Abstract


The activation Marmatite is one of the problems of separation of polymetallic sulfide ore in the world. Lancang the galena low iron sphalerite is about 7% Fe, the Yunnan Wenshan Dulong high iron flash the zinc mine iron up to 20% or more, and the price of metals were associated complex relationships difficult beneficiation studies using the new type of activator X -41 flash low iron and high iron zinc mine significant activation in low alkaline conditions. The Lancang low iron flash zinc mines and Dulong high iron sphalerite activation has a strong representation, Lancang low iron sphalerite and pyrrhotite, and other impurities mineral associated complex; Dulong High Iron zinc mine ore high iron ore contains a variety of valuable metals and associated rare metals. This thesis proceed from low iron and high iron sphalerite single mineral activation, and expect to be able to verify the new activator of X-41 efficiency and selectivity, to improve zinc concentrate grade and recovery purposes. Low iron and high-iron sphalerite single mineral sample were studied by a single bubble pipe (ie HaLimond tube), the the Cu2, NH4, Pb2, Ag and novel activators X-41 iron sphalerite activation effect. The results show that: the flotability low iron and high iron sphalerite natural poor can not use a single collector flotation. The not obvious activation of Cu2, NH4, Pb2, Ag traditional Marmatite activator, the new activator X-41 for low iron sphalerite single mineral flotation recoveries up to 67.2%; flash to the high iron The zinc mine single mineral flotation recoveries of up to 71.8%, significantly better than the Cu2, NH4, Pb2 and Ag activator. Lancang Lead Mine, and Wenshan have dragon scene ore laboratory flotation tests, the results further confirmed single mineral flotation concluded. New activator X-41 instead of copper sulphate activated iron sphalerite activation selective activation of the low pH value, and under the same process, the the Lancang low iron flash zinc mine using X-41 activation enables flotation Zinc concentrate grade increased by about 7.5%, the recovery rate of about 3.98%; the Dulong high Marmatite uses X-41 activation of to make flotation of zinc concentrate grade increased by about 5.52%, the recovery rate of about 4.18%. The the iron flash zinc mine activation mechanism studies, mainly from the crystal structure of the iron content, potential-pH value to analyze the activation mechanism of low iron and high iron sphalerite. The study confirmed the conclusions of the study of single mineral flotation tests and laboratory flotation test results theoretically. A single bubble tube test, laboratory test, and industrial test: New Activator X-41 iron sphalerite efficient activator, the desired pH value is not high, the cost is also lower than copper sulfate can be used as an alternative to the new agents promote the use of copper sulfate. The experimental and theoretical study of the papers on the Lancang Lead Mine and Wenshan Du Dragon mine iron sphalerite flotation activation achieved some important research results for future iron to sphalerite production practice has greater practical value and theoretical significance .
