Since the beginning of civilization, people have used stone, ceramics and, later, metals found close to the Earth's surface. These were used to make early tools and weapons; for example, high quality flint found in northern France, southern England and Poland was used to create flint tools.[2] Flint mines have been found in chalk areas where seams of the stone were followed underground by shafts and galleries. The mines at Grimes Graves and Krzemionki are especially famous, and like most other flint mines, are Neolithic in origin (c. 40003000 BC). Other hard rocks mined or collected for axes included the greenstone of the Langdale axe industry based in the English Lake District.[citation needed] The oldest-known mine on archaeological record is the Ngwenya Mine in Eswatini (Swaziland), which radiocarbon dating shows to be about 43,000 years old. At this site Paleolithic humans mined hematite to make the red pigment ochre.[3][4] Mines of a similar age in Hungary are believed to be sites where Neanderthals may have mined flint for weapons and tools.[5]

The concentrate tested was a flotation concentrate from the Northmet project, USA, assaying 14.7% Cu, 3.05% Ni, 0.14% Co, 26.7% S, 1.4g/t Au, 2.2g/t Pt, and 9.9g/t Pd. Pressure-oxidation conditions were 225C, pulp density was 11%, retention time was 120min, and oxygen overpressure was 689kPa. The ore treated had a P80 of 15m. After solidliquor separation, the gold and PGMs were recovered by sulfide precipitation using NaHS or by activated carbon. The copper was recovered using conventional solvent extraction and electrowinning techniques. Overall recoveries were Cu 99.6%, Ni 98.9%, Co 96%, Pd 94.6%, Pt 96%, and Au 89.4% (Ferron etal., 2000). Studies in treating a variety of refractory gold concentrates under optimum conditions (225C, NaCl 1020g/L, 26h O2 at 700kPa) achieved gold extractions of the order of 9096% compared with direct cyanidation where gold extraction was less than 20% (Ferron etal., 2003)
