chemical oxidation of a sulohide ore gold recovery

gold sulphide ore oxidation by alkaline pressure

acidic pressure oxidation of pyritic gold ore requires treatment temperatures between 160° to 210° c and pressures of up to 400 psig. the resulting residue requires thorough washing and neutralization prior to cyanidation. a high degree of sulfide oxidation usually ensures high gold recovery by cyanidation.

sulphide gold ore treatment by leaching and flotation process

problem with gold recovery from sulphide ore: how may a mill get the maximum recovery of gold from a sulphide ore at the least capital cost and at the same time obtain the highest net return. this latter point is most important. in many cases a gold mill using an all-cyanide flowsheet with fine grinding of all the ore will report very low gold content in the tailings particularly on an

planets guide by shadow. -there is a gold deposit in-between the signal and outpost. -there is a uranium deposit south of outpost -there is a salarium deposit south west of uranium deposit. it is essentially a rock of unremarkable ores with some deposits of water ice but no minerals of value.

recovery of gold in pyritic sulfide ores

recovery of gold in sulfide ores has fallen into several categories. first is froth flotation and second is cyanidation of the ores. using cyanide to recover gold from sulfide ores generally results in 30 to 35% recovery and the best i have heard of is around 50% recovery.

bacterial oxidation - wikipedia

the bacterial oxidation process comprises contacting refractory sulfide rom ore or concentrate with a strain of the bacterial culture for a suitable treatment period under an optimum operating environment. the bacteria oxidise the sulfide minerals thus liberating the occluded gold for subsequent recovery via cyanidation.

*there is a gold deposit in the center of the map north-east from the debris and south-west from the cobalt deposit. *a mummified salarian is nearby the gold deposit you should be able to see it on your radar if you search it: id tag recovered you discovered several small artifacts.

pressure oxidation - wikipedia

pressure oxidation is a process for extracting gold from refractory ore. the most common refractory ores are pyrite and arsenopyrite which are sulfide ores that trap the gold within them. refractory ores require pre-treatment before the gold can be adequately extracted.
