Embodiment 1

[0025] The impact of the consumption of embodiment 1 auxiliary collector RC on rutile flotation effect

[0026] A rutile flotation collector composition is composed of main collector salicylhydroxamic acid and auxiliary collector RC. The auxiliary collector RC is prepared by the following method: water, kerosene and TX-100 (HLB: 13.4) are mixed at a mass ratio of 100:5:0.15 to obtain an oil-water mixture; the oil-water mixture is placed in a high-shear dispersing emulsifier Disperse in 10000r / min rotation speed for 10min to obtain rutile auxiliary collector RC.

[0027] The application of the rutile flotation collector composition in the rutile flotation of this embodiment specifically comprises the following steps:

[0028] (1) Preparation of rutile pulp: Add 3 g of rutile single mineral with a particle size of -74 to +38 μm and 90 mL of distilled water into a 100 mL hanging tank flotation machine, stir and adjust the slurry at a speed of 1080 r / min to obtain rutile pulp;

Abstract

The invention belongs to the technical field of rutile flotation, and particularly relates to a rutile flotation collector composition and application thereof. The rutile flotation collector composition is composed of a main hydroximic acid collector and an assistant RC collector. According to the application, a lead nitrate activator, the main hydroximic acid collector, the assistant RC collector and an MIBC frother are sequentially added in rutile flotation pulp, wherein before the next agent is added, stirring is carried out for 3 min every time after each agent is added; after all the agents are added, ventilated flotation is carried out; after flotation is finished, an obtained froth product and tailings in a flotation tank are respectively filtered, dried and weighed finally. According to the rutile flotation collector composition and the application thereof, on the basis of the hydroximic acid collector with good selectivity, the assistant RC collector capable of achieving a synergistic effect with hydroximic acid is added, so that the collecting capability of the agents is substantially improved, and the flotation recovery rate of rutile is effectively improved; meanwhile, the use amount of hydroximic acid is reduced, so that the agent cost for rutile flotation is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of rutile flotation, and in particular relates to a rutile flotation collector composition and application thereof. Background technique [0002] Rutile is the main raw material for smelting titanium metal, manufacturing titanium dioxide and welding flux for welding rods. Primary rutile ore is the main industrial type of rutile ore in my country, which accounts for 86% of the total reserves of rutile resources, while rutile placer is only 14%. At present, the rutile mines developed and utilized in my country are mainly seaside placer mines. The primary rutile mines in my country have not been developed and utilized on a large scale so far due to their low grade, fine particle size, complex mineral composition, poor selectability, and low recovery rate, resulting in a shortage of domestic rutile mine resources. situation. [0003] my country's rutile resources mainly exist in the form of eclogite, eclogite-t...
