Determination of dissolved oxygen in cyanide leaching process
The ion selective electrode tester greatly simplifies the determination of dissolved oxygen and enables the determination to be carried out on site without relying on laboratory colorimetry.The current electrode and polarographic probe are used, and the current is used to measure the dissolved oxygen content in the electrolyte solution.
Ion-selective dissolved oxygen meters are fixed and portable, which are available for users to choose.It should be noted that this instrument can effectively give an indication relative to the oxygen saturation state, but is less sensitive to changes in factors such as temperature, pressure, salinity and slurry viscosity. Therefore, despite various correction measures, the error of actual dissolved oxygen content measured is still large.
Oxygen - enriched leaching is a new technology, which is simple and effective, has been applied to industrial production.An industrial experiment conducted in a carbon in pulp plant showed that after the oxygenation measures were taken on the current open-type leaching tank, the concentration of dissolved oxygen in the cyanation solution increased from 8 x 10-6 to 20 x 10-6, and the leaching speed of gold more than doubled.This new technology can be used in the construction of new cyanidation plants, which can significantly save investment, and can be used in the renovation of old cyanidation plants, which can expand production capacity without increasing cyanidation equipment, so it has a broad application prospect, which has been widely paid attention to by domestic and foreign research and production fields.
