Title: Alfred S. Hayden: Innovator in Precious Metal Extraction

Introduction

Alfred S. Hayden is a notable inventor based in Richmond Hill, 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

Hayden's latest patents focus on innovative methods for extracting silver and gold from ore materials. One of his patents describes a two-stage extraction process that improves the efficiency of recovering these precious metals. In the first stage, a portion of the silver and gold is extracted using a cyanide leach solution. The leached solids are then treated with activated carbon at elevated temperatures, allowing for the adsorption of silver and gold. In another modification, a slurry of the ore material is treated with cyanide, and the precious metals are directly adsorbed from the slurry using activated carbon at temperatures up to about 70 degrees Celsius. His second patent addresses the aqueous oxidation of refractory sulfidic silver ore, which is not suitable for cyanide leaching. This process involves forming an aqueous slurry of the ore and oxidizing it at elevated temperatures in the presence of an oxidizing agent, typically oxygen, along with zinc. This method significantly increases the extractability of silver from the oxidized residue.
