High-pressure oxidation comprises the oxidisation of sulphide/carbonaceous gold ore at high pressure and temperature. Temperatures exceeding 200 °C and oxygen pressures above 2200 kPa are used to attain complete oxidation of the gold-bearing ore. Reaction rates can be very fast, and the technology is widely-accepted.

What happens is that any particle of gold only needs to dislodge a particle of like size but lesser density and since gold has a sg of 19.3 and most rock is around 3, it happens fairly easily. Something you should understand is that water is not only injected from behind the material trapped in the rings but it is also injected tangentially in ...
Mohamed et al [2] reported that the use of CTW and CSW as sand replacement resulted in low density FSC that is 1220 and 1222 kg/m 3 respectively. This is due to low density of ceramic wastes compared to natural fine aggregate and also increment in porosity induced by ceramic wastes.
