Zinc smelter in Australia orders six SmartDivers

Date posted: November 4, 2020

Zinc smelter in Australia placed an order for six SmartDivers after a successful four months trial of one unit.

The trial unit was installed on a Paragorthite (PG) thickener to measure solids levels in the tank.  Measurements are being used for thickener control to optimize flocculant usage and underflow density.

Tests performed during the trial showed flocculant dose reductions up to 80% still had the tank under control and the overflow clarity within acceptable limits.  Just knowing what was happening in the tank allowed the process engineers confidence to make the massive reductions.

This site is not new to mud diver technology.  They have previously installed the older BTG divers which were discontinued about 10 years ago.  Although the BTG units were used to track the interface level continuously, they could not detect mud level.

The SmartDiver trial unit was installed by the site team.  Commissioning was done in collaboration with the PLA team in Melbourne which assisted remotely during this operation.  Training was also completed remotely.

The other SmartDiver units are intended to be installed on 2 by 6.5-metre-high rate thickeners running slurry at 140g/l of sulphuric acid at 87 deg C.
