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

Debido a la erosi\u00f3n, las escombreras contienen una gran cantidad de cuarzo<\/a>, feldespato<\/a>anf\u00edbol, piroxeno, calcita, dolomita, minerales de silicato y magnesio.<\/strong> Los principales componentes qu\u00edmicos son silicio, aluminio, calcio y magnesio. etc.<\/strong>en los que el contenido de silicio y aluminio es m\u00e1s elevado. Por lo tanto, es esencial utilizar plenamente los recursos de los residuos, especialmente los recursos no met\u00e1licos que contienen.<\/p>\n

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

En la actualidad, el principal m\u00e9todo de eliminaci\u00f3n de residuos mineros es el almacenamiento de est\u00e9riles, que ocupar\u00e1 una gran cantidad de terrenos agr\u00edcolas y forestales y destruir\u00e1 la asignaci\u00f3n de recursos terrestres en la zona donde se ubique. Adem\u00e1s, algunas plantas de procesamiento minero situadas en zonas remotas o plantas de procesamiento a peque\u00f1a escala situadas en ciudades verter\u00e1n los est\u00e9riles directamente en el entorno natural, causando importantes da\u00f1os medioambientales. Es urgente consumir los est\u00e9riles mediante diversos m\u00e9todos de aprovechamiento integral.<\/p>\n

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

Para proteger los recursos minerales, mantener el equilibrio ecol\u00f3gico y poner en marcha un c\u00edrculo virtuoso, los pa\u00edses industrialmente desarrollados del mundo han empezado a construir \"industrias de materias primas secundarias\" y han logrado resultados notables. Los est\u00e9riles almacenados en mi pa\u00eds suelen ser de mayor calidad, sobre todo los de los a\u00f1os 50 y 60, que tienen un mayor valor de desarrollo y utilizaci\u00f3n. Adem\u00e1s, en comparaci\u00f3n con el desarrollo de nuevas vetas, el coste de exploraci\u00f3n de los est\u00e9riles es menor, y los resultados de la exploraci\u00f3n son m\u00e1s precisos. Al mismo tiempo, el transporte por balsa de est\u00e9riles<\/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

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

La cantidad total de residuos es grande y hay muchos tipos. Los siguientes est\u00e9riles de hierro, de cobre, de plomo-zinc y de tierras raras<\/strong> como ejemplos para introducir:<\/p>\n

Para la separaci\u00f3n secundaria de est\u00e9riles de hierro<\/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

Para est\u00e9riles de cobre<\/strong><\/em>los m\u00e9todos de separaci\u00f3n secundaria incluyen agente reductor proceso de tostaci\u00f3n-molienda-separaci\u00f3n magn\u00e9tica, flotaci\u00f3n y lixiviaci\u00f3n<\/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

Los grados de plomo<\/a>, 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
