Description
Technical field
The present invention relates to a kind of processing method of the low-grade tailing containing rubidium, more particularly to a kind of fine grinding-flotation-roasting-
Leaching is combined the low-grade tailing containing rubidium of processing, and the technique for realizing sorting, the enrichment, recycling of rubidium oxide belongs to tailings glass
Technical field.
Background technology
Rubidium is a kind of rare distributed metallic element.In recent years, with domestic and international aerospace industry, atomic energy industry,
The development of the new high-tech industries such as bioengineering and the energy, rubidium and its compound are with its exclusive characteristic, research for application and development
It receives significant attention.The application of developed country's rubidium is concentrated mainly on high-tech area, has 80% rubidium to be used to develop new and high technology,
Only 20% rubidium is used for traditional application field.With the development of industry, the demand of rubidium also gradually rises, and its value also by
Gradually highlighted.It reports and shows according to correlation study, price soars all the way rubidium metal since two thousand four, to rubidium metal at 2011
Price already reaches 1400000 yuan/kilogram.
The development of national economy can consume a large amount of raw material, and provided by mineral resources in the supply of raw material and be more than
50%.Mineral resources largely develop and use while will produce a large amount of tailing, not only need to occupy greatly if directly abandoning tailing
Soil is measured, causes prodigious destruction to the ecological environment of surrounding, and to put into considerable processing and maintenance cost.Rubidium element
Part is present in salt lake bittern, and part association is in various silicates ores.The machine of rubidium oxide in association type ore containing rubidium
It is 0.1% or so to select minimum industrial cutoff grade, at present to low-grade ore containing rubidium, is carried to the enrichment of rubidium especially from tailing
Take research seldom.The method that rubidium is recycled from association type ore containing rubidium or tailing containing rubidium is mainly straight with roasting, leaching and precipitation etc.
The method of connecing property is extracted, and the research that progress rubidium extraction on the basis of obtaining concentrate containing rubidium is enriched with based on sorting is less.To in ore
Rubidium first carries out beneficiation enrichment and is conducive to improve utilization rate of equipment and installations, reduces cost, is also beneficial to the efficient selective of downstream leachate
Separation.Therefore, a kind of process integration of beneficiation enrichment-leaching based on the tailing containing rubidium of exploitation carries out recycling and the profit of rubidium in tailing
With can make full use of mineral resources, expand mineral resource utilization range, extend mine life.
The more difficult enrichment of low-grade tailing containing rubidium, method is based on directly extracting, including the direct acid-hatching of young eggs and roasting are soaked
Go out, impurity ion content high leaching night will produce with direct extracting mode, cause to isolate and purify difficulty, products obtained therefrom purity and
The problems such as yield is low.
In conclusion the important application of scarcity, various aspects based on rubidium resource and the certainty of tailings glass, exploitation
A kind of technique from synthetical recovery rubidium metals resources in tailing containing rubidium not only has the economic values such as great development and application, but also can subtract
The ecological risk of few extensive Tailings Dam.The present invention specifically addresses golden from efficiently concentrating, sorting and extraction rubidium in tailing containing rubidium
The related process problem for belonging to resource, promotes the efficient utilization of resource.
