Controls on stibnite precipitation at two New Zealand

Conclusions Analysis of antimony concentrations in geothermal power plant fluids has been used to quantify the rate and magnitude of stibnite precipitation in two binary plants. At Rotokawa, 374 kg of stibnite per 6 months are predicted to form in the mixed brine-condensate heat exchanger.

A New Process For Sulfate Removal From Industrial Waters

A New Process For Sulfate Removal From Industrial Waters Many industrial wastewaters, particularly those associated with mining and mineral processing, contain high concentrations of sulfate. These concentrations typically exceed the secondary drinking water standard of 250 mg/L and may be subject to discharge limits between 250 and 2000 mg/L.

Antimony Cation Reactions

INTRODUCTION This is an account on how to detect Antimony ions in solution by simple precipitation reactions. Antimony is quite easy to distinguish since there are quite unique imsoluble compounds, however it has a similar amphoteric characteristics to metal cations such as Zinc, Aluminium, Lead, etc.

How to Precipitate Mercury from Gold Silver Cyanide Leach

Metal sulfides, such as calcium, sodium, silver, zinc, and iron sulfides, have been used to precipitate mercury from gold cyanide solutions. Silver sulfide would tie up considerable silver, and iron sulfide forms ferrocyanide, resulting in cyanide loss.

TECHNOLOGY OVERVIEW CHEMICAL PRECIPITATION

Sulfide Precipitation. The addition of a sulfide induces precipitation of dissolved metals as metal sulfides. This treatment is very effective for many metals, including zinc and cadmium. It is less effective for some contaminants such as manganese. If the MIW is acidic, pH adjustment may be required prior to the sulfide precipitation.
