Problems solved by technology

[0004] Conventionally used floating titanium collectors mainly include oxidized paraffin soap, tall oil, oleic acid, arsenic-containing organic matter, etc., but the existing collectors used in flotation of ilmenite are either too expensive or suitable for The PH value range is narrow, or the stability of the flotation index is poor, and some of the collectors also contain toxic components, which will have adverse effects on ecology and environmental protection. The effect of flotation collection such as iron rutile is relatively poor, the amount of collector is large, the recovery effect is not ideal, and the recovery rate is low

Abstract

The invention discloses a collector for floating ilmenite and a preparation method thereof. The collector is mainly prepared from the following components by mass percent: 40-60% of peroxide fatty acid soup, 5-15% of emulsifiers, 10-30% of oil substance and the balance of water. The preparation method comprises the following steps: mixing the components uniformly according to the mass percent ratio, throwing the mixture into a reaction kettle and stirring the mixture for 0.5-1 hour, thus obtaining the collector. The collector has the advantages of small amount, low cost, strong collecting capability, safety, nontoxicity, capability of reducing the amount of media such as modifiers.

Description

technical field [0001] The invention relates to an ore dressing agent and a preparation method thereof, in particular to a collector for flotation and a preparation method thereof. Background technique [0002] The gangue minerals of fine-grained\fine-grained ilmenite and titanium-ferrorutile mainly include magnetite, titanopyroxene, plagioclase, hornblende, pyrite, pyrrhotite and other minerals. The selected raw ore has a finer particle size and is a refractory mineral. The commonly used beneficiation process for fine-grained ilmenite is: strong magnetic-flotation process, that is, use a strong magnetic machine to enrich the ilmenite grade in advance, desliming, and then flotation for recovery. [0003] At present, the technological process of ilmenite flotation is basically to float sulfur first, and then float titanium. election and one-time scavenging flotation ilmenite), the flotation concentrate grade must be greater than 47%. [0004] Conventionally used floating t...
