Abstract
The invention discloses an oredressing method for tantalum-niobium ore, which belongs to the technical field of mining industry. The method is implemented through the following steps: performing magnetic separation at three levels on mineral powder and then performing wet-material magnetic separation, wherein the magnetic field intensity for magnetic separation is more than 2,000 GS, and the rotating speed of a magnetic roller is 200 to 420 r/min; concentrating and desliming tailings after magnetic separation through a spiral classifier; returning sand into a ball mill for fine grinding; allowing the ball mill to discharge ore into a spiral chute for roughing; and performing shaking-table selection on spiral-chute concentrate so as to obtain final tantalum-niobium concentrate. The combined process method has the advantages of ensuring that the ore utilization rate can reach 80 percent, using little water during a process, saving water, reducing cost and pollution and causing no air pollution as dust in magnetic separation is gathered by a dedusting device.
Description
Technical field: the invention belongs to the mining industry technical field, be specifically related to a kind of production method of tantalum niobium concentrate ore dressing.
Background technology: mineral metal products is that national economy, national daily life and national defense industry, sophisticated technology and high-tech industry must indispensable basic material and important strategic goods and materials.The output of iron and steel and non-ferrous metal often is considered to the embodiment of a national national power.The maximum characteristics in ore deposit are that oil in place is big, and it is low to contain the tantalum grade, and the useful component of association is many, the comprehensive utilization value height.The recovery method that adopt in existing ore deposit is the high frequency fine screen Process by grading, and this method partition size can only be 0.5mm, causes the raw ore feed preparation unit size thick partially.Not only had a strong impact on and selected sorting of grade well, and the easy mill that makes a part should enter mill density current journey selects the tantalum niobium concentrate logistics people who does not but dissociate to mine tailing well, make tailings grade higher, cause a large amount of metal losses.
Summary of the invention: the present invention passes through research repeatedly, and the existing method of tantalum niobium concentrate ore dressing is improved, and has optimized the condition of ore dressing, so that select, realizes the maximum utilization of resource.
The present invention is achieved in that it mainly is earlier breeze to be carried out three grades of magnetic separation to handle, again through the wet feed magnetic separation, the selected magnetic field intensity of magnetic separation is greater than 2000GS, the magnetic drum rotating speed is 200～420 rev/mins, wet feed makes the finished product fine ore through dehydration, general tantalum content of niobium is at 10% ore, the tantalum-niobium concentrate powder content can reach 50% after this method magnetic separation, this combined technique, and the ore utilization rate can reach 80%, water consumption is few in the technical process, save water, reduce cost, reduce and pollute, dust in the magnetic separation is captured by dust arrester, can not cause air pollution, the mine tailing after the magnetic separation concentrates desliming, the fine grinding of sand return goal ball mill through spiral classifier, the ball milling ore discharge advances spiral chute to be roughly selected, and spiral shell slide concentrate sorts through shaking table and obtains final tantalum-niobium concentrate.Spiral shell slide mine tailing and shaking table mine tailing enter the feldspar recovery system and reclaim feldspar, and the spiral classifier overflow is advanced to spread the cloth chute and reclaimed the fine fraction tantalum-niobium concentrate.
This method technology is simple, the mineral amount height of choosing, and tantalum niobium yield height is easy for advantages such as suitability for industrialized production, is particularly suitable for the mining area and uses.
The specific embodiment: the present invention is described in detail below in conjunction with embodiment.
Embodiment 1
The ore that contains tantalum niobium concentrate is pulverized earlier, then breeze being carried out three grades of magnetic separation handles, again through the wet feed magnetic separation, the selected magnetic field intensity of magnetic separation is 3000GS, the magnetic drum rotating speed is 3000 rev/mins, wet feed makes the finished product fine ore through dehydration, one tantalum content of niobium is 12%, the tantalum-niobium concentrate powder content is 47.2% after this method magnetic separation, mine tailing after the magnetic separation concentrates desliming through spiral classifier, the fine grinding of sand return goal ball mill, the ball milling ore discharge advances spiral chute to be roughly selected, and spiral shell slide concentrate sorts through shaking table and obtains final tantalum-niobium concentrate.
