Technical Field

The invention relates to the field of flotation agents, in particular to a potassium ore flotation agent.

Background

Soluble potassium salt resources are main raw materials for producing potassium fertilizers and other potassium salt products, and play an extremely important role in industrial and agricultural production. The flotation method is one of the main methods for producing potash fertilizers, and about 80 percent of KCl is obtained from flotation production all over the world. In the flotation process, a flotation reagent is a key and directly determines the quality of a flotation index. Most of the existing potassium ore flotation agents are high in cost, and the quality of products is not satisfactory.

Disclosure of Invention

the invention provides the potassium ore flotation reagent by selecting reasonable component combination and the proportion among the components, and the potassium ore flotation reagent can obtain the flotation potassium ore with better quality and reasonably control the cost.

In order to achieve the purpose, the invention provides a potassium ore flotation reagent which comprises the following components in percentage by weight: 40-45% of acetate, 20-25% of polyalcohol mixture, 10-15% of OP-10, 5-10% of methyl silicone oil and 10-20% of extraction oil. Wherein, the acetate is primary amine acetate of multi-group differentiation and primary amine amidation from micromolecule primary amine to macromolecule primary amine, namely primary amine is firstly mixed, and then the mixed primary amine reacts with acetic acid to obtain a product, specifically,

The multi-group differentiation from micromolecular primary amine to macromolecular primary amine means that the primary amine raw material is C₈-C₂₂The mixed primary amine composed of primary amines with different carbon chains according to a certain proportion comprises the following components in percentage by weight: c₈5-15% of primary amine; c₁₂Primary amine: 5 to 10 percent; c₁₆Primary amine: 15 to 30 percent; c₁₈Primary amine: 50-60 percent; c₂₀Primary amine: 3 to 5 percent; c₂₂5-10% of primary amine.

Amidation of primary amine: and (3) reacting the mixed primary amine with acetic acid, and further dehydrating acetate to generate an amide product. The amidation proportion of primary amine is 10-20%.

Further, the polyalcohol mixture is butanol, octanol and pentanol which are mixed according to the weight ratio of 1:1: 1.

Further, the extraction oil contains C₄-C₈The hydrocarbon material of (1).

Further, the weight ratio of the composite material comprises: 40% acetate, 20% polyol mixture, 15% OP-10, 5% methyl silicone oil and 20% extraction oil.

Further, the weight ratio of the composite material comprises: 45% of acetate, 25% of polyol mixture, 10% of OP-10, 10% of methyl silicone oil and 10% of extraction oil.

Further, the extraction oil contains C₆-C₈The hydrocarbon material of (1).

Further, the extraction oil comprises 1, 3-butadiene.
