Intensification of potash ore flotation process by the introduction of hydrophobizator into the potassium chloride collective mixture

Abstract

The process of enrichment of potash ore using industrial oils as a hydrophobizing agent in the collective mixture of potassium chloride, which is a composition of salts of higher aliphatic amines, pine oil and polyethylene glycol PEG- 400, has been investigated. A comparative analysis of the influence of industrial oils I-8A, I-12A, I-30A and liquid paraffins on the technological parameters of potash ore flotation has been carried out. The influence of hydrophobizing additives on the adsorption of amine on potassium chloride crystals was investigated by infrared spectroscopy. It has been established that the introduction of industrial oils into the flotation system ensures the recovery of potassium chloride at the same level as when using a collective mixture with liquid paraffins. The best flotation performance when using industrial oils is possible by increasing the consumption of the apolar reagent.

“…При отделении сильвина от каинита наиболее эффективными собирателями являются амины с короткоцепочечным алкильным радикалом, вторичные или замещенные первичные амины, гидрохлоридные или ацетатные соли аминов. В технологии переработки полигалитовых руд методом обратной флотации в качестве собирателя хлорида натрия (галита) используют циклический амин (алкилморфолин) [1][2][3][4].…”
