Abstract
การประดิษฐ์นี้เกี่ยวกับกระบวนการสำหรับการแยกของโคบอลต์ออกจากลิเทียมที่มีอยู่ใน ภาระบรรจุซึ่งประกอบรวมด้วยลิเทียม-ไอออนแบตเตอรีหรือผลิตภัณฑ์ที่เกี่ยวข้อง, ซึ่งประกอบ รวมด้วยขั้นตอนของ การถลุงภาระบรรจุนั้นโดยใช้เตาถลุงแบบอ่างที่ติดตั้งด้วยหัวพ่นไฟพลาสมาที่ ป้อนอากาศแบบจมอยู่ใต้สำหรับการฉีดพลาสมาแก๊สเข้าในสารหลอมเหลวนั้น; กำหนดและรักษา ศักย์รีดอกช์อ่างที่ซึ่งรีดิวซ์โคบอลต์ไปเป็นสถานะโลหะและไปอยู่ในวัฎภาคอัลลอย, และโดยสิ่งนั้น จึงออกซิไดซ์ลิทียมเป็น Li2O และไปอยู่ในวัฏภาคกากถลุง; การรินออกและการแยกวัฎภาคเหล่านั้น มันมีลักษณะเฉพาะที่ว่าดำเนินการขั้นตอนรีดักชันและการออกซิไดซ์โดยพร้อมกัน ได้ความเข้มข้น โคบอลต์ที่ต่ำอย่างเหมาะสมในกากถลุงนั้น: This invention deals with a process for the separation of cobalt from lithium contained in Load containing lithium-ion batteries or related products, including procedures for The smelting of the load was carried out by using a tub smelting furnace equipped with a plasma torch. Submerged air feed for injecting gas plasma into the molten substance; Define and maintain Redox potential, where the cobalt is reduced to the metallic state and in the alloy cycle, and by that It oxidizes lithium to Li2O and goes into the sludge cycle; The pouring out and the separation of those sectors It is unique in that it performs a reduction and an oxidizing procedure simultaneously. Get concentrated Properly low cobalt in the sludge is:
