Description
Дициклогексилдитиокарбамат натри значительно менее токсичен, чем ксантогенаты.Sodium dicyclohexyl dithiocarbamate is significantly less toxic than xanthate.
Основным сырьем дл синтеза дициклогексилдитиокарбамата натри служит дициклогексиламин, вл ющийс побочным продуктом в цроизводстве капролактама. Дициклогексиламин может быть получен также гидрированием дифениламина. Сырье дл синтеза дициклогексилдитиокарбамата натри доступно и недорого, а технологи его изготовлени аналогична технологии изготовлени ксантогената.The main raw material for the synthesis of sodium dicyclohexyldithiocarbamate is dicyclohexylamine, which is a byproduct in the production of caprolactam. Dicyclohexylamine can also be obtained by hydrogenation of diphenylamine. The raw material for the synthesis of sodium dicyclohexyldithiocarbamate is affordable and inexpensive, and its manufacturing technology is similar to that of xanthate.
Предлагаемый способ флотации благодар высокой химической активности дициклогексилдитиокарбамата натри и длинной апол рной части его молекулы позвол ет увеличить извлечение металлов из окис№ 125207-- 2 - .ченных и смешанных руд. Кроме того, при испо.чьзовании дициклогексилдитиокар0амата натри , в отличие от бутилксантогената, можно полностью извлекать малахит и церуссит без сульфидизации. Это позвол ет изрлек&т ,3 концентраты благородные металлы, которые при флотации малахита и церуссита ксантогенатом с г:ульфидизацией подавл ютс сернистым натром и безвозвратно тер ютс . Малахит извлекаетс практически полностью при расходе дициклогексилдитиокарбамата натри 2,0 моль/т. Церуссит извлекаетс полностью при расходе дициклогексилдитиокарбамата 1,5 , а с бутилксантогенатом в этих услови х извлекаетс только 64,0% и дальнейшее увеличение расхода бутилксантогената почти не увеличивает извлечени церуссита. Полное извлечение сернистого железа происходит также нри значительно меньnjcM расходе дициклогексилдитиокарбамата натри .The proposed flotation method, due to the high chemical activity of sodium dicyclohexyl dithiocarbamate and the long apolar part of its molecule, allows increasing the recovery of metals from oxide 125207-- 2 - combined and mixed ores. In addition, when using sodium dicyclohexyl dithiocaromat of sodium, unlike butyl xanthate, malachite and cerussite can be completely removed without sulfidization. This allows isletting & t, 3 concentrates of noble metals, which during the flotation of malachite and cerussite with xanthogenate with g: ulphidization are inhibited by sulphide soda and irretrievably lost. Malachite is recovered almost completely at a sodium dicyclohexyldithiocarbamate consumption of 2.0 mol / ton. Cerussite is extracted completely at a consumption of 1.5 dicyclohexyldithiocarbamate, and with butyl xanthate, only 64.0% is recovered under these conditions, and a further increase in consumption of butyl xanthate hardly increases extraction of cerussite. The complete extraction of iron sulfide also occurs at considerably less sodium dicyclohexyldithiocarbamate consumption.
