Recovery according to the process stages is the following:-solvent extraction — 99.5%;-solid-phase stripping — 99.36%; 89.1% of which precipitates as a salt of …

Another process that achieved Pt recovery efficiency of 85% involved the use of a NaCN solution at a ratio of 2:1 with reference to the treated raw material, ...

A variety of processing technologies exist for recovery from both primary and secondary sources of rhenium. Currently, there are no known primary rhenium …

In order to increase rhenium recovery in this process, some additives are used in the solution to oxidize the low valence rhenium oxide in the flue gas when using water scrubbing for pyrometallurgical rhenium streams (Zhang and Zhao, 2007). The …

Rhenium is always associated with porphyry copper. In the pyrometallurgical process of copper concentrate, rhenium in perrhenate (ReO 4−) form enters copper …

These catalysts can be processed in order to selectively separate rhenium and platinum. By using a NaHCO 3 solution to dissolve catalysts, up to 97% rhenium can be …

Abstract. Rhenium is utilized as an additive to improve the high-temperature strength and stability of materials, such as nickel-based superalloys, which are …

The article summarizes the research results on rhenium recovery with AM-p-2 strong-base macroporous styrene-divinyl benzene anion exchange resin with dimethylammonium functional groups from …

Figure 6 — Freeport pressure oxidation rhenium recovery process (Waterman et al., 2009). MINERALS & METALLURGICAL PROCESSING Vol. 30 No. 1 • February 2013 65

Rhenium production from copper and molybdenum sulphides involves the use of a pyrometallurgical process. In traditional pyrometallurgy processes, gases …
