His innovative approach aims to reduce the reliance on traditional flotation collectors, thereby enhancing the efficiency of the flotation process.
Latest Patents
Natarajan Ramanathan holds a patent for his invention titled "Flotation of sphalerite from mixed base metal sulfide ores either without or with largely reduced amount of copper sulfate addition using 2-(alkylamino)ethanethiols as collectors." The main objective of this invention was to develop a new flotation collector that could eliminate or significantly reduce the amount of copper sulfate used in the flotation of sphalerite. Through extensive research, he synthesized and tested various collectors, including cupferrons, arylhydroxamic acids, and amino mercaptans or amino thiols. His findings revealed that amino mercaptans/aminothiols were highly effective in floating sphalerite from lead-zinc ore, utilizing only 10-15% of the copper sulfate typically required with conventional xanthate collectors. Importantly, this innovation does not necessitate any alterations to current mill practices, requiring only a change in the flotation collector during the zinc flotation stage.
