| Summary: | The objective of this work is to determine the mechanical physical characteristics of the sterile mining wasteof the municipality of Marmato - Caldas, in order to technically evaluate the possibility of reusing the wasteas aggregate in the pavement mixture of tertiary roads and as adsorbent clay of heavy metals in miningwastewater from the same municipality. These residues correspond to the rocks and solid material extractedfrom the tunnels, which do not have a viable gold content. Small and artisanal miners dispose of this wastewithout any control or planning on the slopes surrounding the sinkholes (Jimena Motta-Pascuas et al., 2018).To carry out the current work, two samples of sterile mining waste were collected directly from the disposalarea of two mining tunnels at the sites known as “El Relleno” and “Cien Pesos” in the municipality of Marmato.Both samples were crushed in a gold beneficiation plant at the site known as “El Llano” in the samemunicipality. Then, technical tests were carried out in the soil laboratory of the SENA - Caldas Industrial andConstruction Processes Center. The results have determined the following properties: humidity, granulometry,density, PH, texture, conductivity and porosity. The results obtained will be analyzed to determine if thesterile waste complies with the regulations for the construction of tertiary roads and if it can be classified assome type of heavy metal adsorbent clay. |
