019Date of Patent: February 13, 2024Assignee: YEDA RESEARCH AND DEVELOPMENT CO. LTD.Inventors: Igor Lubomirsky, Valery Kaplan

Patent number: 11718893Abstract: A method for recovery of gold from gold-containing materials, such as electronic waste material, minerals and sands is described. The method includes crushing the gold containing material to obtain a particulate material. The particulate material is then preheated in an oxygen-containing gas environment in a preheating zone. The method also includes mixing the oxidized particulate material with a chlorine-containing material and treating the mixture in a reaction zone. The treatment is carried out by heating the mixture to provide thermal decomposition of the chlorine-containing material and produce a chlorine-containing gas mixture, and by applying an electromagnetic field to the chlorine-containing gas mixture to provide ionization of chlorine. A volatile gold-containing chloride product, produced in the reaction zone as a result of a chemical reaction between gold and chlorine ions, is then cooled to convert the volatile gold-containing chloride product into solid phase gold-containing materials.Type: GrantFiled: November 1, 2018Date of Patent: August 8, 2023Assignee: YEDA RESEARCH AND DEVELOPMENT CO. LTD.Inventors: Igor Lubomirsky, Valery Kaplan, Nurlan Dosmukhamedov, Erzhan Zholdasbay
