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

R\u00e9sidus de tungst\u00e8ne<\/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

R\u00e9cup\u00e9rer les m\u00e9taux utiles dans les r\u00e9sidus de tungst\u00e8ne tels que l'\u00e9tain, le molybd\u00e8ne, le niobium, le cuivre, le plomb, le zinc, l'antimoine, le bismuth, le cobalt, l'or, l'argent, etc. Il permet non seulement d'am\u00e9liorer la qualit\u00e9 des produits de tungst\u00e8ne, mais aussi d'utiliser efficacement les ressources min\u00e9rales.
\nThe valuable metals currently recovered are mainly tungsten, molybdenum, and rhenium.<\/p>\n

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

Tungst\u00e8ne<\/h3>\n

La r\u00e9cup\u00e9ration des r\u00e9sidus de tungst\u00e8ne est un moyen efficace d'am\u00e9liorer le taux de r\u00e9cup\u00e9ration du minerai de tungst\u00e8ne.<\/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

Les 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

Les 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

La s\u00e9paration magn\u00e9tique \u00e0 haut gradient a \u00e9t\u00e9 utilis\u00e9e pour r\u00e9cup\u00e9rer la wolframite des r\u00e9sidus de flottation de la scheelite. Apr\u00e8s une s\u00e9lection grossi\u00e8re, un balayage et une s\u00e9paration magn\u00e9tique forte, on a constat\u00e9 que le concentr\u00e9 magn\u00e9tique fort de wolframite de 0,43% f WO3 obtenu \u00e0 partir des r\u00e9sidus de 0,20% WO3, le taux de r\u00e9cup\u00e9ration du tungst\u00e8ne est de 73,26%.<\/p>\n

Molybdenum, Bismuth Recovery<\/h3>\n

De nombreux gisements de tungst\u00e8ne sont associ\u00e9s \u00e0 des degr\u00e9s variables de molybd\u00e8ne et de bismuth. Bien qu'une partie du molybd\u00e8ne et du bismuth puisse \u00eatre r\u00e9cup\u00e9r\u00e9e au cours des op\u00e9rations de s\u00e9paration par gravit\u00e9, le molybd\u00e8ne et le bismuth sont souvent entra\u00een\u00e9s dans les r\u00e9sidus en raison de leur flottabilit\u00e9 naturelle, ce qui se traduit par un faible taux de r\u00e9cup\u00e9ration du molybd\u00e8ne et du bismuth.<\/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

Les principaux composants des r\u00e9sidus de tungst\u00e8ne sont des oxydes de silicium et d'aluminium, qui sont similaires aux mat\u00e9riaux de construction traditionnels. En outre, les r\u00e9sidus de tungst\u00e8ne sont plus fins et n'ont pas besoin d'\u00eatre broy\u00e9s, ce qui pr\u00e9sente l'avantage d'une faible consommation d'\u00e9nergie et d'un faible co\u00fbt.<\/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

L'utilisation des r\u00e9sidus de tungst\u00e8ne comme mati\u00e8re premi\u00e8re pour le clinker r\u00e9duit la pollution par le fluor et le soufre.<\/p>\n

Cependant, les r\u00e9sidus de tungst\u00e8ne sont utilis\u00e9s comme mati\u00e8res premi\u00e8res pour la production de ciment afin de contr\u00f4ler la quantit\u00e9 d'ajout, et des quantit\u00e9s excessives peuvent entra\u00eener des effets secondaires.<\/p>\n

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

La vitroc\u00e9ramique est un nouveau mat\u00e9riau de construction tr\u00e8s brillant et r\u00e9sistant. D\u00e8s le d\u00e9but des ann\u00e9es 1960, l'ex-Union sovi\u00e9tique a men\u00e9 des recherches et produit de la vitroc\u00e9ramique pour la pr\u00e9paration des r\u00e9sidus, qui s'est ensuite d\u00e9velopp\u00e9e dans de nombreux pays et a fait l'objet d'une production \u00e0 grande \u00e9chelle.<\/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

Outre les applications susmentionn\u00e9es, les r\u00e9sidus de tungst\u00e8ne sont \u00e9galement utilis\u00e9s dans d'autres applications telles que les bioc\u00e9ramiques, les mat\u00e9riaux min\u00e9raux polym\u00e8res, les carreaux de c\u00e9ramique, etc.<\/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

Les r\u00e9sidus de tungst\u00e8ne et le m\u00e9takaolin sont les principales mati\u00e8res premi\u00e8res, et le verre soluble et le NaOH sont des activateurs alcalins pour produire des mat\u00e9riaux min\u00e9raux polym\u00e8res.<\/p>\n

Il est \u00e9galement possible d'utiliser les r\u00e9sidus de flottation du tungst\u00e8ne comme mati\u00e8re premi\u00e8re pour produire des carreaux de c\u00e9ramique, ce qui permet de r\u00e9duire efficacement la temp\u00e9rature de cuisson et le co\u00fbt de production.<\/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
