Specific embodiment
The present invention is illustrated below in conjunction with accompanying drawing
A kind of molybdenum floatation process, it is characterized in that through roughing and repeatedly scan after obtain rough concentrate, rough concentrate is by 10 levels
It is selected, molybdenum by being enriched with step by step, foam containing molybdenum enter next stage flotation device, mine tailing return upper level flotation device, at the 7th grade or
Add the vulcanized sodium of solid, vulcanization na concn to reach saturation during the 8th grade or the 9th grade selected, selected foam is carried out at the 10th grade
Collect, 2~3 foams are collected in 24 hours, the foam of collection obtains product through dewater treatment, and the selected stage is flow automatically using foam
Formula multistage flotation device carries out selected step by step, and foam gravity flow multistage flotation device is by multiple self-suction type flotation machines successively cloth
Put, each flotation device includes cabinet 1, the air intake duct 2 in cabinet 1, be followed successively by first order machine to the tenth grade of machine, two flotation devices it
Between set from circulation road, from the foam layer height that the two-port of circulation road is opened on the wall of cabinet 1, gravity flow channel bottom by prime
Machine is inclined to rear class machine, and wherein prime machine is that high-end, rear class machine is low side.The impurity such as copper, iron are pressed onto bottom by vulcanized sodium, and molybdenum is stained with
Floated to bubble, the foam of prime machine is drawn onto rear class machine by the negative pressure that rear class machine is produced by from circulation road, and rear class machine is again
Secondary flotation, the so many flotation of machine one-level one-level finally obtain satisfactory band ore deposit foam, and saving will be again after scraper plate is scraped off
Transhipment step needed for secondary flotation, time saving, laborsaving, efficiency high.
It is gravity flow cell body 3 from a kind of structural formula of circulation road, open topped, two-port is the breach on the wall of cabinet 1.Gravity flow
The runner of cell body 3 sets gate 4, and gate 4 inserts gate slot 5, and the edge of gate 4 sets rubber layer, can carry out separate unit flotation with closed shutter 4
Operation, rubber layer makes gate 4 tightr in the contact of gate slot 5.The top of gate 4 is provided with handle 7, can conveniently lift and put down.
The effect that foam is preferably inhaled to obtain is the gravity line 8 that can also be closing from circulation road, and gravity line 8 is pipe
Or other shapes.Gravity line 8 is provided with valve 9, same to close valve 9, carries out separate unit flotation operation.The one end of gravity line 8 is provided with expansion
Big mouth 10, makes the entrance subordinate flotation device that foam is as more as possible, fast.
In order to improve the potential energy for flowing to subordinate's flotation device of foam, rear class machine foam layer height is less than prime machine foam floor height
Degree, such foam quickly just exit into subordinate.
