WebEpithermal gold (± Cu & Ag) deposits form at shallower crustal levels than porphyry Cu-Au systems, and are primarily distinguished as low and high sulphidation using criteria of varying gangue and ore mineralogy, deposited by the interaction of different ore fluids with host rocks and groundwaters. Low sulphidation deposits are in turn further ... WebHigh-sulphidation deposits result from fluids (dominantly gases such as SO2, HF, HCl) channeled directly from a hot magma. The fluids interact with groundwater and form …
WebCarbon steel piping with low silica content is especially vulnerable to high temperature sulfidation. The Chemical Safety Board has defined low silica content as anything less than 0.1 wt% in carbon steel. But alloys, such as 5 chrome and 9 chrome, can be susceptible to high temperature sulfidation as well, just to a lesser extent than carbon ... Web0.1 wt% in carbon steel. But alloys, such as 5 chrome and 9 chrome, can be susceptible to high temperature sulfidation as well, just to a lesser extent than carbon steel. One of the safeguards that Shell implements is to change carbon steel piping to an alloy piping when that section of pipe is due to be replaced.
