Mineralogy and geochemistry of tailings from a gold mine

10-10-2016ABSTRACTMineralogical and geochemical characteristics of tailings from a gold mine in northeastern Thailand were investigated in relation to acid mine drainage (AMD) and the release potentials of toxic elements The tailings can be divided into upper tailings and lower tailings The upper tailings usually contain pyrrhotite pyrite

Tailingsfo What are tailings?

Mine tailings are the ore waste of mines and creates very long-term environmental liabilities which future generations must manage Many mine tailings do not become appreciably safer over time such as the cyanide used in gold mining remain in the tailings at the end of the process and may leach out into ground water

Paper Characterization of Cyanide in Gold Mine Tailings

However at most gold mines in South Africa cyanide is simply discharged with the effluent and tailings based on the assumption it will decompose within a relatively short period of time However the distribution and fate of cyanide in the environment upon release from the tailings dumps depends on its physical-chemical speciation

Cyanide Destruction Methods and Processes

Detoxification processes are used to reduce the concentrations of toxic constituents in tailings streams and process solutions either by dilution removal or conversion to a less toxic chemical form (sometimes referred to as"destruction" or "degradation" in the case of toxic cyanide species)
