Description
Technical field
The present invention relates to a kind of scheelite normal temperature flotation methods, belong to technical field of mineral processing.
Background technique
Being the discovery that earliest at the beginning of the eighties in 18th century for wolfram element, is strangled by Sweden's science homestead and is found in scheelite, away from
The present existing more than 200 years history.For China's tungsten ore based on scheelite, scheelite is also known as " scheelite ", there is metallic luster but not
With magnetism, color is brown or faint yellow when impure.When dissociation, fracture is in irregular shape.Deposit type is mainly thready pulse leaching
Dye type and Skarn-type, Skarn-type scheelite stone form is mostly lenticular, and like stratiform and cryptomere, ore disseminated grain size is thin and product
Position is lower.Its industrial use is mainly used for refining tungsten, manufacture wolfram steel etc..
Tungsten Deposits In China is resourceful, and wherein scheelite accounts for about the 71% of tungsten ore total amount.Current scheelite to sort mode main
It is normal temperature flotation and heating flotation.Flotation is heated due to energy consumption height, the problems such as complex process forces people constantly to deepen dialogue tungsten
The research of mine float test under normal temperature conditions.The difficult point that sorts of scheelite under normal temperature conditions essentially consists in itself and fluorite, side
The calcium salts class gangue mineral such as Xie Shi efficiently separates, and in floatation process, and the effect of floating agent is to sorting result to closing weight
It wants.The floating agent type of scheelite is more at present, includes anionic collector, cation-collecting agent, chelating for collecting agent
Class collecting agent etc..In practical application, most of collecting agent is since the factors such as poor selectivity make flotation effect unsatisfactory
This, changes floatability difference between mineral, or improve sorting result using combination medicament by the way of adding inhibitor, because
And the development for developing the strong collecting agent of selectivity is scheelite main direction of studying.
Summary of the invention
The present invention is for there are medicament poor selectivity and needing to heat flotation energy consumption height etc. and ask in existing Scheelite Flotation
Topic, provides a kind of scheelite normal temperature flotation method, has the spy that low energy consumption, selectivity is good using this method Scheelite Flotation mine
Point, when flotation, which only needs to add a small amount of inhibitor, can obtain ideal separating effect, this method dialogue tungsten at normal temperature
Mine has preferably selectivity, can obtain preferable WO using this method3Recovery index.
Raw ore ore grinding to -0.074mm is first accounted for 50% ~ 90%, water is added to be configured to mine by a kind of scheelite normal temperature flotation method
Slurry, is adjusted to 8 ~ 10 for slurry pH, then adds combined capturing and collecting agent 50g/t ~ 500g/t, inflates and scrapes foam to obtain tungsten
Concentrate.
The combined capturing and collecting agent is isopropyl alkyl phosphonic acids, neopelex, N- myristoyl base aminobutyric acid
Mixture, wherein the mass percent of isopropyl alkyl phosphonic acids is 10 ~ 50%, and the mass percent of neopelex is
The mass percent of 10 ~ 50%, N- myristoyl base aminobutyric acid is 10 ~ 50%, and the mass percent of three is 100%.
Inhibitor waterglass 0.5kg/t ~ 10kg/t is also added before adjusting pH value.
The pH value is adjusted using sodium carbonate.
The present invention has the following advantages and beneficial effects:
1, the combined capturing and collecting agent used in the present invention is respectively isopropyl alkyl phosphonic acids, neopelex, N- myristoyl base
Aminobutyric acid is all conventional dose, is easy to get, cheap.
2, when using Scheelite Flotation mine of the present invention, combined capturing and collecting agent has stronger selectivity to scheelite, when flotation without
Need to add or add a small amount of inhibitor can obtain ideal separating effect.
3, the present invention has preferable flotation effect to scheelite at normal temperature, does not need subsequent heating flotation circuit,
Process flow is simple, less energy consumption, and production cost is low.
