Historically, both the BUTEX (dibutyl carbitol-based) and PUREX (tributyl phosphate-based) processes have been used for uranium recovery and purification. Currently, BUTEX- and PUREX-type extraction processes are being used in series for recovery of isotopically enriched uranium at the Oak Ridge Y-12 Plant. The use of two …
ABSTRACT Recently, a commercially available ethereal compound, cyclopentyl methyl ether (CPME) was found to act as an extractant for Au(III) in acidic chloride media. In this study, the extraction behavior of Au(III) using CPME was compared with commercial extractants dibutyl carbitol (DBC) and methyl isobutyl ketone (MIBK). …
Dibutyl carbitol (bis(2-butoxyethyl)ether; DBC), an ethereal compound, is currently the most popular extractant for Au(III) from hydrochloric acid media (Jung et al., 2009): Au(III) is selectively extracted from many precious- and base-metal cations. Typically, more than 99% gold extraction can be achieved and Au(III) can be …

Benefits. Solvent used to facilitate penetration into fibers and to promote the production of intense, bright shades; it features a high boiling point and low vapor pressure. Also an important solvent in nongrain-raising wood stains and serves as a component of industrial cleaners. Textile and dyeing processes utilize this product to ...
The ethereal compound dibutyl carbitol (bis(2-butoxyethyl)ether; DBC) is a common solvent used for the separation of gold during the refining of precious metals [9], [10]. DBC extracts Au(III) selectively over platinum-group metals and base metals. Au(III) can be extracted from a concentrated gold chloride solution with an associated high ...
Dibutyl carbitol. Fulminating gold. 1. IntroductionGold has mostly been extracted from its ores by cyanidation in the Carbon-In-Pulp process. The gold bullion produced from this process generally has to be further refined in mint shops to achieve 99.99% (4 N) purity (Marsden and House, 1992). Conversely, gold from scraps is mostly …
