Ore beneficiation skills tantalum, niobium, tantalum and niobium ore beneficiation as usual to accept re-election to abandon most of the gangue minerals, get confuse low-grade crude ore into the selection of the job crude concentrate mineral composed of a large, generally contains a variety of useful minerals Sorting is difficult, and it usually accepts a variety of mineral processing methods such as re-election, flotation, electromagnetic selection or selection of metallurgical solidarity processes to select and disseminate a variety of useful minerals.
The foreign ore dressing treatment will punish the ore with a large content of fine ore or raw mud, and the washing operation will not be less. Australia Grinbus mine weathered pegmatite alluvial clay rough selection plant, set up two washing system, the original mine with a diameter of 1.5m, a pore size of 10mm cylindrical sieve twice after washing, under the sieve selected, sieve large and The clay ball is ground into a self-grinding mill for about 4 mm, and then sieved with a cylindrical sieve having a hole diameter of 10 mm. The material under the sieve is selected, and the material on the sieve is discarded or returned to be ground. The water consumption for washing is 5m3/t, and the cylinder screen treatment is 350 tons/hour.
The foreign glutinous concentrator cherishes the high-efficiency grinding grading configuration to low muddy mineralization. The Green Plains mine's primary pegmatite roughing plant achieved good results with the surrounding concentrating rod mill and vibrating screen closed circuit. The Burning Lake mine in Canada has been continuously innovated, and the contemporary acceptance of the grinding process is very distinctive. The mine is closed with a 2.4m×3.6m Marcy-type lattice ball mill AC horizontal vibrating screen (straight screen), the sieve size is 2.5mm, and the sieve is graded by 0.2mm with Derrick sieve, -2.5+0.2mm The grade is sorted by a spiral concentrator, and the tailings are dehydrated by a curved sieve and returned to re-grind. The ball mill has two kinds of commodities to form a cycle, that is, to accept a two-stage closed-circuit grinding. After the grinding circuit is adjusted, the cyclic load rate is usually 180% up and down, and the cyclic load is small and easy to form excessive damage.
Abroad roughing tantalum niobium iron ores is still reselection based, multi-use and efficient reselection configuration, the flow schematic. For example, the Grimbs mine directly uses a jig for rough selection of -10mm ore. The re-election-flotation-re-election process formed in the 1980s in Bonn Lake, Canada, is becoming more and more perfect. The process is still dominated by re-election, and flotation is only used to deal with fine mud. The re-election configuration uses a GEC spiral concentrator, a 3-layer suspended Dyest shaker, a Holman slime shaker, and a cross-flow belt concentrator. The former Soviet Union accepted the flotation to evacuate the coltan, fine-grain and topaz in the re-selected concentrate. The collector was hydroxamic acid, the mediator was oxalic acid, and floated in hydrochloric acid medium (pH 2). When Ta2O5 is contained at 2.52%, the concentrate grade is 27%, and the adoption rate is 90%.
Machining Steel is the use of CNC machining out,and the machining services including drilling, boring, cutting,meatl bending/metal bending, machining Steel Product material: carbon steel, 20#, 45#, A3, Q235,35Cr2MnMo and other series. In the high-speed machining out of the workpiece has a good finish. But machining Steel of the workpiece is easy to rust, so it will do heat treatment, surface nickel plating, chromium plating, surface black heat treatment, etc.. We have a special inspection department to carry out inspection, ensure the material aging hardness and each size to meet the requirements of the drawings, including the Machining Steel Parts application in various industries: automotive, marine, communications, medical equipment, industrial automation equipment.Except them,we supply the sheet metal operations.
