Abstract:Organic polymer flocculant has been used for many years in Tonglushan mine, but because there are so many manufacturers and product variety for flocculant and the purchase price is also different on the market at present, which has increased the difficulty of flocculant selection and procurement and application. In order to screen out the suitable flocculant type for total tailing settlement of Tonglushan mine and reduce the cost of flocculant, the solubility test in water and settlement comparison test has been carried out between four kinds of best-selling brands polymer flocculants on the market and flocculants used in production site, then the production cost has been calculated on the basis of the experimental research in this paper. The research results show that under the dosage of 18g/t, the tailing settlement speed for the five kinds of flocculants from fast to slow is arranged in the following order: YD-6, A556, A345, JC186, 3660DF. And when the settlement speed is faster, the concentration of settlement layer is higher. Among which the best dosage for three kinds of flocculants at A345, A556, YD-6 with better settlement effect are 21g/t, 18g/t, 18g/t, respectively. Finally, considering the test effect and production cost consumption of flocculant, the flocculant of YD-6 is recommended, and the production dosage is 18g/t.
