What Are Tungsten Tailings?<\/h2>\n

Rejeitados de tungst\u00e9nio<\/strong> are residual materials generated after extracting tungsten from ore slurry. Composed primarily of gangue minerals and surrounding rock, they contain fluorite, quartz, garnet, feldspar, mica, and calcite,<\/em> along with trace amounts of valuable metals such as molybdenum, niobium, tin, copper, lead, zinc, and even precious metals like gold and silver.<\/em><\/p>\n

Proper utilization of tungsten tailings not only enhances tungsten product quality but also maximizes mineral resource efficiency, reducing environmental waste.<\/p>\n

How to Effectively Use Tungsten Tailings?<\/h2>\n

Recuperar metais \u00fateis em rejeitos de tungst\u00e9nio, tais como estanho, molibd\u00e9nio, ni\u00f3bio, cobre, chumbo, zinco, antim\u00f3nio, bismuto, cobalto, ouro, prata, etc. Pode n\u00e3o s\u00f3 melhorar a qualidade dos produtos de tungst\u00e9nio, mas tamb\u00e9m fazer uma utiliza\u00e7\u00e3o eficaz dos recursos minerais.
\nThe valuable metals currently recovered are mainly tungsten, molybdenum, and rhenium.<\/p>\n

Recovering Valuable Metals from Tungsten Tailings<\/h2>\n

Tungst\u00e9nio<\/h3>\n

A limpeza dos rejeitos de tungst\u00e9nio \u00e9 uma forma eficaz de melhorar a taxa de recupera\u00e7\u00e3o do min\u00e9rio de tungst\u00e9nio.<\/p>\n

The recovery of tungsten from tungsten tailings and fine tungsten mud is achieved by a combined metallurgical process, and the recovery rate of WO3 is up to 82.6%.<\/p>\n

O flotation method for tungsten ore<\/strong> is extended to tungsten tailings and fine mud, and 18% tungsten crude concentrate of WO3 grade is obtained. The crude concentrate is directly alkali-decomposed, and the leaching efficiency is remarkably improved.<\/p>\n

O micro-bubble technology<\/strong> was used to recover fine-grained scheelite from scheelite flotation tailings, and the recovery rate in the range of 5~38\u03bcm was 65%.<\/p>\n

A separa\u00e7\u00e3o magn\u00e9tica de alto gradiente foi utilizada para recuperar a volframite dos rejeitos de flota\u00e7\u00e3o de scheelite. Ap\u00f3s uma sele\u00e7\u00e3o grosseira, uma limpeza e uma separa\u00e7\u00e3o magn\u00e9tica forte, verificou-se que o concentrado magn\u00e9tico forte de volframite de grau 0,43% f WO3 obtido a partir dos rejeitos 0,20% WO3, a taxa de recupera\u00e7\u00e3o de tungst\u00e9nio de 73,26%.<\/p>\n

Molybdenum, Bismuth Recovery<\/h3>\n

Muitos dep\u00f3sitos de tungst\u00e9nio est\u00e3o associados a v\u00e1rios graus de molibd\u00e9nio e bismuto, embora algum molibd\u00e9nio e bismuto possam ser recuperados durante as opera\u00e7\u00f5es de separa\u00e7\u00e3o por gravidade, devido \u00e0 capacidade natural de flutua\u00e7\u00e3o do molibd\u00e9nio e do bismuto, \u00e9 frequentemente flutuado para os rejeitos, resultando numa baixa taxa de recupera\u00e7\u00e3o de molibd\u00e9nio e bismuto.<\/p>\n

Rejeitados de tungst\u00e9nio por gravidade - flota\u00e7\u00e3o de molibd\u00e9nio e bismuto diretamente
\nRejeitados de lamas finas - primeiro a concentra\u00e7\u00e3o, depois a flota\u00e7\u00e3o<\/p>\n

Non-metallic Minerals Recovery<\/h3>\n

The non-metallic minerals in tungsten metal are mainly quartz, feldspar, mica, garnet, fluorite, and calcite; among them, fluorite and garnet have recovery value.<\/p>\n

1. Fluorite<\/h4>\n

Fluorite is an important non-metallic mineral widely used in chemical, metallurgical, and building materials industries. The grade of fluorite ore in China is generally low, and the associated deposits account for 43%. The recovery of fluorite minerals in tungsten tailings is of great significance.<\/p>\n

