Abstract
The beneficiation method of fluorite is reclaimed in a kind of white tungsten rough concentrate of the present invention, fluorite recovery technical field of beneficiation is reclaimed in more particularly to white tungsten rough concentrate, successfully solve that Luoyang Luanchuan Area skarn type scheelite bed Associated Fluorite grade is low, is difficult to the problem that reclaims, obtain good economic benefit and social benefit.Using white tungsten rough concentrate preconcentration-preconcentration mine tailing fluorite flow, it is 93.02% that can obtain grade, and the rate of recovery is 41.76% fluorite concentrate.Calcite grade is 3.68% in fluorite concentrate, and the loss late of tungsten is only 0.344%.
Description
Technical field：
The present invention relates to fluorite technical field of beneficiation, the beneficiation method of fluorite is reclaimed in especially a kind of white tungsten rough concentrate.
Background technology：
Skarn type scheelite bed, containing substantial amounts of quartz, it is associated with a certain amount of calcium carbonate, fluorite etc., but the product of fluorite
Position is not general high, does not reach the economic balanced grade of comprehensive reutilization.The scheelite of Luoyang, henan city Luanchuan Area is typical silicon
Card lithotype mineral deposit, the day processing of white tungsten flotation reach 50000 tpds, and fluorite grade is between 7%-10% in raw ore, and grade is too
It is low, always can not comprehensive reutilization.Wherein in white tungsten rougher process, the grade of fluorite is enriched with and is enriched with also with white tungsten,
The grade of fluorite is 28%-30% in white tungsten rough concentrate, and there is very high recycling to be worth.
The content of the invention：
Above-mentioned in order to overcome the shortcomings of, the invention provides the beneficiation method that fluorite is reclaimed in a kind of white tungsten rough concentrate.
The technical solution adopted for the present invention to solve the technical problems：
The beneficiation method of fluorite is reclaimed in a kind of white tungsten rough concentrate, is comprised the following steps：
Firstth, white tungsten rough concentrate preconcentration flotation
Inhibitor waterglass 3000-4000g/t is added in white tungsten rough concentrate, carries out white tungsten preconcentration；
White tungsten preconcentration concentrate enters white tungsten heating concentration, and white tungsten preconcentration mine tailing enters fluorite；
Secondth, preconcentration mine tailing fluorite
White tungsten preconcentration mine tailing adds collecting agent NAK550-650g/t, obtains fluorite rough concentrate；
Fluorite rough concentrate is carried out successively ten times it is selected, ten times it is selected in sequentially add inhibitor acidified sodium silicate 800-1000g/
t、800-1000g/t、650-800g/t、650-800g/t、500-650g/t、400-500g/t、400-500g/t、400-
500g/t, 300-400g/t, 200-300g/t, add inhibitor ATM100-150g/t, 100-120g/t, 80-120g/t, 60-
80g/t、50-60g/t、40-50g/t；、30-40g/t、20-30g/t、10-20g/t；, 10-20g/t, fluorite mine tailing X and
First time fluorite cleaner tailings and second of fluorite cleaner tailings return to white tungsten roughing together；
Third time fluorite cleaner tailings to the tenth fluorite cleaner tailings carries out tentatively taking off tungsten processing together, and adds ATM40-
60g/t, do further flotation；
Fluorite chats M is returned into white tungsten heating concentration, it is selected that concentrate returns to third time fluorite.
Due to using technical scheme as described above, the present invention has following superiority：
The beneficiation method of fluorite is reclaimed in a kind of white tungsten rough concentrate of the present invention, successfully solves skarn type scheelite
Bed Associated Fluorite head grade is low, is difficult to the problem that reclaims, obtains good economic benefit and social benefit.
Brief description of the drawings：
Fig. 1 is the flow chart of the present invention.
Embodiment：
The present invention can be explained in more detail by example below, the open purpose of the present invention is intended to protect in the scope of the invention
All changes and improvements, the invention is not limited in the following examples；
The beneficiation method of fluorite is reclaimed in a kind of white tungsten rough concentrate, is comprised the following steps：
Firstth, white tungsten rough concentrate preconcentration flotation
Inhibitor waterglass 3500g/t is added in white tungsten rough concentrate, carries out white tungsten preconcentration；
White tungsten preconcentration concentrate enters white tungsten heating concentration, and white tungsten preconcentration mine tailing enters fluorite；
Secondth, preconcentration mine tailing fluorite
White tungsten preconcentration mine tailing adds collecting agent NAK600g/t, obtains fluorite rough concentrate；
Fluorite rough concentrate is carried out successively ten times it is selected, ten times it is selected in sequentially add inhibitor acidified sodium silicate 900g/t,
900g/t, 700g/t, 700g/t, 600g/t, 450g/t, 450g/t, 450g/t, 350g/t, 250g/t, add inhibitor
