Abstract:

Recovery valuable metal from cyanide tailing by flotation is difficulty.The main method currently adopted is to remove cyanide from tailing by adding oxidizing agents and then adding collector to recovery the objective minerals.However,there are some problems in the process,such as high cost of reagent,cyanide unable to reuse,and secondary oxidation of mineral surface.Taking cyanide tailings which contain high grade of lead and zinc in Shandong Province as research object,the flotation recovery of cyanide tailings was studied by flotation test and closed circuit test under the condition of non-cyanide removal,cyanide barren solution was used as flotation water.It was proved that valuable metals in the cyanide tailing can be recovery by flotation under the condition of non-cyanide removal.The cyanide tailing was processed to obtain qualified Pb concentrate with grade of 56.61% and recovery rate of 89.04%,Zn concentrate with grade of 32.6% and recovery rate of 74.5%.SEM microscopic study shows that the surface of copper mineral is insulated by a thin layer of galena,which changes the interface properties of chalcopyrite,and makes surface characteristics of copper minerals tend to interfacial properties of galena,leading to the majority of copper minerals entering into lead concentrates.

Key words:  cyanide tailing, galena, sphalerite, chalcopyrite, surface coating, flotation recovery, ultrafine tailings
