Description
Technical field
The present invention relates to technical field of mineral processing, are related to a kind of side for recycling garnet and omphacite in Ryukyu Currents
Method.
Background technique
Eclogite is a kind of high temperature and pressure metamorphic rock, and part Su Lu superelevation is prolonged in China Qinling Mountains-Dabie UHPM zone east
A large amount of ultrahigh pressure eclogite bodies are distributed in pressure modifier band.The mineral composition of the Ryukyu Currents of different sources is different, mainly by
The mineral compositions such as garnet, omphacite, chlorite, wherein the mineral content of garnet and omphacite is total can generally reach
80% or more, the mineral that can be also comprehensively utilized containing rutile, kyanite, mica etc. in the Ryukyu Currents in the part place of production.
The main dressing product of Ryukyu Currents is garnet and omphacite.Garnet is sharp with grain corner, compares
Weight and the features such as hardness is larger, chemical property is stablized, be widely used in steel derusting by sandblasting, high pressure waterjet, wear-resistant material preparation,
The industrial circles such as chemical industry and Water treatment filtration, good garnet are alternatively arranged as jewel；Omphacite also has part and pomegranate
The similar property of sub- stone, the partial use of alternative garnet, while omphacite color is gorgeous, can be used as building decoration material
Material.With the fast development of national economy, the market demand of garnet and omphacite also increasingly increases.
Currently, the method for garnet and omphacite mainly uses single gravity treatment and flotation in recycling Ryukyu Currents.Just
For single gravity concentration process, it is more difficult to the garnet and omphacite concentrate product of mineral content high (> 90%) are obtained, it is main former
The gravitational separation equipments sharpness of separation such as spiral chute, shaking table is not high because being, and in ore milling product wholegrain grade reuse adoption process thickness ore particle it
Between interfere with each other it is serious.The sharpness of separation of floatation process is higher than single gravity concentration and magnetic separation process, but there are costs for floatation process
The control of higher, flotation conditions is strictly not easy to implement at the scene, floating agent pollution environment, garnet and omphacite concentrate surface
There is medicament residual.The weak magnetic that garnet has is sorted according to single magnetic separation, then due to garnet with
The magnetic difference of other mineral is smaller, and effect is poor.
Certain Eclogite Type rutile ore roughing experimental study [J], nonmetallic ore, yellow person of outstanding talent Wei etc., 2017.1,40 (1) are open
A kind of rutile ore roughing test method obtains light mineral directly as omphacite concentrate, but green after table concentration
The index of pyroxene concentrate is poor, yield 26.06%, and mineral content is greater than 85%, mineral recovery rate 70%, in addition, the party
The yield 26.05% of garnet concentrate, mineral content 90%, mineral recovery rate 70% in method.Garnet and omphacite
Yield, mineral content and the mineral recovery rate of concentrate all need to be further increased.
Summary of the invention
The present invention is directed to overcome prior art defect, garnet and omphacite in a kind of recycling Ryukyu Currents are proposed
Method, this method can effectively improve the quality of garnet and omphacite concentrate, and garnet yield is improved, mine
Object content is greater than 91%, and mineral recovery rate is greater than 85%；Omphacite concentrate Omphacite mineral content is greater than 90%, omphacite mine
