Title: The Innovative Contributions of Barry N Doyle
Introduction
Barry N Doyle is a notable inventor based in Fort, California. He has made significant contributions to the field of metallurgy, particularly in the recovery of valuable metals from sulphidic materials. With a total of 3 patents to his name, Doyle's work has implications for both environmental sustainability and resource recovery.
Latest Patents
Doyle's latest patents include innovative processes for the recovery of metals from sulphidic materials. One of his key inventions is a method for recovering zinc and iron from zinc- and iron-containing sulphidic material, which also contains lead and silver. This process involves leaching the sulphidic material under oxidizing conditions in a two-stage countercurrent pressure leach. The result is a zinc-containing solution from which zinc can be recovered through conventional means such as electrowinning. Additionally, the process produces a lead- and silver-bearing product, as well as a high-strength iron-bearing solution that yields a saleable iron residue in the form of hematite.
Another significant patent focuses on the recovery of zinc from zinc-containing sulphidic material and zinc oxide-containing material. This process also addresses the presence of lead and/or silver values. By leaching these materials under pressurized oxidizing conditions, Doyle's method effectively separates the residue containing lead and silver from the leach solution, allowing for the recovery of these valuable metals.
