Latest Patents
One of Inderjit Nirdosh's latest patents is 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 reduce the amount of copper sulfate used in the flotation of sphalerite. Different series of collectors, such as cupferrons, arylhydroxamic acids, and amino mercaptans or amino thiols, were synthesized and tested. Amino mercaptans/aminothiols were found to be very effective in floating sphalerite from a lead-zinc ore using only 10-15% of the copper sulfate used with conventional xanthate collectors. This invention does not require any alteration in current mill practices, warranting only a change in the flotation collector in the zinc flotation stage.
Another significant patent involves the "Determination of surface and interfacial tension." This invention pertains to the determination of the surface tension of a liquid or the interfacial tension between two immiscible liquids using drainage methods. The apparatus used, which includes a tapered tube, a rotating uniform diameter tube, or a tilted uniform diameter tube, is simple, inexpensive, and capable of providing accurate measurements.
