| Abstract | The alternative methods’ adoption for the mining tailings disposal is currently the basic strategy for such ventures’ viability. Once this problem basically refers itself to the wastewater containment, each alternative technique basic criteria must be focused on an effective reduction to the final product’s incorporation. In other words, the solution is to eliminate the water, producing dry wastes, also known as thickened waste. The following study presents a new method for dewatering waste pulp through series of cell lines, confined by metallic screens, provided with geotextile inner panels and discharge system for the recovery of as much water as to final transport of thickened tailings. The design of the proposed system, called UMD System Units (Mobile Dewatering), is presented and developed ahead and represents a low-cost deployment, with easy maintenance. It also has a great simplicity operation in confined areas of tailings areas. Studies have also shown that laboratory testing and lower scale models are the only tools that can effectively simulate the various events involved in the system’s fluid dynamics and geotextile-soil, called Gradient Ratio, is the most consistent alternative to refine the clogging potential, determined under different hydraulic gradients ratios. In this context, such a device was designed and built in UFOP – Federal University of Ouro Preto, having been completely validated by conducting the specific tests. |
