Registered Adroit System Integrator NC Automation Engineering has completed a R12-million flotation plant upgrade at Botswana nickel and copper producer BCL,
where it has commissioned a GE FANUC 90-30 PLC and a 1500 tag Adroit supervisory control and data acquisition (SCADA) system with four remote clients.
The US$2-million overall turnkey project for the replacement of existing rougher and scavenger flotation cells was awarded to Baker Process in the United Kingdom.
“This project incorporates the latest technology available,” says Baker’s regional minerals manager Dave Woodruff. Managing member of NC Automation Jason Wright echoes this by saying, “the project fully utilizes the open-system nature and powerful new features of the locally developed and supported Adroit system.”
“The SCADA not only interfaces with the plant control PLC via an OPC server but also with intelligent on-line Outokumpu analyzers and a management database,” he enthuses.
This allows for rapid adjustment of reagent dosing without physically having to take samples to a laboratory for testing.
“Also, with Information Technology growing as a component of industrial automation, the Adroit remote clients together with our custom built, user friendly Management Information System, ensure that the plant managers are kept totally up to date with the live and historical performance of the plant, including maintenance records from their office desktop,” he points out. It also allows plant metallurgists to analyse thousands of logged process samples with powerful yet simple-to-use tools in order to fine-tune the dosing models and to improve the plant recovery.
