Problems solved by technology

[0003] However, due to the nature of oleic acid, the existing oleic acid collectors often have the disadvantages of poor solubility, poor selectivity and resistance to hard water, and can only act on slurry with a temperature not lower than 14 degrees Celsius , thus greatly reducing the efficiency and quality of desliming

Abstract

The invention discloses a fine silt collecting agent for achieving desliming through flotation. The fine silt collecting agent comprises 1-4 parts of sodium hexadecyl sulfonate, 1-4 parts of stearic acid polyoxyethylene ether, 1-2 parts of sodium linoleate and 1-2 parts of a mahogany petroleum sulfonate mixture. A using method of the fine silt collecting agent sequentially comprises the steps that firstly, ore raw materials are prepared, the fine silt collecting agent is manufactured, flotation of fine silt is carried out, and finally desliming of ore pulp is carried out. The method has the beneficial effects that the mahogany petroleum sulfonate mixture is added on the basis of the original formula, the mahogany petroleum sulfonate mixture is an anionic surfactant and is also a high-quality surfactant, and the mahogany petroleum sulfonate mixture is compounded with the hexadecyl sodium sulfonate and the stearic acid polyoxyethylene ether, so that the interfacial tension of ore pulp can be reduced, the desliming efficiency can be better improved, and the molecular weight can also influence the relative solubility between the sodium linoleate and water, and also influence the hydrophobicity and hydrophilicity, so that the dispersity and solubility of the collecting agent are improved, and the desliming capacity is further enhanced.

Description

technical field [0001] The invention relates to a collector, in particular to a fine-sludge collector that realizes desliming through flotation, and belongs to the technical field of desliming. Background technique [0002] Desliming is the process of separating fine slime and coarse sand in the ore pulp during beneficiation. At present, the two main desliming methods are magnetic separation and flotation. Surfactant-foaming agent is used to adsorb the fine mud in the pulp to the surface, so as to facilitate desliming. The existing collectors are widely used in the flotation of different substances, and are widely used in the desliming of mineral pulp. The main scavenger is oleic acid. [0003] However, due to the properties of oleic acid, the existing oleic acid collectors often have the disadvantages of poor solubility, poor selectivity, and poor resistance to hard water, and can only act on slurries with a temperature of not lower than 14 degrees Celsius. , thereby grea...
