Title: Douglas R Shaw: Innovator in Mineral Recovery Processes

Introduction

Douglas R Shaw is a notable inventor based in Arvada, CO (US), recognized for his contributions to the field of mineral recovery. With a total of 2 patents, Shaw has developed innovative processes that enhance the extraction of valuable minerals from ores.

Latest Patents

Shaw's latest patents include a selective flocculation process for the recovery of phosphate. This process involves separating and recovering non-metallic minerals, particularly phosphate, from ores containing non-uniform sized particles, including colloidal particles. The ore is slurried in an alkaline, aqueous solution with a dispersing agent. A flotation collector is added, and the mixture is contacted with a hydrophobic, high molecular weight, nonionic polymer to flocculate the fine particles, making them amenable to subsequent flotation. Additionally, he has developed a sequential flotation process for the recovery of high-grade concentrates of copper, lead, and cobalt-nickel from sulfide ores. This process conditions a primary grind ore pulp with SO₂ as H₂ SO₃ under intense aeration, followed by sequential flotation, regrinding, and conditioning of the copper rougher concentrate obtained in the first flotation step.

Career Highlights

Throughout his career, Douglas R Shaw has worked with prominent companies in the mining and mineral recovery sector, including Anschutz Mining Corporation and Resource Technology Associates. His expertise in mineral processing has made significant impacts in the industry.
