BEC GO BACK TO SEPON

COPPER MILL CONTROLS

Lane Xang Minerals Limited is a member of the Oxiana Resources Group who operate the Sepon Copper Project at Savannakhet Province in Laos, 40km from the Vietnam border. The project is owned 100% by Oxiana and production commenced in early 2005. The ore rate varies from 0.8 to 1.3 Mtpa and at its peak the mine is expected to produce 60,000 tpa of copper.

Hired by Outokumpu, BEC were responsible for all electrical design and commissioning related to the installation of a primary ball mill and a smaller limestone mill. BEC also provided project management for all electrical controls engineering.

The mill control panel included local control and instrument display to ensure safe operation of instrumentation and sensing devices.

The ambient temperature at the minesite has extremes between 5°C and 45°C and humidty is high. The climatic conditions coupled with fine abrasive dust and acidic mist from the mine operations presented a challenge to BEC to ensure equipment was operational 24 hours every day of the year.

The control panel contained an Allen Bradley CompactLogix PLC system and PanelView 1000 touch screen. To prevent the internal temperature from rising above 50°C appropriate cooling was installed.
