Textured HDPE Pondliner for Tailings Treatment Project in Peru - Case Study
BPM Peru customer asked us to purchase HDPE pondliner and other geosynthetic products for the anti seepage liningtailings treatment project. BPM provided customers with 52,150 square meters geomembrane pondliner and 20,400 square meters geotextile，5,698 square meters drainage net, 5,000 square meters geosynthetic clay liners. Peru is rich in mining resources, and the mining and petrochemical energy industries are relatively developed. With the development of the economy, the demand for mineral products has increased substantially, and the mining development plan has increased accordingly, and the number of beneficiation tailings will continue to increase; in addition, the grades of many available metal mines are declining, in order to meet the increasing demand for mineral products As the beneficiation plan is getting bigger and bigger, the number of beneficiation tailings will also increase, and a lot of piled tailings pose many problems to mining, environment and economy.
The treatment method of tailings is generally as the filling material of the underground mining goaf of the mine, that is, the water-sand filling material or the aggregate of cemented filling; perhaps some of them are directly covered with soil on the tailings accumulation site to cultivate crops or plant trees. In fact, the most economical way to deal with tailings is still sand making from tailings and materials used as building materials. For example, the treated tailings can be used as cement, tile, aerated concrete, permeable bricks, fire-resistant materials, fire-proof insulation materials, and glass. Ceramsite, concrete aggregate and other materials, tailings sand can replace part of the machine-made sand to make concrete, build roads, road materials, etc.
The advantage of using geomembrane pondliner for tailings dams is that when tailings contain toxic or radioactive substances or heavy metal ions, in principle it is not allowed to contain harmful substances to pollute the groundwater, so seepage prevention treatment is required.
As the leading geosynthetic products manufacturer and wholesaler, The Best Project Material Co., Ltd (BPM) has dedicated to manufacturing and supplying one stop geosynthetic solutions and services to worldwide customers since its foundation in 2010. We have over 120 professional staff and 16,000 square meters manufacturing factory equipped with state of the art production lines. Our innovative, high quality geosynthetic solutions include geomembranes, geotextiles, geocells, geosynthetic clay liners (GCLs), drainage boards, geogrids, etc. All BPM brand geosynthetic products have been pass the certificates of ISO9001, ISO14001, Soncap, SASO, BV and passed the test of SGS and Intertek etc.As a waterproofing liner, HDPE geomembrane pond liner is favored over other materials for its modest economic and operational advantage. Economically, HDPE geomembrane pondliner is superior thanks to its relatively straightforward manufacturing process, which has driven up supply and kept prices low in contrast to other kinds of geomembranes.
Furthermore, hdpe geomembrane pondliner is a very stable polyolefin that is chemically inert and able to maintain long-term integrity and durability. These properties make the HDPE membrane a popular choice to waterproof and mining, landfill and other containment applications.
BPM Textured geomembrane podnliner is produced by the spray texture technology. It is designed with one or two side textured surface. Except for the excellent properties of smooth geomembrane, it also has better interface friction coeffcient and UV resistance. This increased the slope stability and skid resistance which fit for steep slope or vertical geotechnical projects such as mining.
We recommended the 2mm textured geomembrane pond liner and 400g PP geotextile to the customer. Through communication, the customer finally chose the 1.5mm textured geomembrane and 270g PP geotextile. We sent the customer product pictures, production videos, and certification certificates etc, and communicate product details with customers.
But the customer needs to increase the rough surface height based on the American standard. We will communicate the customer’s requirements with the production department, and test according to the customer’s specifications and indicators, produce two pcs of 2m*2m samples, and Samples of geotextiles, composite geonet and geosynthetics clay liner send to customers together for their reference. After the customers received them, they immediately arranged to go to the local laboratory for testing. Our products fully met the requirements and finally reached a cooperation.
Specifications of Textured Geomembrane HDPE Pondliner for Tailings Treatment Project
- Total textured geomembrane quantity –52,150m2
- Geomembranespecification – 1.5mm
- Each roll size is 7m*50m
BPM Non-woven geotextile fabric is also a kind of chemical material of polymer short fiber. After needle punching or thermal bonding, it has high tensile strength and extensibility, and has good corrosion resistance to bacteria and chemical effects. It is not afraid of acid and alkali. , Salt corrosion, in the case of dark use, the service life is longer.
BPM composite drainage net is made of special three-dimensional geotextile with double-sided adhesive and nonwoven geotextiles. Integrating geotextile (filtration) and geotextile (drainage and reinforcement), it has the overall effect of “filtration, drainage and protection”.3D composite drainage network unique 3D structure, in the use of the process can withstand high pressure load, and can maintain a considerable thickness, high tensile strength, corrosion resistance, acid and alkali resistance, strong drainage capacity, so as to provide a high water conductivity.
BPM Geosynthetic clay liners is a new geosynthetic material.The bentonite waterproof blanket is made by mixing the graded natural sodium bentonite particles and the corresponding admixtures evenly. The bentonite particles are fixed between two layers of geotextiles by special technology and equipment, which has both all the characteristics of geotextile and excellent waterproof (permeability) performance.The waterproofing mechanism is as follows: the bentonite particles swell with water, making it form a uniform colloid system; under the restriction of two layers of geotextile, the bentonite expands from disorder to orderly; continuous water absorption and swelling result in the bentonite layer itself compacting, thus having the waterproof effect.
We sent the production schedule to the customer, test each batch of products, and feedback the test data to the customer in time, so that the customer can know more about the production situation and product quality at any time.
