Technical field
The invention belongs to mineral floating technical field, relate to a kind of experimental provision, particularly relate to a kind of countercurrent flotation experimental provision.
Background technology
Along with the large-scale development of mineral resources, milling ore granularity is more and more thinner.Fine mineral makes sorting difficulty strengthen due to features such as quality are little, collision probability is low, can not effectively be reclaimed.To this, dresser author has carried out a series of research from aspects such as medicament, floatation equipment and techniques.Wherein, countercurrent flotation column is widely applied for the separating effect that fine mineral is good with it.The determination of industry flotation column performance parameter needs first to carry out conditional FP tree test in laboratory, and flotation column test in laboratory adopts the method for continuous flotation, the required a large amount of sample ore of the method, and the test period is longer, and the labour intensity of experiment work person is large; The material of each moment sorting in floatation process and the froth pulp character obtained basically identical, mineral floatability rule over time be investigated, floatation equipment need be added again and sample separately, virtually turn increase manpower and materials.
Therefore, develop a kind of consume sample ore is few, easy and simple to handle, operating cost is low laboratory floatation equipment for the shortening test period, reduce workload, energy-saving and cost-reducing etc. seem particularly important.
Summary of the invention
Object of the present invention provides for weak point existing in above-mentioned prior art the countercurrent flotation experimental provision that a kind of structure is simple, automaticity is high, easy and simple to handle, operating cost is low just.
Object of the present invention realizes by following technique measures:
Device of the present invention take countercurrent flotation column as core component, is separately equipped with agitator, air compressor, feed pump, middling cycle pump, foam jet water pump, Liquid level pump, fluid flowmeter, gas flowmeter, described agitator is connected with countercurrent flotation column middle and upper part by feed pump and corresponding pipeline, the mine mouth being arranged in countercurrent flotation column bottom is connected with the middle and upper part of countercurrent flotation column by middling cycle pump and respective line, countercurrent flotation column cylinder bottom is provided with the micropore ceramics for generation of bubble, micropore ceramics is connected with air compressor by pipeline, Liquid level pump is connected with countercurrent flotation column middle and upper part by pipeline and control valve, foam bath is squeezed in the foam tank of countercurrent flotation column by foam jet water pump by pipeline and control valve, described Liquid level pump, foam jet water pump is connected with water tank respectively by pipeline.(be saving equipment, Liquid level pump and foam jet water pump share a water tank).
The discharge gate place of agitator of the present invention is provided with the valve for preventing flotation column feeding pipe from blocking; The gas flowmeter for controlling aeration quantity size is provided with on described micropore ceramics to be connected pipeline with air compressor; Middling cycle pumps the fluid flowmeter expecting pipeline to be provided with for measuring middling cycle amount; Middling cycle pumps into the blow-off valve expecting pipeline to be provided with for collecting mine tailing.
The reading of fluid flowmeter described in the present invention can show by real-time online; Flotation column liquid level adds water and flush with foam water is added automatically by Liquid level pump and foam jet water pump respectively.
Operation principle of the present invention is as follows:
When the ore pulp in agitator feeds 2/3rds of flotation column height, middling cycle pump is started working, and after ore pulp all feeds, closes feed pump; After middling cycle pump work certain hour, open air compressor, and simultaneously adjusting gas flow meter; In time having froth pulp to discharge, open Liquid level pump and foam jet water pump; Start timing sampling (start emersion with foam and be designated as 0 min), get the froth pulp in different time sections respectively; After flotation terminates, close air compressor, Liquid level pump, foam jet water pump and middling cycle pump, open blow-off valve, collect flotation tailing; After flotation tailing is drained, ore pulp remaining in flotation column is rinsed well by unlatching Liquid level pump and middling cycle pump, collects in mine tailing bucket in the lump; Finally the product collected is dried and weigh and survey grade.In process of the test, for keeping certain froth bed thickness, cylinder domestic demand adds a certain amount of water, and addition is determined according to the stratification interface height of froth bed and ore pulp.
Flotation column feed described in the present invention, the water yield are added and flush with foam all achieves automatic ration interpolation; Middling cycle amount and aeration quantity can be surveyed adjustable.
Beneficial effect of the present invention is as follows:
Owing to have employed such scheme, after adopting micropore ceramics and gas flowmeter to combine, the controlled microvesicle of size can be produced in flotation column, be beneficial to mineral floating; Flotation column feed, the water yield are added and flush with foam automatic ration adds, and middling cycle amount and aeration quantity can be surveyed adjustable, achieve the accurate control of floatation process, and the workload of testing crew also reduces greatly simultaneously; Test adopts batch flotation test method, and compared with the continuous flotation pattern of Routine Test Lab flotation column, required sample ore reduces, and the floatability of floatation process Minerals is deteriorated gradually with flotation time, is convenient to the analysis of mineral floatability; Flotation column height reduction, saves processing cost.Application countercurrent flotation experimental provision and method, efficiently solve needed for flotation column laboratory test the bottleneck that sample ore is many, the test period is long, workload is large, have the advantages that system architecture is simple, good reliability, automaticity are high, easy and simple to handle, operating cost is low, the laboratory test of flotation column can be widely used in, also can be used for classroom instruction.
Compared with the continuous flotation pattern of traditional experiment room flotation column, needed for this experimental system, sample is less, is convenient to carry out the test of mineral conditional FP tree; Flotation time shortens, and operating efficiency improves; The floatability of floatation process Minerals is deteriorated gradually with flotation time, is easier to the analysis of mineral floatability; System architecture is simple, automaticity is high, easy and simple to handle, test accuracy is high, operating cost is low, and the laboratory sorting for flotation column provides a new method; Exploitation for the analysis of mineral floatability and flotation flowsheet has important value and significance.
