Abstract

Five derivatives of neopentanoic acid hydrazide were studied and their physicochemical properties (solubility, protolytic equilibria, hydrolytic stability), which determine the possibility of using reagents in the flotation processes of concentrating non-ferrous metals, were characterized. The composition of the complex compounds of the reagents with Cu(II), Ni(II), and Co(II) in solutions was found, their instability constants were calculated, as well as the solubility products of the preparatively isolated and identified complexes. The fundamental possibility of employing reagents as collectors is shown on the example of flotation of sulfide copper-nickel and copper ores.

新戊酸酰肼衍生物作为有色金属浮选回收剂的研究

摘要

研究了新戊酸酰肼的五种衍生物，并对它们的理化性质（溶解度、质子分解平衡、水解稳定性）进行了表征，这些性质决定了在有色金属的浮选过程中使用试剂的可能性。发现了溶液中试剂与 Cu(II)、Ni(II) 和 Co(II) 的络合物的组成，计算了它们的不稳定性常数，以及制备分离和鉴定的络合物的溶度积。以硫化铜镍和铜矿石浮选为例，说明了使用试剂作为捕收剂的基本可能性。
