Title: Sharon Krumbein Rubin: Innovator in Gold and Bromide Recovery

Introduction

Sharon Krumbein Rubin is a notable inventor based in Kibbutz Naan, Israel. She has made significant contributions to the field of chemical engineering, particularly in processes related to the recovery of valuable materials from ores and aqueous streams. With a total of 3 patents, her work has implications for both environmental sustainability and resource recovery.

Latest Patents

One of her latest patents is a process for recovering gold from ores. This innovative method involves leaching gold-containing raw materials with an aqueous solution that includes elemental bromine and a bromide source. The process results in a pregnant leach solution where gold is dissolved, followed by the separation of this solution from the depleted raw material. The elemental bromine is then removed, and the gold is extracted in an acidic environment into an organic extractant. This leads to the formation of a gold-loaded extract and a bromide-containing raffinate. The extract is stripped with an alkaline aqueous solution to generate a gold-bearing aqueous solution, ultimately producing gold (Au) and treating bromide streams for recyclable elemental bromine.

Another significant patent focuses on bromide recovery from aqueous streams. This process involves providing a feed of halide-containing aqueous stream and contacting it with an anion-exchange resin to form a halide-loaded resin. The resin is treated with a regenerant and rinsed to produce various solutions, including a bromide-rich solution. This invention not only enhances bromide recovery but also offers an apparatus for carrying out the process.
