Tantalum and niobium ore dressing (processing of tantalum and niobium ores) from ore containing tantalum and niobium tantalum and niobium mineral separation and concentration process. The mineral processing product is antimony concentrate. Minerals and Resources There are about 130 minerals in the natural world, of which about 80 are minerals. Important industrially valuable niobium minerals are listed in the table. Further, part of niobium tantalum titanium present in iron ore, perovskite, rutile, cassiterite, wolframite and sphene as impurities. The antimony deposit is divided into five types: magmatic deposit, pegmatite deposit, gas-forming hydrothermal deposit, contact metamorphic deposit and exogenous deposit. The type of strontium ore can be divided into three major categories: coltan-iron-iron ore, chlorite ore and other strontium-bearing ore. Antimony deposits are widely distributed in Brazil, the former Soviet Union, China, Canada, the United States, Nigeria, Australia, Zaire, Kenya, Tanzania, Uganda, Malaysia, and Thailand. The main producers of antimony and antimony concentrates are Canada, Brazil, Australia, Zaire, the former Soviet Union, and Thailand. The United States and Japan are major consumers. Process flow The mineral composition of strontium ore is complex, the composition is unstable, and the content of valuable components is low, so the process of mineral processing is complicated. Generally, the beneficiation process of Yankuang consists of two parts: rough selection and selection. Different ore types of ore contain different types of antimony minerals, so the ore processing process is also different. Primary coltan and fine spar beneficiation process Such tantalite ores, columbite multiple symbiotic beryl, spodumene, cassiterite. The rough selection mainly adopts the multi-stage re-election process of multi-stage grinding. For some rough ore selection, re-election, flotation, re-election or re-selection is also used. The selection process uses a combined process. According to the minerals and associated minerals, the combined process of magnetic separation, re-election, flotation, flotation, re-election, electro-election, and chemical beneficiation is often used. If there is much mud in the ore, it should be delimed in advance. The strontium-rich fine spar is finely divided by the flotation process because of its fine grain size (see mineral grain size). Beneficiation process of strontium iron ore-iron ore mine The minerals in this type of ore have been largely dissociated, with a useful mineral density greater than 4 and some minerals being magnetic. The re-election process is used for rough selection. The selection of the obtained coarse concentrate mainly adopts a magnetic separation-reselection, a magnetic separation-electrification and a flotation combined process. Chlorite processing process Chlorophyll has two main types of carbonate rock and pegmatite. The carbonate rock glauconite deposit is large in size and high in strontium content, which is an important type of deposit. Due to the different mineral types and contents in the ore, two processes of re-election, magnetic separation-flotation and roasting magnetic separation are adopted. The coarse selection of pegmatite wurtz adopts multi-stage crushing and grading re-election process. The selected process uses magnetic separation to exclude tailings and flotation to obtain pyrite concentrate. Zircon in the coarse concentrate is sometimes removed by electrowinning or flotation. The typical ore dressing plant Yichun Yankuang Concentrator is located in Yichun City, Jiangxi Province, China. The ore used is a granite polymetallic deposit; the ore contains (Ta, Nb) 2O 50.03% (Ta: Nb = 1.8: 1). The size of the ore dressing plant is 1500t/d; the process of mineral processing is washing, crushing, screening, grinding, grading, magnetic separation and re-election combined process and re-election process; after the ore rod is ground to -0.5mm, magnetic separation and re-election are combined. In the process, part of the antimony concentrate is obtained; the tailings are re-ground to -0.2mm and the re-election process is used to obtain fine-grained antimony concentrate. The antimony concentrate contains (Ta, Nb) 2O 544.91%, and the recovery rate is 45.6%. Limu tin ore dressing plant Located in the Guangxi Zhuang Autonomous Region of China. The production scale is 1000t/d. The ore used is a tin-niobium-tungsten polymetallic granite deposit. The ore contains (Ta, Nb) 2O5, 0.0229%. The beneficiation process includes multi-stage crushing, pre-screening, centralized treatment of the slime, and re-election to obtain the mixed coarse concentrate. Then use the re-election of a strong magnetic separation combined process flow selection. The antimony concentrate contains (Ta, Nb) 2O52.515%, and the recovery rate is 40%. The magnetic separation tailings are then smelted by fire. Taimei Mine Ore Dressing Plant Located in the Guangdong Province of China, the ore used is a granite weathered crust-manganese deposit. The ore contains (Ta, Nb) 2O50.029%. The rough selection uses a re-election-magnetic separation re-synthesis process. The selection uses a re-selection magnetic separation-electrical selection-flotation combined process. The bismuth iron ore contains Nb2O560%, and the recovery rate is 42.51%. Niobec's Chlorochlor concentrator is located in Quebec, Canada. The ore used is a carbonated strontium deposit. The production scale is 2085t/d. The ore contains Nb2O50.58%~0.66%. The two-stage grinding flotation-magnetic separation combined process includes grinding, de-sludge, carbonate mineral flotation, de-sludge, magnetic separation, chlorite flotation, and pyrite flotation. Pyrochlore concentrate leaching dephosphorization, floating sulfur leaching residue. The final concentrate of the yellow earth stone contains Nb2O 560% to 62%.
