Title: Innovations by Inventor Fritz-Peter Sawyer

Introduction

Fritz-Peter Sawyer is an accomplished inventor based in Spring Creek, NV, USA, who has made significant contributions to the field of mineral processing. With a patented technology that focuses on the recovery of gold from refractory gold-bearing sulfidic minerals, Sawyer's work demonstrates the innovative application of biooxidation processes in mining.

Latest Patents

Sawyer holds a patent titled "Processing of acid-consuming mineral materials involving treatment with acidic biooxidation effluent." This innovative method provides a pathway for recovering gold from at least two different types of refractory gold-bearing sulfidic mineral materials. The process involves subjecting a first mineral material to biooxidation pretreatment, effectively releasing gold locked within sulfide minerals. The resulting acidic biooxidation liquor effluent, which contains dissolved iron in ferric form, is then utilized to treat a second mineral material rich in acid-consuming minerals. This unique treatment raises the solution pH and causes precipitation of dissolved iron and other metals, thereby enabling the release of gold from sulfides in the second mineral material for subsequent recovery.
