Problems solved by technology

Among them, flotation is mainly used for the selection of particle size of -0.074mm, which has defects such as large consumption of chemicals, serious environmental pollution, complicated operation and high cost; electric separation is mainly used for selection of particle size of +0.047mm, and there are time-consuming processing Small capacity, a certain temperature (about 80°C) requirement for the selected materials, high power consumption, and potential safety hazards; as a selection, different models can be selected according to requirements to adapt to a wider particle size range, but there are Disadvantages such as small processing capacity, large occupied area, high water consumption and low yield

Embodiment 1

[0027] The present embodiment is that the production process of primary ilmenite ore of the present invention is used to process inclined plate grit (TiO 2 content is 9%). The particle size of the raw material is +0.074mm, and the aforementioned tailings TiO 2 Pre-enriched to 25%, dried, and then selected by a permanent magnetic dry drum magnetic separator (magnetic field strength is 0.7T) to obtain TiO 2 Qualified titanium concentrate with a content of 47.5%, final tailings TiO 2 The content is 5.4%.

Embodiment 2

[0029] The present embodiment is that the production process of primary ilmenite ore of the present invention is used to process the inclined plate overflow (TiO 2 content is 10%). The particle size of the raw material is +0.074mm, and the aforementioned tailings TiO 2 Pre-enriched to 20%, dried, and then selected by a permanent magnetic dry drum magnetic separator (magnetic field strength is 0.9T), to obtain TiO 2 Qualified titanium concentrate with a content of 48.2%, final tailings TiO 2 The content is 6.1%.

Embodiment 3

[0031] This embodiment is that the production process of the selected titanium concentrate of the present invention is used to process the spiral middle ore (TiO 2 content is 27%). The raw material is directly dried, and then selected by a permanent magnetic dry drum magnetic separator (the magnetic field strength is 0.7T) to obtain TiO 2 Qualified titanium concentrate with a content of 47.8%, final tailings TiO 2 The content is 4.80%.

Abstract

A technology for dressing the primary ilmenite includes removing Fe component, coarse separating for enriching TiO2 to more than 20%, drying, and fine dressing by permanent-magnet drum-type separator to enrich TiO2 to more than 47%.

Description

Technical field [0001] The invention relates to a beneficiation process, in particular to a beneficiation process of titanium concentrate. Background technique [0002] At present, the beneficiation of primary ilmenite at home and abroad is mainly through weak or medium magnetic (2000-3000mT) iron removal and then re-election or strong magnetic separation to remove TiO 2 Enriched to more than 20%, then use flotation, electric separation or shaker as a selection to obtain the final qualified product (TiO 2 Titanium concentrate with a content of not less than 47%). Among them, flotation is mainly used for the selection of particle size of -0.074mm, which has defects such as large consumption of chemicals, serious environmental pollution, complicated operation and high cost; electric separation is mainly used for selection of particle size of +0.047mm, and there are time-consuming processing Small capacity, a certain temperature (about 80°C) requirement for the selected mater...
