Abstract
The invention relates a selecting finished ore filtration unit and method used for bauxite. The unit comprises stuff pump 1, concentration ore pulp delivery pipe 2 and ceramic filter 3 which is connected with 2. It is original to adopt the ceramic filter. Select the proper ceramic aperture according to particle size distribution to carry out filter. The concentration of ingress ore is 65%, at -200mesh and 75%, filter cake water content is 12% and filter liquor solid content is below 1g/t.
Description
Affiliated technical field
The present invention relates to a kind of concentrate selection filter and filter method, particularly relate to a kind of concentrate selection filter and filter method of suitable bauxite.
Background technology
At present, low-grade ore concentration of bauxite has been realized industrialization in.Ore concentration of bauxite is a new technology, and many operations all are first Application, therefore, adopts the equipment and technology that is fit to ore concentration of bauxite, is the necessary condition that guarantees that ore concentration of bauxite carries out smoothly.
The concentrate filtration operation of bauxite concentrate selection is the important step of contact ore-dressing practice and alumina producing operation, and the moisture content of concentrate filter cake and output directly have influence on the production of aluminium oxide.Therefore, select the filter plant of suitable concentrate selection extremely important.There was not filter at bauxite concentrate selection in the past, the concentrate selection that contrasts other metallic ores filters, adopt rotary drum filter, pressing filter, band filter, plate and frame filter press etc. to do the filtration test of bauxite concentrate selection, effect is all undesirable, main cause is that the filter cloth quality does not pass a test, filter the filtrate muddiness, filter cake moisture content is too high and energy consumption is too high, can not satisfy the requirement of industrial production to concentrate moisture and backwater quality.
Summary of the invention
The purpose of this invention is to provide the device that a kind of suitable bauxite concentrate selection filters, to satisfy the needs that ore concentration of bauxite is produced.
The present invention is achieved in that the bauxite concentrate selection filter to achieve these goals, and it comprises slag stock pump, transfer pipeline and filter, and wherein filter is a ceramic filter.
The bauxite concentrate selection filter method, it comprises following processing step: concentrate ore pulp and be transported to ceramic filter by the slag stock pump by transfer pipeline, be delivered to subsequent processing through conveying device again through the filter cake of ceramic filter filtering means dehydration.
Described conveying device is belt conveyor or screw pump.
The ceramic aperture of described ceramic filter is 2～4 μ m.
The application of ceramic filter in bauxite concentrate selection filters.
Advantage of the present invention and effect are as follows:
The Promethean ceramic filter that adopted in the bauxite concentrate selection filtering technique.According to the concentrate selection size distribution, select suitable ceramic aperture, carry out the filtration of bauxite concentrate selection.Adopt filter of the present invention and filter method, advancing under ore deposit concentration 65% ,-200 orders 75% situation, it is moisture 12% to get filter cake, and filtrate contains≤1g/t admittedly, satisfies fully and produces needs.
Description of drawings
Fig. 1 is a bauxite concentrate selection filter apparatus configuration schematic diagram of the present invention.
Among the figure, 1, the slag stock pump; 2, transfer pipeline; 3, ceramic filter; 4, conveying device.
The specific embodiment
Below embodiments of the invention are described in detail in conjunction with the accompanying drawings, but protection scope of the present invention is not limit by embodiment.
As shown in Figure 1, the bauxite concentrate selection filter is made of following structure: concentrate ore pulp and be made of slag stock pump 1, transfer pipeline 2 and the ceramic filter 3 that is connected with transfer pipeline 2, the filter cake that obtains after ceramic filter 3 filters is outwards carried through conveying device 4.The ceramic aperture of ceramic filter is 2～4 μ m.
Bauxite concentrate selection filter method: concentrate ore pulp and be transported in the half-moon groove of ceramic filter 3 through transfer pipeline 2 by slag stock pump 1, because vacuum action, solid mineral in the ore pulp is adsorbed on the ceramic wafer surface, after filtration, dehydration forms filter cake, by scraper filter cake is unloaded again, carry through conveying device 4.
Conveying device 4 be a belt conveyor when above-mentioned filter cake moisture content after being filtered by ceramic filter 3 was low, employing screw pump when the filter cake moisture content of output is high.
Claims (5)
1, bauxite concentrate selection filter, it comprises slag stock pump (1), transfer pipeline (2) and filter, it is characterized in that described filter is ceramic filter (3).
2, bauxite concentrate selection filter method according to claim 1, the ceramic aperture that it is characterized in that described ceramic filter (3) are 2～4 μ m.
3, bauxite concentrate selection filter method, it comprises following processing step: concentrate ore pulp and be transported to ceramic filter (3) by slag stock pump (1) by transfer pipeline (2), the filter cake after ceramic filter (3) filters is delivered to subsequent processing through conveying device (4) again.
4, bauxite concentrate selection filter method according to claim 3 is characterized in that described conveying device (4) is belt conveyor or screw pump.
5, the application of ceramic filter in bauxite concentrate selection filters.
