Non-tailing treatment method for metal mine flotation tailings
PendingCN119456186Alow pricereduce yieldFlotationWet separationOXALIC ACID DIHYDRATETricarboxylic acid
The invention discloses a tailing-free treatment method for flotation tailings of a metal mine, which comprises the following steps: adding oxalic acid into ore pulp of the flotation tailings of the metal mine to adjust the pH value of the ore pulp, and then adding butyl xanthate and terpenic oil for sulfur roughing; performing blank concentration on a foam product obtained by sulfur roughing for three times to obtain sulfur concentrate; the method comprises the following steps: performing low-intensity magnetic separation on sulfur separation tailings obtained by sulfur roughing, performing sedimentation desliming on the tailings obtained by low-intensity magnetic separation to obtain micron-sized fine silt and a crude product, performing roughing on the crude product for five times, adding an adjusting agent of oxalic acid and 2-hydroxypropane-1, 2, 3-tricarboxylic acid combination, lauryl amine and sodium oleate in each time of roughing, blank concentration is conducted on a foam product 1 obtained through first-time roughing to obtain feldspar concentrate 1, foam products and micron-sized fine silt obtained through subsequent roughing are filtered and dried to obtain feldspar concentrate 2, and after fifth-time roughing is finished, ore pulp is filtered and dried to obtain quartz concentrate. The problem of land and environment damage caused by tailing stockpiling can be solved, and tailing resource utilization is achieved.
