The information contained in this article, will help the operator to assess his/her systems, and identify where these systems fall within a three-level category. There are many ways, and opportunities to make a compressed air system produce reliable and good quality air. The three levels discussed here could also be characterized as a “continuous improvement plan” which can be achieved over the course of time, and with the occasional investment of money.

Logistics and supply problems are widespread on the African continent. Lack of infrastructure as well as capacity and efficiency deficiencies can affect supply chains and make them more expensive. Gold mines, which are often located in secluded areas, therefore seek to provide their entire infrastructure themselves. Even the oxygen required for efficient gold extraction by cyanide leaching is therefore not delivered but generated on site.

In the absence of the control system, the air compressors were loading and unloading according to pre-set pressure bands, which forced the system to operate at higher pressures and run inefficient combinations of compressors in order to effectively match air demand. When switched on, irrespective of air demand, the control system was able to control all compressors on a single, tight pressure band and efficiently match output with demand.
