Tailings, the low-value byproducts of mineral processing, constitute a major portion of industrial solid waste. Despite their limited economic viability in production, they hold significant untapped potential. With massive global mining operations for metals, coal, and non-metallic ores<\/strong>, tailings accumulate in enormous quantities\u2014posing environmental and safety risks while hindering sustainable mining practices.<\/p>\n

Comprehensive tailings utilization offers a solution to these challenges while unlocking new revenue streams for mining companies. Below, we explore the benefits of tailings repurposing and the most effective methods to achieve it.<\/p>\n

Why Should Tailings Be Put to Comprehensive Use?<\/h2>\n

Why should tailings be comprehensively utilized? We will explain this through the following four points:<\/strong><\/p>\n

1. Recyclable Resources are Abundant in Tailings<\/h3>\n

China’s main types of ore are co-associated ores, which account for 80% of the total mineral resources and are difficult to separate. In addition, the beneficiation and smelting technology of the early mines was relatively backward, and the economic conditions in different periods were also different. Usually, it could recover only one or some minerals in the ore. It makes non-ferrous, rare, precious metals, and many non-metallic minerals that remain in the tailings. They can be recycled and utilized with the current beneficiation technology to supplement the increasingly depleted mineral resources.<\/p>\n

2. Non-metal Resources are Abundant in Tailings<\/h3>\n

En raison de l'\u00e9rosion, les r\u00e9sidus contiennent une grande quantit\u00e9 de quartz<\/a>, feldspath<\/a>amphibole, pyrox\u00e8ne, calcite, dolomite, min\u00e9raux silicat\u00e9s et magn\u00e9sium.<\/strong> Les principaux composants chimiques sont le silicium, l'aluminium, le calcium et le magn\u00e9sium, etc.<\/strong>dans lesquels la teneur en silicium et en aluminium est plus \u00e9lev\u00e9e. Il est donc essentiel d'utiliser pleinement les ressources des r\u00e9sidus, en particulier les ressources non m\u00e9talliques qu'ils contiennent.<\/p>\n

3. Environmental and Safety Hazards Demand Action<\/h3>\n

Actuellement, la principale m\u00e9thode d'\u00e9limination des r\u00e9sidus est le stockage des r\u00e9sidus, qui occupe une grande partie des terres agricoles et foresti\u00e8res et d\u00e9truit l'affectation des ressources fonci\u00e8res dans la r\u00e9gion o\u00f9 il est situ\u00e9. En outre, certaines usines de traitement minier situ\u00e9es dans des r\u00e9gions \u00e9loign\u00e9es ou des usines de traitement \u00e0 petite \u00e9chelle situ\u00e9es dans des villes d\u00e9versent les r\u00e9sidus directement dans l'environnement naturel, causant ainsi des dommages environnementaux importants. Il est urgent d'utiliser les r\u00e9sidus par le biais de diverses m\u00e9thodes d'utilisation compl\u00e8tes.<\/p>\n

4. High Economic Potential of Reprocessing<\/h3>\n

Pour prot\u00e9ger les ressources min\u00e9rales, maintenir l'\u00e9quilibre \u00e9cologique et mettre en \u0153uvre un cercle vertueux, les pays industriellement d\u00e9velopp\u00e9s du monde ont commenc\u00e9 \u00e0 construire des \"industries de mati\u00e8res premi\u00e8res secondaires\" et ont obtenu des r\u00e9sultats remarquables. Les r\u00e9sidus stock\u00e9s dans mon pays ont g\u00e9n\u00e9ralement des teneurs plus \u00e9lev\u00e9es, en particulier les r\u00e9sidus des ann\u00e9es 1950 et 1960, qui ont une plus grande valeur de d\u00e9veloppement et d'utilisation. En outre, par rapport \u00e0 l'exploitation de nouveaux filons, le co\u00fbt d'exploration des r\u00e9sidus est moins \u00e9lev\u00e9 et les r\u00e9sultats de l'exploration sont plus pr\u00e9cis. En m\u00eame temps, le transport autour des bassin de d\u00e9cantation<\/strong> is convenient, and the infrastructure is relatively complete, which can make a large investment in infrastructure. The tailings in the tailings pond are relatively loose and fine in particle size. Only a small amount of crushing and grinding operations are required; the energy consumption is low, and the production cost is low.<\/p>\n

Quelles sont les m\u00e9thodes d'utilisation des r\u00e9sidus ?<\/h2>\n

1. Secondary Mineral Separation<\/h3>\n

La quantit\u00e9 totale de r\u00e9sidus est importante et il en existe de nombreux types. Voici ce qui se passe r\u00e9sidus de fer, r\u00e9sidus de cuivre, r\u00e9sidus de plomb-zinc et r\u00e9sidus de terres rares<\/strong> comme exemples \u00e0 pr\u00e9senter :<\/p>\n

Pour la s\u00e9paration secondaire des r\u00e9sidus de fer<\/strong><\/em>, there are already relatively mature processes to recover the iron minerals in them and obtain iron concentrates of better quality. Because of the weak magnetic properties of iron tailings, pre-concentration-magnetic separation-reverse flotation and magnetization roasting-magnetic separation processes have become popular secondary separation methods for iron tailings. These two methods have low TFe grades. The treatment effect of iron tailings with fine embedded particle size is relatively significant; the iron grade of the obtained concentrate products is generally between 55% and 67%, the recovery rate of metallic iron is high, and the products have high economic value.<\/p>\n

Pour r\u00e9sidus de cuivre<\/strong><\/em>Les m\u00e9thodes de s\u00e9paration secondaire comprennent agent r\u00e9ducteur r\u00e9duction torr\u00e9faction-broyage-s\u00e9paration magn\u00e9tique, flottation et lixiviation<\/strong>. The reduction roasting-grinding-magnetic separation process reduces metals such as copper and iron in the copper tailings into metal elements by reducing agents, grinding them into fine particles, and finally, using magnetic separation for recovery. Flotation can achieve secondary separation of valuable components in copper tailings using different procedures and reagents. The chemical leaching process can realize the recovery and utilization of various valuable metals in copper tailings.<\/p>\n

Les grades de plomb<\/a>, le zinc<\/a>, and other metals in lead-zinc tailings are relatively high and have high recovery values, so their secondary sorting is meaningful. There are many types of secondary beneficiation methods for lead and zinc tailings. In addition to the traditional beneficiation process, there are many new technologies. Such as:<\/p>\n
