In recent years in Peru, there are few non-metallic mining companies, one of the main ones being the Santa Rosa 94-1 mining concession, which is located in the community of Llocllapampa Jauja - Peru, where the main resource is silica sand that is used in this place, although it also generates a negative impact on the siliceous sand washing operation process since it modifies the conditions of the surface water since they do not have a treatment system. The objective of the research is to determine the efficiency and the amount of organic coagulant (Zea mays var. saccharata) for the removal of silica from the effluent in the mining concession. The characterization of the silica was carried out through petrographic analysis to know its composition, the effluent of the Total Suspended Solids (TSS) parameter was characterized, then it was designed factorially for 8 treatments with variation ...
