Title: J Michael Sierakoski: Innovator in Environmental Remediation
Introduction
J Michael Sierakoski is a notable inventor based in Tucson, AZ (US). He has made significant contributions to the field of environmental remediation, particularly in the removal of toxic substances from aqueous solutions. With a total of 5 patents to his name, Sierakoski's work has had a meaningful impact on both industry and environmental safety.
Latest Patents
One of his latest patents involves an ammonium thiosulfate complex of gold or silver and an amine. This innovative process focuses on the removal of toxic cyanide and heavy metal species from aqueous alkaline solutions. The method entails contacting these solutions with an extractant compound that can be protonated at a pH of 9 or above. This process effectively extracts anionic metal species from the solution, allowing for the subsequent stripping of metal values from the extractant and recovery of the metal species, preferably through electrowinning. This technique is particularly useful in flotation processes where a recycled aqueous process stream is employed, ensuring that toxic cyanide ions and anionic metal species are removed before the stream is recycled for flotation.
