BPM Membrana HDPE Liner for Mining Project in Tanzania
Membrana HDPE liner, also known as the HDPE geomembrane liner, is the preferred product for a wide range of containment lining applications. BPM membrana HDPE liner is cost-effective, excellent durable and exceptional chemical resistance to many different solvents, it is the most widely used lining material for exposed applications in the world. HDPE geomembrane liner has also higher specific strength, aging resistance from the intense stresses of weather. and can offer great ultraviolet protection, withstand higher temperatures. Due to the relative stiffness of HDPE material, trained technicians are required for on site geomembrane installation. BPM membrana HDPE liner uses the highest quality resins to manufacture the widest selection of high-density polyethylene (HDPE). It can be used in most projects where impermeability is required. ASTM GM13 HDPE geomembrane products available in either a black, green or white upper surface, and in either a smooth or textured single or double-sided surface for suitable application.
The use of BPM membrana HDPE liner may result in more productive mining due to the reliable lining system for mine containment and tailer treatment. New processes involving the heap leach method of precious metal extraction using chemical solutions have resulted in low cost extraction from low grade ores. On the one hand, the use of flexible geomembrane liners prevents the contamination of the soil and groundwater by these chemical solutions. Lining geomembrane under leach pads to minimize the potential for cyanide release is essential to the environmental protection. BPM membrana HDPE liner with excellent puncture and chemical resistance is the best selection for the containment lining systems to meet the severe requirement of the mining industry. On the other hand, Heap leaching has become the preferred method of recovering minerals from low-grade ore from open pit mines. Copper, gold, silver and other metals are most common. The metal deposits are dissolved by chemicals applied to the top of the heap of ore, which eventually leach to the bottom of the pile. Here a membrana HDPE liner captures the solution preventing it from migrating into the ground, before directing the solution by gravity to a collection system. The solution is sent to a refinery where the metal can be precipitated out and the solution sent back to the heap to be used again to dissolve more metal.
Our African customer was introduced to BPM by our long-term cooperation customer. He won mining project by bidding that needed membrana HDPE liner certificated with ASTM GM13 standard. After preliminary communication, we knew that the project needed 0.9 mm thickness HDPE geomembrane liner with and 8 meters wide and 110 meters in length used for the this project to prevent the contamination of the soil and groundwater by these chemical solutions. Our HDPE membrana HDPE liner products meet ASTM GM13 standard. Excellent tensile properties and low permeability can be suitable for the construction of many projects. They visited our geomembrane actory and personally watched the whole testing process of inspectors in our factory. Break strength of the HDPE geomembrane liner sample can reach to 25kn/m and Break Elongation is 800% based on ASTM D6693. It has surpassed ASTM GM13 standard. BPM geosynthetics customized three rolls of samples for customer testing. Customers were satisfied with our membrana HDPE liner products and placed the first order to us.
