Abstract

The invention discloses a quartz sand flotation agent removal method. The invention relates to the technical field of quartz sand processing. Based on the problem that agents are adsorbed on the surface of floated quartz sand, the method comprises the following steps that (1) performing agent adding and scrubbing, specifically, the floated quartz sand is taken, a mixed agent is added, the mass ratio of the quartz sand to the mixed agent is 1: 2, the mixed agent comprises ammonia water and absolute ethyl alcohol, the mass ratio of the ammonia water to the absolute ethyl alcohol is 1: 1-5, and centrifugation is conducted after scrubbing; (2) cleaning with hot pure water; (3) calcining, specifically, calcining the quartz sand centrifuged in the step (2) at the temperature of 290-400 DEG C for5-10 minutes; (4) performing water quenching; (5) performing ultrasonic cleaning; and (6) heating. The method has the beneficial effects that the method is simple in technical process, energy-saving,environment-friendly and thorough in agent removal, the used agent is free of metal cations, and secondary pollution is avoided.

Description

technical field [0001] The invention relates to the technical field of quartz sand processing, in particular to a quartz sand flotation drug removal method. Background technique [0002] Due to its unique physical and chemical properties, high-purity quartz sand plays a pivotal role in industries such as national defense, electronics, machinery and IT. With the development of science and technology, the demand for high-purity quartz sand in the above industries is increasing. [0003] The production of high-purity sand generally adopts a combined process of strong magnetic-pickling-flotation. Collectors such as sodium petroleum sulfonate, oleic acid, and mixed amines are used in flotation. Patent CN201610419797.8 discloses a quartz mineral purification flotation The composition contains the following components according to the percentage of parts: 20%-30% of compound amine, 30%-40% of sodium petroleum sulfonate, 5%-10% of hydroxamic acid and 30%-40% of industrial alcohol ...
