LEAN DUPLEX STAINLESS STEEL FOR CCD TANKS IN THE MINING INDUSTRY

In the Mining industry NDE led the change over 20 years ago to the use of LDX2101 stainless steel for counter current decantation (CCD) tanks where crushed ore is treated.

The new stainless steel material was cheaper than the original rubber-lined, painted mild steel and was stronger, plus it minimised maintenance.

A second benefit was that the lighter lean duplex material allowed for lighter components including the rake arms, a smaller motor, smaller gearbox and less electrical power to operate.

So the choice of new material specified gave:

  1. a better technical result
  2. a first off cost saving
  3. a running cost saving
