Description : An alternative method for dewatering slurry (tailings) is the use of geocontainers (MacTubes). The practical application of this work was carried out in the concentrator plant of the Raura Mining Company, located in the occidental mountain between Huánuco and Lima in Peru’s central highland. For the development of the research, the MATLAB R2012a software MGeST (v. 1.0) was used (Slurry Geocontainer Maccaferri Treatment). MGeST is used for sizing MacTubes, which allows determination of the most important design parameters, such as height (H), filling residual pressure (P↓0 ), strength of geosynthetic (T), and dehydration height. Compared with GeoCoPS v. 3.0, there is a maximum difference of 3% between the results obtained. The tailing to be treated in the MacTube have a specific weight of 11.62 kN/m3. After several tests it was determined that a MacTube of an apparent opening size of 0.22 mm was required for this specific weight.
