Description
Известны способы флотации руд с подавлением медных и железных минералов.Known methods of ore flotation with the suppression of copper and iron minerals.
Предлагаемый способ отличаетс от известных тем, что в качестве реагентов-подавителей примен ют синтетические водорастворимые сополимеры , содержащие одновременно CN-грунны и гидрофильные группы ОН, СООН н др.The proposed method differs from the known ones in that synthetic water-soluble copolymers are used as suppressant reagents, containing both CN-soil and hydrophilic OH, COOH and other groups.
Применение такого способа обеспечивает эффективное и избирательное подавление указанных минералов.The use of this method provides an effective and selective suppression of these minerals.
Флотаци руд но предлагаемому способу основапа па том, чтО синтетические водорастворимые полимеры, содержащие нар ду с весьма гидрофильными группами также и нитрильную грунну, очень резко подавл ют медные и железные минералы и лищь слабо подавл ют свинцовые минералы. К числу таких избирательных подавителей относ тс сополимеры акриловой кислоты и акрилиитрила, сополимеры моноакрнловых и монометакриловых эфиров мпогоатомных спиртов с акрилнитрилом , а также полимеры, полученные прививкой акрилнитрнла на высокомолекул рные гидрофильные соединени - декстрин, крахмал, поливиниловый спирт.The flotation of the ore according to the proposed method, based on the fact that synthetic water-soluble polymers, which also contain nitrile soil along with very hydrophilic groups, very strongly suppress copper and iron minerals and weakly weakly suppress lead minerals. Among these selective depressants include copolymers of acrylic acid and akriliitrila copolymers monoakrnlovyh and monometakrilovyh mpogoatomnyh esters of alcohols with acrylonitrile, as well as polymers obtained by grafting akrilnitrnla to hydrophilic high molecular weight compound - dextrin, starch, polyvinyl alcohol.
Предлагаемый способ может примен тьс при флотационном разделении медных и железных минералов от свинцовых, молибденовых н других руд.The proposed method can be used in the flotation separation of copper and iron minerals from lead, molybdenum and other ores.
