Abstract
The invention discloses a method for recovering wulfenite through combining falcon centrifugal reselection with flotation. A raw ore is grinded to a fineness of -0.074 mm by 70-80%, so that the wulfenite is dissociated from a gangue mineral; a falcon centrifugal ore separator is used for separating to obtain a wulfenite gravity concentrate; after a falcon centrifugal gravity tailing is concentrated, a sulfuric acid cleaning ore and a sodium sulfide activated wulfenite are added in sequence by each ton of centrifugal tailing; then, a collecting agent and a foaming agent 730A are added to perform the flotation of the wulfenite; and foams are scraped out to obtain a wulfenite flotation concentrate. The method is universally suitable for separation of the wulfenite and the gangue mineral; the falcon centrifugal ore separator can more effectively recover the wulfenite with a particle size not smaller than 10 microns; and the wulfenite with a particle size smaller than 10 microns can be recovered through flotation, so that the wulfenite recovery rate is greatly increased.
Description
Technical field
The invention belongs to sorting mineral technical field, be specifically related to the method that technique that a kind of falcon of employing centrifugal reselection combines with flotation reclaims wulfenite.
Background technology
Molybdenum is a kind of important rare metal, tool has been widely used: along with China's expanding economy, the demand of the basic materials such as iron and steel is got more and more, is widely used in and produces various steel alloy, cast steel, tool steel and stainless steel etc., to strengthen the intensity of steel, toughness and corrosion resistance; Molybdenum oxide and molybdate be chemistry and petroleum industry in excellent catalyst; Along with the application of molybdenum at other alloy field and chemical field also constantly expands, also increasing to the demand of molybdenum, therefore improve the dressing level of Molybdenum Mine, improve the comprehensive utilization ratio of Mo resource, high-quality molybdenum product is provided more, keeps sustain economic stable development significant to China.Present molybdenum mainly extracts from sulphide ore, but oxidizing molybdenum ore is also the important sources of molybdenum, and wulfenite is also known as wulfenite, yellow lead ore, it is the important source of extracting molybdenum, because it is than great, native floatability is poor, and conventional gravity treatment or sulfide flotation sort.But though traditional gravitational separation equipment can effectively reclaim larger particles ore as spiral chute, shaking table etc., be difficult to reclaim the smitham in ore, cause recovery rate in ore-dressing low; Traditional sulfide flotation method, also can only sort the good wulfenite of floatability.Therefore in order to improve the dressing level of wulfenite, the exploitation of such ore are accelerated, just the ore-dressing technique of a kind of more efficient wulfenite of necessary research and development.
Summary of the invention
Of the present inventionly be the method that the technique providing a kind of falcon of employing centrifugal reselection to combine with flotation reclaims wulfenite.
Object of the present invention is realized by following proposal:
1. raw ore is milled to the fineness that-0.074mm accounts for 70% ~ 80%, and wulfenite and gangue mineral are dissociated;
2. adopt falcon centrifugal ore separator to be 2600 ~ 3200ml/min at back-flushing flow, to carry out sorting under the condition of centrifugal force 220 ~ 300g, obtain wulfenite gravity concentrate;
3. falcon centrifugal reselection Tailing thickening is dewatered to the concentration of mass percent 30% ~ 35%;
4. in centrifugal mine tailing per ton, add 260 ~ 500g sulfuric acid cleaned mineral surfaces, 2 ~ 4min, 1500 ~ 3000g vulcanized sodium activation wulfenite, 3 ~ 6min, then add collecting agent isoamyl xanthate 100 ~ 250g and foaming agent 730A40 ~ 50g effect 1 ~ 2min and carry out flotation wulfenite, scrape foam and namely obtain wulfenite flotation concentrate.
Advantage of the present invention and technique effect:
Adopt centrifugal ore separator falcon more effectively can reclaim the wulfenite of Li Du≤10 micron, and flotation can the wulfenite of recovery size ﹤ 10 microns, the combination both them can improve the rate of recovery of wulfenite greatly.
