Description
Technical field
The invention belongs to mining equiment flotation technology field more particularly to a kind of fluidization coarse flotation equipment and flotation sides
Method.
Background technique
In mineral manufacture field, flotation is the recycling most common method of valuable mineral.And flotation is for the grain of selected mineral
Spend it is more demanding, material size usually require that the specific gravity of 74 μm or less grades 60%~90% or so, the material size upper limit
Usually at 100~150 μm, and the particle relatively thick for 150 μm or more granularities, flotation recovery effect are poor, therefore thick
Particle usually requires to return to material size of the ball mill fine grinding to reach flotation.And for grade at 150 μm~1000 μm or so
Ore, regrind be easy to cause ore cross crush, lead to the unnecessary increase of thin mud amount, at the same increase again ore grinding at
This.The grade of valuable mineral is usually lower with respect to fine fraction ore in coarse granule ore, and grinding operation is all carried out to it and is caused
A degree of energy dissipation.Therefore, in the process flow of " ore grinding-flotation ", to grade on 150 μm~1000 μm left sides
Right ore carries out throwing tail in advance and has important practical significance.
Coarse granule is ineffective using traditional floatation equipment recycling.Coarse granule ore liberation degree of minerals is poor, ore
The exposure of surface valuable mineral is relatively low, poor with the function and effect of collecting agent, causes the hydrophobicity on ore particles surface inadequate,
It is smaller with the sticking probability of bubble；Coarse granule weight is relatively large, floats and needs the bubble of more volume and intensity, general gas
Bubble is formed by buoyancy and is not enough to bring coarse granule into froth bed；Coarse granule specific surface area is relatively small, the adhesion strength with bubble
It is relatively poor, adhesion time needed for cannot keep flotation and intensity, it is easy to fall off from bubble.Therefore, coarse granule mineral
Often sink to entering tailing in floatation process, causes the loss of valuable mineral.And for sorting coarse grained interference bed
Sorting machine, separating effect depend on the partial size and density of mineral, since the grade of valuable mineral in coarse granule is usually lower, divides
It is thin to dissipate disseminated grain size, causes the specific gravity of same particle size ore particles almost without difference, therefore hindered bed separator is to coarse granule
In valuable mineral recognition capability it is poor, equally will cause the loss of valuable mineral.Therefore, single traditional floatation equipment and again
Optional equipment all cannot achieve the high efficiente callback to coarse granule target minreal.
