Abstract: Tailings in dressing plant of Lame Zinc Mine were discharged with low concentration，which caused such problems as high energy consumption，large water-waste，overproof heavy metal and water shortage in production in dry season and so on.Therefore，the current situation of tailing disposals in Lame Zinc Mine was analyzed in detail.Through the analysis of the nature of tailings，the composition and content of tailings were obtained and the tailings are mainly in medium-fine particle.With tailings settling tests，the flocculant dosage by which tailings slurry can achieve good settlement effect were measured，and the process and concentrated indicators of paste preparation were prepared.At the same time，through the slump tests and the loop conveyor of high concentrations of tailings slurry，a reasonable transportation plan was finally determined by calculating the concentration，volume and speed of slurry delivery.A set of the tailings disposal scheme being suitable for dressing plant of Lame Zinc Mine was put forward，that is，tailings slurry with concentration of 70% is considered as paste for transport.The scheme owns a series of advantages，such as water recycling in production，dry tailings stockpiling，less water wastes etc,.So，the scheme can solve the problems of tailing disposal currently faced by Lame Zinc Mine.
