1 Estimation of the water footprint in a small scale gold ore beneficiation plant located in the municipality or Vetas, Santander, Colombia. Walter Pardavé Livia , Grupo Ambiental de Investigación Aplicada Universidad de Santander Pedro Luís Delvasto Angarita, Escuela de Ingeniería Metalúrgica y Ciencia de Materiales Universidad Industrial de Santander Bucaramanga Colombia, RESULTS The sampling of flows was carried out by means of selected plastic flasks, of known calibrated volume (ml). The time of filling was measured using a chronometer and annotated as hundredths of a second (CS). For rock material with low water content, the water the flow was estimated from the weight percentage of water in the solid material. The time lapse related to the stream of solid material was obtained from production data available in the “Reina de Oro” plant. CONCLUSIONS The determination of the flow rates corresponding to each unit operation shows that the operation of the mill as initial zone consumes a blue water sub-footprint equal to 1.14 m3 daily the two wilfley tables located in the gold processing and recovery plant show a use of water for Its process of 0.55 m3 per day and the final stages of sedimentation of the tails and media of the mineral, the subsequent shedding of process tailings to the Suratá River and the process of casting the obtained concentrates show a consumption equal to 5.16 m3 per day REFERENCES [1] University of Twente, the Netherlands.
