Problems solved by technology

Therefore, in the production process of potassium sulfate, the effect of the production process depends on the transformation degree of all sylvite minerals to langbeinite, however, because the sylvite mixed salt obtained after drying out sodium chloride in the halite pool only contains A small amount of potassium minerals, the potassium content is only 4-7%. Unless the impurities are removed, the recovery rate of the concentrator will be very low. Since 1970, anion flotation has been used to improve the grade of low-grade mixed salt , making the grade of potassium therein reach or be higher than 12%, it has just become a generally adopted production method in the potassium sulfate production process. Sodium alkyl sulfonate, but the quality of the low-grade mixed salt flotation by sodium dodecyl sulfonate has always been very low, specifically manifested in the low potassium ion content, high chloride ion content, high impurity content and low beneficiation efficiency

Abstract

The invention discloses a combined organic sodium sulfonate salt flotation agent, which consists of the following components in percentage by weight: 50-90 percent of alkyl sodium sulfonate, 7-30 percent of sodium dodecyl benzene sulfonate and 3-20 percent of butyl sodium naphthalenesulfonic acid. The combined organic sodium sulfonate salt flotation agent can contribute to remarkably enhancing the quality of a low-grade mixed salt, and has short floatation time and high floatation efficiency.

Description

technical field [0001] The invention relates to a foam separation agent for chemical mining and metallurgy, which is applied to the production field of potassium magnesium sulfate flotation or langbeinite flotation, in particular to a combined organic sulfonic acid sodium salt flotation agent. Background technique [0002] There is a process for producing potassium sulfate, which is to first dry out sodium chloride in the rock salt pond to obtain the mixed salt of potassium magnesite. These mixed salts are composed of rock salt (NaCl), epsom salt (MgSO4 7H 2 O), langbeinite (MgSO 4 ·K 2 SO 4 ·6H 2 O), langbeinite (MgSO 4 ·K 2 SO 4 ·3H 2 O) and carnallite (MgCl 2 ·KCl·6H 2 O) composition, and then the langbeinite is separated by flotation, and then the high-grade concentrate obtained is easily converted into potassium sulfate by conventional processing technology. Therefore, in the production process of potassium sulfate, the effect of the production process depends...
