The scrubbing of impurities from tantalum-loaded MIBK was investigated using dilute sulfuric acid as scrubbing agent in a cross-current system. The effects of various scrubbing parameters such as sulfuric acid concentration and scrubbing time have been investigated. Stripping studies of tantalum from the scrubbed tantalum-loaded MIBK were carried out using distilled water as stripping agent in a cross-current...
The kinetics of the forward extraction of TaF 72− by MIBK from stock was investigated using a Lewis cell. Different parameters such as the tantalum concentration, fluoride ion concentration, hydrogen ion concentration, and MIBK concentration, as well as extracting temperature were studied separately to examine their effect on the extraction rate of TaF 72− , and a rate equation...
