Title: Ray D. Peterson: Innovator in Aluminum Recycling and Lithium Extraction

Introduction

Ray D. Peterson is a notable inventor based in Florence, Alabama, with a significant contribution to the field of materials recycling. He holds five patents that showcase his innovative approaches to improving processes related to aluminum beverage cans and lithium extraction from aluminum-lithium alloys. His work has implications for both environmental sustainability and resource recovery.

Latest Patents

One of Peterson's latest patents is focused on the separation of free lead from aluminum beverage cans. This method involves shredding used aluminum beverage cans, heating them to a temperature above the lead melting point, and agitating the material to fragment the molten lead into small particles. The process then screens the material to create two particle streams: one containing a high percentage of free lead and the other primarily consisting of shredded aluminum beverage cans. The lead-rich stream is further processed in a fluidized bed to separate fines from aluminum particles, allowing for the recovery of aluminum for reprocessing.

Another significant patent by Peterson is a method for extracting lithium from aluminum-lithium alloys. This improved technique utilizes an electrorefining cell with a cathode made of pure molten tin. By applying an electric current, lithium dissolves from the molten aluminum-lithium alloy into the tin pool, forming a tin-lithium alloy. This alloy can be recovered and further processed to extract lithium through various methods, including electrolytic recovery and vacuum distillation.
