Description
Technical field
The present invention relates to a kind of secondary slimes of lode gold ore and rough just separating flotation technique, belong to sorting processing technology
Field.
Background technique
In China's gold geology reserves, Indigenous Gold-bearing accounts for the 42.23% of gross reserves, for the overwhelming majority.With lode gold ore
A large amount of development and utilization of resource, easily select easy to handle gold mine fewer and fewer, and the refractory gold ore that disseminated grain size is thin, grade is low then increasingly increases
It is more.And flotation-carbon-in-pulp process is common process for extracting gold in China.Flotation-carbon-in-pulp process floatation process obtains
The general gold grade of concentrate should reach 50g/t or more, generated in the grinding process of flotation-carbon-in-pulp process floatation process
A large amount of subparticles (secondary slimes), the adverse effect of more pairs of flotation of secondary slime is bigger, current coarse sand and secondary ore
It is ineffective that mud does not separate floatation process, therefore, secondary slime of how going out in grinding process, to yellow Au plasma have to
Close one of the project of important meaning and those skilled in the art's research.
Summary of the invention
The present invention provides a kind of lode gold ore to solve the problems, such as a large amount of secondary slime that gold ore generates in ore grinding
Secondary slime and rough just separating flotation technique.
The technical scheme to solve the above technical problems is that a kind of secondary slime of lode gold ore and it is rough just point
It from floatation process, is characterized in that, including jaw crusher, level-one ball mill, second level ball mill, Taylor standard sieve, rotation
Wind separator, three-level ball mill and flotation cell, above level-one ball mill to the conveyer belt for transporting ore between second level ball mill
Level-one electromagnet is installed, is transported between second level ball mill and Taylor standard sieve and two-stage electromagnetic is installed above the conveyer belt of ore
Iron；Ore is transported to level-one ball mill after jaw crushing crusher machine and carries out first ball milling, the primary generated after first ball milling
Mineral aggregate is transported to second level ball mill by conveyer belt, and primary mineral aggregate passes through level-one electromagnet, level-one electromagnet during transport
Ferrous contaminants in the primary mineral aggregate in removal part, primary mineral aggregate form secondary mineral aggregate, secondary mine in second level ball mill after ball milling
Material passes through two-stage electromagnetic iron on the conveyer belt for send to Taylor standard sieve, and two-stage electromagnetic iron further removes in second level mineral aggregate
Ferrous contaminants；Taylor standard sieve sieves mineral aggregate, and screening out the part come is three-level mineral aggregate, and sieve stays part to be again fed to second level
Ball mill continues ball milling；Three-level mineral aggregate is transported to cyclone separator, cyclone separator by three-level mineral aggregate be separated into secondary slime and
Material containing gold mine, material containing gold mine are sent into flotation cell and carry out flotation.
Further, the Taylor standard sieve uses the Taylor standard sieve of 100 mesh.
Further, the separation custom of the cyclone separator is
The application's is a little: using the combination of ball mill, Taylor standard sieve and cyclone separator, passing through fine ore grinding
It is more broken by the thinner of the middle hardness ore mill below in ore, and gone during transhipment by the way that electromagnet is preliminary
Except iron tramp therein, sufficiently fine ore is ground into after Taylor standard sieve sieves, and the thin mineral aggregate separated is sent
Enter cyclone separator separation, after attempting and testing for a long time, selectsWind speed,
Under this wind speed, isolated effect is best, can secondary slime at separation as much as possible in mineral aggregate, realize the application separation
Purpose, provide more suitable condition further to separate and extracting gold from floatation process, reduce making for chemical raw material
With, influence of the reduction to environment, and improve the extraction efficiency of gold.
