small scale ion exchange gold recovery

Nutrient Recovery

Nutrient Recovery. Nitrogen and phosphorus will be recovered from the secondary effluent using ion exchange media. Phosphorus will be removed by adopting a hybrid ion exchange media (HAIX) for phosphorus removal and ammonia will be removed using Mesolite which is a type of zeolite.

In situ leach - Wikipedia

In-situ leaching (ISL), also called in-situ recovery (ISR) or solution mining, is a mining process used to recover minerals such as copper and uranium through boreholes drilled into a deposit, in situ.In situ leach works by artificially dissolving minerals occurring naturally in a solid state. For recovery of material occurring naturally in solution, see: Brine mining.

This "spent" solution yields mostly copper sulfide on evaporation. This material, however, should be presumed to contain at least trace amounts of silver; it may be saved for future recovery operations (e.g., ion exchange). Method A is obviously much better when the starting silver and other reagents are already 99.9+% pure.

Brine mining - Wikipedia

Brine mining is the extraction of useful materials (elements or compounds) which are naturally dissolved in brine.The brine may be seawater, other surface water, or groundwater.It differs from solution mining or in-situ leaching in that those methods inject water or chemicals to dissolve materials which are in a solid state; in brine mining, the materials are already dissolved.
