Title: Innovations by Chandulal P Patel in Precious Metal Extraction

Introduction

Chandulal P Patel is a notable inventor based in Vancouver, Canada. He has made significant contributions to the field of precious metal extraction, holding 2 patents that enhance the efficiency of extracting valuable metals from ores.

Latest Patents

One of his latest patents focuses on the extraction of precious metals from ores, specifically improving the efficiency of silver and gold extraction from ore materials containing active carbonaceous material. This innovative process involves conducting the extraction in two stages. In the first stage, a portion of the silver and gold is extracted using a cyanide leach solution. The leached solids residue is then contacted with activated carbon, allowing the silver and gold to be adsorbed at elevated temperatures, ideally between 35°C and 100°C. In a modification of this process, a slurry of the ore material is treated with cyanide, and the precious metals are adsorbed directly from the cyanided slurry with activated carbon at temperatures up to 70°C.

Another significant patent by Patel addresses the aqueous oxidation of sulfidic silver ore. This method involves forming a refractory sulfidic silver ore into an aqueous slurry and oxidizing it at elevated temperatures, typically between 150°C and 250°C, in the presence of an oxidizing agent, usually oxygen, along with zinc. The presence of zinc enhances the extractability of silver from the oxidized residue through cyanide leaching.
