Tailings sand making is feasible, which can alleviate the shortage of sand and gravel resources and has a wide range of applications, including building materials, permeable bricks, etc. It can be efficiently processed through reasonable technical configuration. Tailings are not only waste, but also potential resources that can promote the green economy.

With the rapid development of mining and sand and gravel production projects, the accumulation of a large number of metal tailings has become an environmental hazard. Although all regions have begun to pay attention to the treatment of mine waste rock, other treatment methods have limited effectiveness except landfill. However, with the rise of machine-made sand and construction waste recycling, more and more people have begun to pay attention to the possibility of tailings sand making. Since construction waste can be recycled, can tailings also become a new raw material for sand making?

The feasibility of metal tailings sand making

Although tailings are the residues after ore processing, they are similar in composition to ordinary stones. The difference is that the content ratio of certain minerals has changed, which has a certain impact on the quality of machine-made sand, but this does not hinder its use as sand and gravel aggregates. For example, the metal tailings left after the extraction of metals from metal ores such as iron ore, copper ore, and zinc ore can be used for municipal road paving, environmentally friendly brick production, urban greening and other projects. This not only alleviates the problem of tight sand and gravel resources, but also leaves room for high-quality sand and gravel resources for use in engineering construction with higher requirements.

Wide application of metal tailings sand making

The application range of metal tailings sand making is very wide. In addition to being used in general building material production, tailings can also be used to make permeable bricks, environmentally friendly bricks, block bricks and other products, effectively reducing dependence on natural sand and gravel. Through reasonable technical configuration, tailings can not only be effectively utilized, but also become a new investment direction.

Production process of metal tailings sand making

The production process of metal tailings sand making usually includes three stages: coarse crushing, medium crushing and sand making. According to the type and demand of tailings, select the appropriate process flow and equipment. The main equipment includes jaw crusher, cone crusher, sand making machine and sand washing machine. Different types of tailings need to select a suitable combination of equipment according to their hardness and purpose, so as to achieve efficient and low-consumption treatment effects.

Environmental value of metal tailings

Metal tailings are not only waste, but also a potential resource. With the continuous advancement of mining machinery technology, the recycling value of tailings has been gradually discovered and has become a high-quality raw material for the production of building materials. Through tailings sand making, not only can a large amount of natural stone be saved, but also environmental pollution can be reduced and energy can be saved. Tailings have broad application prospects in the fields of environmentally friendly building materials, road paving, anti-slip materials, etc., which can save a lot of resources every year and promote the development of the green economy.
