Sepon is an open pit copper mine situated in the southern Laos province of Savannakhet. The registered name of the operating company is Lane Xang minerals ltd (LXML) of which MMG owns 90% and the Laos Government owns 10%. In the early 2000,s the mine was operating as a Gold mine as well as copper, however the gold operation has now ceased and only copper is produced.
The Scrubber tank is of stainless steel construction and its purpose is to clean and rinse the ore as part of the process of copper production. Contained within the ore are traces of acid, the Stainless steel tanks can easily with stand this concentration of acid within the solution. However the concrete bund areas needed to be protected with a lining material that could also withstand this concentration of acid solution.
For the reasons stated above, Trepax were asked to install an acid resistant lining system to the concrete bund areas and up stand”s, to protect the concrete from the acid spillage of solution used in the cleaning process of the ore.
The concrete areas were lined with a glass reinforced vinyl ester chemical resistant lining system, to protect the concrete against acid solution spillages.