2. Garnet<\/h4>\n

Garnet is a weak magnetic mineral with high hardness and chemical stability. It is mainly used in abrasives, building materials, and polymer fillers. The garnet ore grade is not high, and the industrial-grade requirement is more than 14%. It is the basis of deep processing of garnet by magnetic separation and gravity to increase the garnet grade.<\/p>\n

 <\/p>\n

Tungsten Tailings For Building Materials<\/h2>\n

Os principais componentes dos rejeitos de tungst\u00e9nio s\u00e3o \u00f3xidos de sil\u00edcio e alum\u00ednio, que s\u00e3o semelhantes aos materiais de constru\u00e7\u00e3o tradicionais. Al\u00e9m disso, os rejeitos de tungst\u00e9nio s\u00e3o mais finos e n\u00e3o precisam de ser triturados, o que tem as vantagens de baixo consumo de energia e baixo custo.<\/p>\n

1. Tungsten Tailings for The Cement Industry<\/h3>\n

The use of tungsten tailings as a raw material for the production of cement can reduce the amount of fluorite. When the mass fraction of WO3 in raw meal is 1×10~6×10, it can improve the burnability of raw materials and is beneficial to the formation of cement clinker mineral Elite. The escape rate of tungsten is almost zero, and it can reduce the escape of lead, mercury, and fluorine, and can be used as an environmentally friendly cement clinker mineralizer.<\/p>\n

A utiliza\u00e7\u00e3o de rejeitos de tungst\u00e9nio como mat\u00e9ria-prima para o cl\u00ednquer de cimento reduz a polui\u00e7\u00e3o de fl\u00faor e enxofre.<\/p>\n

No entanto, os rejeitos de tungst\u00e9nio s\u00e3o utilizados como mat\u00e9rias-primas para a produ\u00e7\u00e3o de cimento para controlar a quantidade de adi\u00e7\u00e3o, e quantidades excessivas podem causar efeitos secund\u00e1rios.<\/p>\n

2. Tungsten Tailings for Glass-ceramics<\/h3>\n

A vitrocer\u00e2mica \u00e9 um novo material de constru\u00e7\u00e3o com elevado brilho e resist\u00eancia. J\u00e1 no in\u00edcio da d\u00e9cada de 1960, a antiga Uni\u00e3o Sovi\u00e9tica levou a cabo investiga\u00e7\u00e3o e produ\u00e7\u00e3o de vitrocer\u00e2mica para a prepara\u00e7\u00e3o de rejeitos, tendo-se posteriormente desenvolvido em muitos pa\u00edses e formado uma produ\u00e7\u00e3o em grande escala.<\/p>\n

Tungsten glass-ceramics prepared by the cast-forming method using tungsten tailings as the main raw material without adding a crystal nucleating agent, simple and low cost, the main crystal phase of which is \u03b2-wollastonite, and its nucleation and crystallization mechanism belongs to surface nucleation and crystallization.<\/p>\n

3. Other Applications of Tungsten Tailings<\/h3>\n

Para al\u00e9m das aplica\u00e7\u00f5es acima referidas, os rejeitos de tungst\u00e9nio s\u00e3o tamb\u00e9m utilizados noutras aplica\u00e7\u00f5es, tais como biocer\u00e2mica, materiais polim\u00e9ricos minerais, azulejos de cer\u00e2mica e similares.<\/p>\n

The tungsten tailings are used as raw materials, and the slag, fly ash, and clay are used as auxiliary materials. The porous bioceramic filter material can be produced by roasting.<\/p>\n

Os rejeitos de tungst\u00e9nio e o metacaulino s\u00e3o as principais mat\u00e9rias-primas, e o vidro de \u00e1gua e o NaOH s\u00e3o activadores alcalinos para produzir materiais polim\u00e9ricos minerais.<\/p>\n

Tamb\u00e9m \u00e9 poss\u00edvel utilizar os rejeitos de flota\u00e7\u00e3o de tungst\u00e9nio como mat\u00e9ria-prima para produzir azulejos de cer\u00e2mica, o que pode reduzir eficazmente a temperatura de cozedura e reduzir o custo de produ\u00e7\u00e3o.<\/p>\n

At present, the domestic reserves of tungsten resources are declining year by year, the grade of raw ore is getting lower and lower, and tungsten tailings resources are being recovered for valuable metals and non-metallic minerals, which can effectively improve resource utilization.<\/p>\n

 <\/p>\n

Conclusion: Maximizing Resource Efficiency<\/h2>\n

As tungsten ore grades decline, tailings recycling<\/strong> is essential for sustainable resource management. Whether recovering valuable metals or converting waste into construction materials, effective processing ensures economic and environmental benefits.<\/p>\n
