本专刊提出了用泡沫浮选法处理铅、铀与稀土类型矿物和矿石的方法及浮选药剂。此法特点是使用了具有下述化学通式的叔胺型浮选药剂。式中R——碳原子数约为6～24的脂族烃基; A——碳原子数约为2～4的氧烯基; X——氢或羟基; m——从0约至10范围内的数值; n_1——从1约至4范围内的数值; n_2——为1,2,或3。 x——从0约至4范围内的数值; y——为0或1; m+y总数为1至11,其盐亦同; 这种方法尤其适用于硫化和氧化矿石与矿物的浮选。 This special issue presents methods and flotation reagents for the treatment of lead, uranium and rare earth minerals and ores using froth flotation. This method is characterized by the use of a chemical formula has the following tertiary amine type flotation reagent. Wherein R is an aliphatic hydrocarbon group having a carbon number of about 6 to 24, A is an oxyalkylene group having a carbon number of about 2 to 4, X is hydrogen or a hydroxy group, m is from about 0 to about 10 N_1 - a value ranging from 1 to 4; n_2 - is 1, 2, or 3; x is a number ranging from 0 to 4; y-- is 0 or 1; the sum of m + y is from 1 to 11 and the salts thereof are also the same; this method is particularly suitable for sulfurizing and oxidizing flotation of ores and minerals .
