Iridium extraction

The invention relates to a method for extracting iridium from iridium containing materials, in particular to a method for extracting iridium from rhodium and iridium containing solutions, iridium containing secondary resources or rhodium and iridium containing residues. The method is characterized by comprising the following extracting processes: (1) dissolving iridium containing materials

    May 03, 2021 SX was performed with the IL system, and the extraction studies were conducted at 298 K with an IL to aqueous phase ratio of 1:1(v/v). During extraction, the system was stirred at 2000 rpm for 5 min The extraction behavior of Ir(IV) as a function of A336 concentration was studied to determine the stoichiometry of the extracted metal complex

    Aug 26, 2010 Iridium(IV) extraction with petroleum sulfoxides (PSO) from hydrochloric acid solutions is studied. Optimum conditions of extraction are chosen. It is shown that in the investigated extraction systems for a phase contact time of 30 min, iridium(IV) is extracted by the ion-associative mechanism. Electronic, 1H NMR, and IR-spectroscopy, and elemental analysis are used to establish

    Mar 01, 1982 The extraction curve for iridium into tin (Fig. 1) indicates the limits of extractability, i.e. no extraction of iridium was observed to the right of the line. The well-defined area of separation between rhodium and iridium extraction shows that optimum separation of rhodium from iridium should be obtained if is held at 1.5 - 1.6 V

    The process of extracted rhodium in South Africa: Firstly, the other metals which are in the ore and quickly taken out. Next, what is left of the ore is treated with a salt like chemical- sodium bisulphate and melted. After that, we are left with a type of salt of the rhodium. The rhodium is then extracted and many other steps can be taken to
