Description
Метилиодпста со.ть сополимера диметиламиноэтилметакрилата с винилацетатом получаетс при взаимодействии сополимера , растворенного в бензоле, с йодистым метилом.Methyl iodopsta, a copolymer of dimethylaminoethyl methacrylate with vinyl acetate is obtained by reacting a copolymer dissolved in benzene with methyl iodide.
Метилиодиста соль сополимера диметиламиноэтилметакрилата и винилацетата представл ет собой белое кристаллическое вещество, хорошо растворимое в воде. В процессе выделени гли:нистых шламов Метилиодиста соль сополимера диметиламипоэтилметакрилата п винилацетата используетс в виде 0,25-0,5%-ных растворов.Methyl iodide salt of a copolymer of dimethylaminoethyl methacrylate and vinyl acetate is a white crystalline substance, well soluble in water. In the process of extracting the gly: methyl sulphide methyl iodide, a salt of a copolymer of dimethylaminopoethyl methacrylate / vinyl acetate is used in the form of 0.25-0.5% solutions.
Пример. Флотировали сильвинитовую руду в насыщенном по КС и NaCl растворе при отношении Т : : 2,5. Пульпу без реагента перемешивали 1 мин, затем последовательно вводили флокул нт полиакриламид и перемешивали в течение 1 мин, затем собирали метилйодистую соль сополимера диметиламиноэтилметакрилата и винилацетата и перемешивали в течение 1 мин.Example. Floated sylvinite ore saturated in KS and NaCl solution with respect to T: 2.5. The pulp without reagent was stirred for 1 min, then flocculant polyacrylamide was successively introduced and stirred for 1 min, then methyl iodide salt of dimethylaminoethyl methacrylate copolymer and vinyl acetate was collected and stirred for 1 min.
Шламова флотаци проводилась в течение 6 мин. Из обесшламленной таким образом пульпы после введени депрессора КМЦ п собирател сол нокислого октадециламипа извлекали сильвин.Sludge flotation was carried out for 6 minutes. Sylvin was removed from the pulp thus desulphided after the injection of the CMC n depressant of the hydrochloric octadecylamine was introduced.
Метилиодиста соль диметиламиноэтилметакрилата и винилацетата, исиользуема совместно с ПАА в качестве реагента - собирател шламов, вл етс хорошим собирателем дл флотации шламов из сильви итовой руды. ;При использоваиии метиллодистой соли сополимера диметиламиноэтилметакрилата и винилацетата извлечение глииистых шламов в шламовый иродукт повышаетс более чем в 1,5 раза, что сиособствует повышению эффективности последующей флотации сильвина. Извлечение сильвина в концентрат возрастает более чем на 5%, а содержание в нем н. о. уменьшаетс на 0,5-1,0%. При этом обращает иа себ виимание небольшой расход реагента метилиодистой соли сополимера диметиламипоэтилметакрилата и винилацетата, который составл ет в среднем 5-20 г/г руды. Таким образом, основное преимущество изобретеии состоит в повышении технологических иоказателей процесса флотации глинистых шламов из калийных руд.Methyl iodide salt of dimethylaminoethyl methacrylate and vinyl acetate, which is used together with PAA as a slime collector, is a good collector for flotation of sludge from sylvite ore. ; When using methyl-methyl salt of copolymer of dimethylaminoethyl methacrylate and vinyl acetate, the extraction of glial sludge into the slurry and product increases by more than 1.5 times, which contributes to the efficiency of the subsequent sylvine flotation. The extraction of sylvite in concentrate increases by more than 5%, and its content in it. about. reduced by 0.5-1.0%. In this case, a small consumption of the reagent of the methyl iodine salt of the copolymer of dimethylaminopoethyl methacrylate and vinyl acetate, which averages 5–20 g / g of ore, is reversing. Thus, the main advantage of the invention is to increase the technological indicators of the flotation process of clay sludge from potash ores.
