Modern methods for recultivation of tailing dumps

Lands resulting from the flotation tailings and disposal of tailing have no biotic potential, so it is necessary to apply modern methods for remediation for these lands to have a particular purpose. To have a successful recultivation, it is necessary first to remove the water from the tailing dump. Dewatering can be done by several methods depending on the application/usage of the terrain after recultivation. The process of dewatering can be performed by application of geotextile with woven grid, and then adding burden on tailing dumps or by preparing vertical piles and adding of the burden. If at site where tailing dump is situated, buildings are foreseen to be constructed it is necessary the tailing dump to meet the geo mechanical conditions. During the recultivation of tailing dumps it is best if flotation tailing is completely isolated from humus material by placing geosynthetic materials (geotextiles, geomembrane, drainage geocomposite, geogrid). Hence, before applying humus geosynthetic materials are placed, and isolation of tailings, stable conditions, erosion protection are accomplished. For more successful emergence of vegetation on the slopes of tailing dumps modern material Biomac S/C can be used, material made of coconuts and straw merged with polypropylene network which material is used for the recultivation in Republic of Macedonia and excellent results are achieved
