Abstract
The present invention discloses a floatation method of whole grade ilmenite. The method comprises the following procedures: gangues are utilized as raw material after the selection of iron with vanadium titano-magnetite, and beta TiO<2> 17% to 19% crude titanium ore concentrate is obtained after the discarding tail by a first section of high magnetism of which the magnetic field intensity is 1300 amperes; then the crude titanium ore is milled in a closed circuit; through the iron sweeping with weak magnetism, the qualified products enter a second section of high magnetism of which the magnetic field intensity is 750 amperes, and then beta TiO<2> 22% to 24% titanium ore concentrate is obtained; then after the work of reverse flotation desulfurization, the gangues enter the work of floatation method of whole grade ilmenite, and the titanium ore concentrate of which the metal recovery rate is 34% to 36% is produced. The present invention has the advantages of short flow, low investment, high metal recovery rate, and easy control of production, which reduces the cost of production operations and creates good economic benefit for enterprises.
Description
Technical field
The present invention relates to from iron tailings of low-grade vanadium titano, reclaim the production technology of ilmenite, be specifically related to a kind of floatation method of whole grade ilmenite.
Background technology
In the prior art, the ilmenite ore dressing mainly contains following several method:
1, gravity treatment-flotation combined flow process: this technology is difficult to control to the ilmenite grade fluctuation that enters flotation operation, and mine-supplying quantity instability, worker's operation easier is big, and the ilmenite metal recovery rate is generally on the low side, and the metal recovery rate of iron selection tailings is generally had only 12～14%.
2, climb the used technological process of production of steel mining industry Co., Ltd: be about to+the 0.10mm grade adopts the technological process of gravity treatment-electric separation to sort;-0.10mm adopts one section strong magnetic-flotation process to sort, and its metal recovery rate can only reach 20～22%, and the technological process complexity, and equipment investment is bigger, the processing charges height; Especially electric separation, worker's operating environment is relatively poor, and dust is bigger, and operation easier is big.
Panxi Diqu has abundant v-ti magnetite ore resources, especially TiO in Taihe county iron ore iron selection tailings
2Content up to 11～12%, the useful resources that how comprehensively to reclaim in the vanadium titano-magnetite is that one of ordinary skill in the art have problem to be solved always.
Summary of the invention
At the prior art above shortcomings, the purpose of this invention is to provide and a kind ofly can not only simplify technological process, realize the flotation of wholegrain level, and the metal recovery rate height, stable equipment operation is reliable, and ilmenite wholegrain level easy and simple to handle sorts new method.
The object of the present invention is achieved like this: floatation method of whole grade ilmenite comprises the steps:
1) utilize mine tailing behind the vanadium titano-magnetite iron as raw material, through one section magnetic field intensity be after the strong magnetic of 1300 peaces are thrown tails β TiO
217～19% crude titaniferous concentrates;
2) thick titanium ore is carried out one section closed circuit grinding, qualified products are swept iron through weak magnetic, and entering two sections strong magnetic magnetic field intensities is 750 peaces, obtains β TiO
222～24% ilmenite concentrates;
3) after reverse flotation sulphur removal operation, mine tailing enters the floating titanium operation of wholegrain level, and main medicament is R-2 and sulfuric acid, behind the sorting operation through thick four essences, can obtain titaniferous more than 47.00%, metal recovery rate can reach 34～36% ilmenite concentrate, is the finished product ilmenite concentrate after the ilmenite concentrate drying.
The present invention has realized the problem of wholegrain level flotation ilmenite concentrate from the iron selection tailings of vanadium titano-magnetite, and its flow process weak point, reduced investment, metal recovery rate height reduce the production and operation cost, create favorable economic benefit to enterprise.
Compared to existing technology, the present invention also has following advantage:
1, this dressing method is the TiO in the iron selection tailings that rationally and will to greatest extent comprehensively reclaim vanadium titano-magnetite from now on
2, rational technology is provided and has sorted flow process.
2, adopt Derrick high frequency fine screen and ball mill to form the overground phenomenon that closed circuit classification can reduce ore.
3, this dressing method adopts two sections strong magnetic operations, makes the ilmenite concentrate grade reach 22～24% and enters flotation operation again.
4, flotation operation adopts the flotation of wholegrain level, and technology is simple, flow process is short, reduced investment, production cost are low, produce and be easy to control.
5, this dressing method has characteristics such as constant product quality, rate of recovery height.
Description of drawings
Fig. 1 is a process chart of the present invention.
The specific embodiment
Referring to Fig. 1, ilmenite of the present invention sorts the new method flow process and is:
1, utilize mine tailing behind the vanadium titano-magnetite iron as raw material (TFe10～13%, β TiO
211～13%), after being 1300 peaces, throwing tail, one section strong magnetic (Slon φ 1750) magnetic field intensity can get titanium β TiO
217～19% crude titaniferous concentrate;
2, thick titanium ore is carried out one section closed circuit grinding (1 of φ 2721 grate ball mill, 2 of high frequency fine screens), qualified products are swept iron through weak magnetic, and entering two sections strong magnetic (Slon φ 1750) magnetic field intensity is 750 peaces, can obtain β TiO
222～24% ilmenite concentrates;
3, after reverse flotation sulphur removal operation (main medicament is an xanthate), sulphur removal operation mine tailing enters the floating titanium operation of wholegrain level, main medicament is R-2 (the plain speech in Chengdu, Sichuan Science and Technology Ltd. produces) unit consumption (with respect to titanium ore) 5.64kg/T and 10% sulfuric acid unit consumption (with respect to titanium ore) 5.64kg/T, behind the sorting operation through thick four essences, can obtain titaniferous more than 47.00%, metal recovery rate can reach 34～36% ilmenite concentrate, is the finished product ilmenite concentrate after the ilmenite concentrate drying.Simultaneously, the concentrate of sulphur removal operation can obtain to contain the cobalt sulphur concentrate of Co 〉=0.30% through flotation repeatedly.
The present invention is the ore-dressing technique new technology that iron tailings of low-grade vanadium titano comprehensively reclaims ilmenite, and is artificial Factor affecting is little, and pulp granularity, concentration are had stronger adaptability, and processing charges are low, and it is short to have flow process, Reduced investment, the metal recovery rate height reduces the characteristics such as costs of production and operation, especially is fit to the ilmenite ore dressing and does Already.
