"In the present context pulp is the unfiltered solution from ore leaching operations at mining sites. The possibility of utilising ion exchange or solvent extraction techniques for recovery from pulps has received much attention. Resin-in-pulp has been used in US plants but has never been used in Canada. So far neither the US experience nor any other studies have indicated that resin-in-pulp has any real advantage over the ion exchange purification of clear solution as practiced in Canada. However, solvent-in-pulp techniques appear more attractive because of the potential cost saving in capital and operating of filters, and because they decrease soluble metal losses encountered in a liquid-solids separation. The first successful work on solvent-in-pulp recovery of metals to be reported was that on the extraction of uranium from a sulphuric acid leach slurry of a flotation concentrate containing pyrite and graphite, using an amine extractant. The equipment used consisted of a 10in diameter extraction pulse column and three mixer-settlers for scrubbing, stripping and acid equilibration. A brief review of the highlights of this investigation, and subsequent work at the Mines Branch together with new information are described here with estimated processing costs"--p. 1294. gccst Metals gccst Processing Canada.
