Why Does South American Mining Engineering Require Geosynthetics?

South America is known for its abundant mineral resources, leading to a thriving mining industry. However, large-scale mineral extraction inevitably faces issues of tailings dam safety and other associated risks. Therefore, the rational application of geosynthetic materials is a must on the path of South America's mining development.

South America has enacted multiple laws and regulations for the control of mining pollution, with very high requirements for impermeability. So the excellent HDPE geomembranes and are the preferred choices, which serves as the primary and secondary impermeable layers. HDPE geomembranes made from new raw materials has excellent oxidation, aging, acid, alkali resistance and creep resistance, while natural GCLs have an expansion coefficient of over 24ml/2g, and their combination can almost completely block tailings pollution of the soil.

In addition, due to the continuous destruction of surrounding soil during the entire mineral extraction period, the roads and slopes near the dam must be reinforced and stabilized. Therefore, geogrids used for reinforcement and protection of horizontal roads and slopes are important materials. Polypropylene (PP) geogrids can maintain excellent chemical resistance in the acid-affected & alkali-affected soil environment of tailings, and protect the safety of surrounding roads.

The demand for geosynthetics in South America's mining industry is technology-oriented, focusing on two core aspects: impermeability safety and structural stability. Zhonglong Environmental Protection has rich experience in supplying mining materials and can adjust production specifications according to project needs.
