Title: The Innovative Contributions of Ernest G. Parker

Introduction

Ernest G. Parker is a notable inventor based in Rossland, Canada, recognized for his significant contributions to the field of metallurgy and chemical processing. With a total of six patents to his name, Parker has developed innovative processes that enhance the efficiency of metal recovery and purification.

Latest Patents

Among his latest patents, Parker has developed a process for the precipitation of chloride from zinc sulphate solution. This process involves forming a slurry with an inert particulate support material that has elemental silver dispersed on it, along with an oxidizing agent. The slurry is agitated at temperatures between 60°C and 100°C to precipitate silver chloride on the support material. After filtering, the purified zinc sulphate solution is separated from the support material, which is then treated with a reductant in an aqueous alkaline medium to regenerate elemental silver.

Another significant patent by Parker focuses on the leaching of metal sulphides. This process allows for the separate recovery of elemental sulfur and residual sulfides from reaction slurries obtained from leaching metal sulfides in ores and concentrates. The method directs the flow of the reaction slurry into a separating step that comprises a substantially quiescent zone, where elemental sulfur coalesces and settles, allowing for the separation of dissolved metals and unreacted sulfides.
