Overview

Potential leakage from tailings storage facilities (TSF) is a major risk for any mining or mineral processing operation.

Geomembrane is the most important component of TSF anti-leakage system, so the importance of geomembrane to TSF is self-evident, so how to choose a suitable geomembrane has become the most important thing in TSF.

The role of geomembrane in Tailings Storage Facilities

1. Prevent leakage: Geomembrane is a material with high anti-seepage properties that can effectively prevent liquids and pollutants in tailings from leaking into the surrounding environment. This is very important to protect soil, water sources and ecological environment.

2. Improve safety: Tailings storage facilities usually store large amounts of tailings. If a leakage or other safety accident occurs, it may have a serious impact on the surrounding environment and personnel. The use of geomembranes can improve the safety of storage facilities and reduce the possibility of accidents.

3. Cost savings: Compared with traditional tailings storage facilities, the use of geomembranes can reduce construction and maintenance costs. Geomembrane has a long service life and does not need to be replaced frequently. It can also reduce the occupation of land resources.

4. Comply with regulatory requirements: Many countries and regions have strict regulatory requirements for the anti-seepage performance of tailings storage facilities. The use of geomembranes can help companies meet these regulatory requirements and avoid legal risks and economic losses caused by non-compliance.

How to choose geomembrane for Tailings Storage Facilities(TSF)

1. Material quality: Choose high-quality geomembrane to ensure it has good anti-seepage performance, anti-aging performance and chemical stability. Geomembranes should comply with relevant national or industry standards and undergo quality testing and certification.

2. Thickness selection: Select the appropriate geomembrane thickness based on the characteristics of the tailings, the design requirements of the storage facility, and the expected service life. Generally speaking, thicker geomembranes have better puncture and tear resistance, but the cost increases accordingly.

3. Chemical resistance: Consider the chemicals that may be present in the tailings and select a geomembrane that can withstand these chemicals. Different geomembrane materials have different tolerances to chemical substances and need to be selected based on specific circumstances.

4. UV resistance: If the tailings storage facility is exposed to the sun, it is necessary to choose a geomembrane with good UV resistance to extend its service life.

5. Construction convenience: Choose geomembranes that are easy to install and connect to ensure efficient and reliable construction. The size, shape, and attachment of the geomembrane should match the design of the facility.

6. Cost-effectiveness: On the premise of meeting performance requirements, choose a cost-effective geomembrane. You can compare price and quality from different suppliers, taking into account other factors such as service life, maintenance costs, etc.

7. Supplier reputation: Choose reputable and experienced suppliers to ensure that they can provide high-quality geomembrane products and professional technical support.

Manufacturer’s Recommendations

When choosing a geomembrane, it is recommended to communicate and cooperate with professional engineers, designers or suppliers to develop the most suitable solution based on the needs and conditions of the specific project. At the same time, relevant regulations and standards should be followed to ensure the safety and environmental performance of tailings storage facilities.
