GOLDEN SANDS

In view of what is happening on the Rand, fortunes may yet be made out of the treated and re-treated residues at Kalgoorlie and elsewhere in Western Australia. In pre-cyanide days dumps of tailings in and around Johannesburg contained several pennyweights of gold per ton. The contents were decreased by the leaching process to between ldwt and 2dwt, and still further reduced by tubemilling to ijdwt. Particular attention is now being given to the ldyft and 2dwt pilet, of which someone estimates theiv are about 70.000,000 tons on the itaml. With the assistance of a new pal*nl classifier, cosl« (including manageWw)'nnd red limping) can. it i>s ueserled, Incut uh line as 25 per ton, with 2d pe. ton yhipped olf wherever stope-iilliivj is going on simultaneously. Figures nil? quoted to show thut, taking residuu.worth from ldwt to l£dwt, and assuming the extraction to be- between 70 and 7b per cent., the profit would range from 7.8 d to 2s 3d per ton. If tlioKe profits can be made with Johannesburg tailings, there is (remarks the "Wild Cat" in tlw Bulletin) obvioubly bi^ luutuy hidden iv tonic of th« inutie»w« [nivt> of I'usidUta dumped iv the West.
