Description
Technical field
The present invention relates to mineral floating technical fields.
Background technique
Flotation technology is one of most common technology in mineral processing technology, using wide in global mineral processing technology
It is general.Flotation technology is the difference based on mineral grain Yu gangue particle surface nature, is carried out to gangue or mineral particle surface
After hydrophobic treatment, the particle of mineral or gangue is floated using the buoyancy of bubble, to realize gangue and minerals separation.It is floating
Select slot as the primary study object of the always global mineral processing technology personnel of equipment of floatation process.
Traditional flotation equipment generally divides three types,
The first is mechanical stirring inflation or induced air floatation slot, that is, traditional flotation cell, and such flotation cell is flotation equipment
Mainstream, the dressing plant in the whole world 90% still uses this traditional flotation cell, the reason is that this flotation cell belongs to the flotation being used in series
Slot, operation is easy to grasp after process settings, the numerous prices of equipment manufacturer also relative moderate.Although the equipment of this type has much
Patent, but the structure type of mainstream is still the technology using Beijing Mine and Metallurgy General Inst, and Beijing Mine and Metallurgy General Inst is about tradition
Patent CN87102140, CN87103290,93118179.8,94100667.0,94218361.4 of flotation cell substantially represent
The technical level of traditional flotation cell, such flotation cell need power device to drive rotor operating, the three-phase of ore pulp and bubble are mixed
Ore pulp sucking is closed, carries out shear-mixed with the bubble being filled with then to complete the mineralization process of mineral, the mine of this rotor structure
It is very low to starch kinetic energy conversion ratio, it is higher so as to cause equipment power consumption, and the bubble being filled with shears disperse by rotor, bubble is difficult to very well
Ground dispersion, wastes a large amount of compressed air, also brings the increase of energy consumption.
Second is air flotation column, and flotation column is that flotation function is become placement up and down by horizontal transition, is contracted significantly
Short beneficiation flowsheet, but since flotation column is to complete whole ore dressing process by a groove body, it may be only available for as coal slime is selected
Simple floatation process, be poorly suitable for the flotation of complicated metalliferous mineral, COLUMN TECHNOLOGY is mainly with China Mining University
97236893.0 Dual vortex static micro-foam flotation columns and Central South University 01145542.X are technology representative.
The third is short column microfoam flotation tank, and the technology prototype of such flotation cell teaches Zhan Mu derived from Australia in 1984
The flotation cell of the Venturi tube air-breathing mineralising of this invention, country estate coal washery 00207259.5,02234471.3 patent are the technology
Development is microvesicle fast-flotation technology, improves the service efficiency of such flotation cell, the micro- gas of Sun little Yu 201020167495.4
Steeping fast-flotation integrated mechanism, a kind of 201020108249.1 fast-flotation integrated systems technology development is integrated skill
Art, has widened the application field of the technology, 201020177313.1 high-efficiency self-circulation flotation cell of Ren Yi,
201020167521.3 tube bundle type microporous bubble mixer improves the efficiency of mineral mineralising comprehensively, so that short column microfoam flotation
Technology is improved day by day.
