Title: Innovations of Dennis L Howe in Nickel Recovery

Introduction

Dennis L Howe is an accomplished inventor based in Broomfield, Colorado. He has made significant contributions to the field of metallurgy, particularly in the recovery of nickel and cobalt from laterite ores. With a total of 2 patents, his work focuses on environmentally sustainable methods for metal extraction.

Latest Patents

Dennis L Howe's latest patents include a "Method of recovering nickel from laterite ores." This innovative process separates ores into high and low magnesium fractions. The low magnesium fraction is then leached with sulfuric acid at elevated temperatures and pressures to solubilize valuable metal values. The resulting pregnant liquor is treated to remove contaminants, leading to a dischargeless process that is both environmentally and economically viable. Another notable patent is the "Method of liberating nickel- and cobalt-enriched fines from laterite." This method involves atmospheric or low-pressure leaching of lateritic ores, resulting in a fines fraction that is richer in nickel and cobalt.
