Description

A kind of CHARACTERISTICS OF TAILINGS SAND ferro element choosing method again
Technical field
The present invention relates to a kind of CHARACTERISTICS OF TAILINGS SAND ferro element choosing methods again.
Background technique
Certain one factory of company's ore dressing is located to the east of Hami city, and dressing plant is put into operation for 1998, is constructed and put into operation within 2000, Ore-dressing technique uses three sections of broken, closed circuit screenings plus magnetic pulley dry type magnetic separation and stage grinding, the beneficiation combined method stream for first floating rear magnetic Journey.800,000 tons/year of raw ore of dressing plant year processing, product position are 400,000 tons of iron ore concentrate or so of 65%.It is tired to 2018 from going into operation Family planning produces 726.09 ten thousand tons of iron ore concentrate, arranges 580.87 ten thousand tons of Tailings total amount.2019 at about 1 kilometer of one factory east of ore dressing Two factory of ore dressing is built, is constructed and put into operation within 2010.Two factory and office of ore dressing reason raw ore is the finished product mine that certain mine has been crushed.Two factory of ore dressing adopts - three sections of cyclone classification-floatation desulphurization-two smart magnetic separation-concentrate concentrations-are regrinded with ore grinding-spiral classifier classification-thick magnetic separation- Filtering-Tailing thickening-filtering process flow, Tailings Dam and one factory of ore dressing share.Two factory of ore dressing is constructed and put into operation to 2017 certainly Tire out to about 448.82 ten thousand tons of Tailings Dam tailing disposal.Two factories add up to tailing disposal total amount to be 10,300,000 tons.Creation data over the years is aobvious Show, all iron content in one factory's tailing of ore dressing averagely reaches 16.5% or more, and magnetic iron content is higher than 2%, in two factory's tailing of ore dressing All iron content averagely reach 14.5 or more %, magnetic iron content is higher than 1.8%,.According to the mill tailings library tailing of completion Sand recycles experimental study report analysis, under the conditions of the current iron material market price, CHARACTERISTICS OF TAILINGS SAND iron content member in the Tailings Dam Element recycling value with higher.Through searching, the similar further resource utilization of Tailings sand of property is not found Developing example, it is no it is ready-made to the Tailings sand select again technique and technology for use for reference.
Summary of the invention
The purpose of the present invention is to provide a kind of CHARACTERISTICS OF TAILINGS SAND ferro element choosing methods again, using in this process Tailings Dam CHARACTERISTICS OF TAILINGS SAND after, can produce meet market quality requirement iron ore concentrate, finally realize that CHARACTERISTICS OF TAILINGS SAND further provides in the Tailings Dam Sourceization utilizes purpose.
The purpose of the invention patent is achieved in that a kind of CHARACTERISTICS OF TAILINGS SAND ferro element, and choosing method, operating procedure are as follows again: will Feed bin is poured by the CHARACTERISTICS OF TAILINGS SAND that Tailings Dam is fetched, feed wet drum sieve progress removing impurities object through feed bin lower belt transporter and is added Water causes ore pulp, and ore pulp uniformly feeds one section of high intensity magnetic separation and carries out preconcentration, and magnetic field strength: 0.4T, a stages of magnetic separation product are fed Cyclone carries out one section of classification, one section of classification qualified product, and material of -200 mesh contents greater than 85% feeds two stages of magnetic separation and carry out again Secondary essence magnetic separation, magnetic field strength: 0.15T, two sections of smart magnetic separation products feed progress thickening filtration after flotation device carries out desulfurization again and are formed Iron ore concentrate finished product;One section of classification sand setting feeds ball mill and regrinds, and ball mill ore discharging returns again to one section and is classified;One section of magnetic Choosing and the merging of two stages of magnetic separation tailings are discharged into Tailings Dam, and flotation of sulfur concentrate individually filters stacking.
Drilling or exploratory trench sampling are carried out in the Tailings Dam, ore dressing recycling test is carried out to representational sample and is ground Study carefully, according to research achievement and using existing advanced mineral processing technology and equipment build-up spoil reclaming factory to the iron member in CHARACTERISTICS OF TAILINGS SAND Element carries out industrial production recycling.A, it is divided into the 3 sampling regions A, B, C from West to East in the Tailings Dam, points 5 meters * 5 meters, 10 * 10 meters of rice, 15 meters * 15 meters are layouted, and carry out drilling or exploratory trench sampling, and be processed into comprehensive sample.B, chemistry is carried out entirely to comprehensive sample Analysis, it is found that it, for the mineral species of recycling, according to valuable mineral characteristic design experiment method and process and carries out whole process Many condition experimental study.C, Zai Xuan factory production technology is designed according to experimental study and carries out the building-up work of Zai Xuan factory, then selected Factory after debugging, defect elimination and external condition it is perfect, put into normal production.Plant tailing library ferro element selects process flow again again are as follows: The preparatory removing impurities pulping of a rotary screen → stages of magnetic separation enrichment → classification → ore grinding → bis- stages of magnetic separation → floatation desulphurization → filtering.
The present invention selects technology by using a kind of CHARACTERISTICS OF TAILINGS SAND ferro element of original creation again, and processing Hami is public The CHARACTERISTICS OF TAILINGS SAND in mill tailings library is taken charge of, the iron ore concentrate for meeting market quality requirement has been produced.The spoil reclaming factory is in 2014 Year formally building up trial throw produces, and by constantly improve for debugging, defect elimination and external condition, produces gradually direct motion, and 2014 to 2018 Year, about 8,200,000 tons of the spoil reclaming factory coprocessing CHARACTERISTICS OF TAILINGS SAND, 40.92 ten thousand tons of iron ore concentrate for producing Iron grade 63% create benefit Moisten 100,000,000 yuan or more, iron ore concentrate all carries out market-oriented sale.
Detailed description of the invention
Attached drawing 1 is process flow chart of the invention.
Specific embodiment
A kind of CHARACTERISTICS OF TAILINGS SAND ferro element choosing method again, as shown in Figure 1, operating procedure is as follows: the tailing that will be fetched by Tailings Dam Sand pours into feed bin, feeds wet drum sieve progress removing impurities object through feed bin lower belt transporter and water is added to cause ore pulp, ore pulp is equal It spares to and carries out preconcentration into one section of high intensity magnetic separation, magnetic field strength: 0.4T, a stages of magnetic separation product feed cyclone and carry out one section point Grade, one section of classification qualified product, material of -200 mesh contents greater than 85% feeds the progress of two stages of magnetic separation, and smart magnetic separation, magnetic field are strong again Degree: 0.15T, two sections of smart magnetic separation products feed after flotation device carries out desulfurization again and carry out thickening filtration formation iron ore concentrate finished product;One section Classification sand setting feeds ball mill and regrinds, and ball mill ore discharging returns again to one section and is classified;One stages of magnetic separation and two stages of magnetic separation tails Mine merging is discharged into Tailings Dam, and flotation of sulfur concentrate individually filters stacking.
