Title: Innovations of Andrew B Case

Introduction

Andrew B Case is an accomplished inventor based in Harvey, LA (US). He has made significant contributions to the field of waste material treatment, particularly in recovering valuable elements such as chromium and aluminum from sludge. With a total of two patents to his name, his work demonstrates a commitment to environmental sustainability and resource recovery.

Latest Patents

Andrew B Case's latest patents include innovative methods for the recovery of chromium in a high purity state from waste materials. The first patent outlines a method for treating sludge containing substantial amounts of chromium, aluminum, calcium, iron, and phosphorous. This method involves forming a slurry of the sludge, reacting it with an acid, and separating the chromium/aluminum-containing solution from the solids residue. The process ultimately yields a high concentration, high purity chromate solution suitable for producing metallic chromium or various chromium chemicals.

The second patent focuses on reclaiming aluminum-chromium waste materials from etching operations. This method also involves forming a slurry of the sludge and selectively dissolving aluminum and chromium while leaving behind a solids residue. The process is designed to control the pH to precipitate undesirable elements without adversely affecting the dissolved chromium and aluminum. The resulting chromium/aluminum-containing solution is then treated to recover alumina.
