The tailings contain all kinds of valuable components such as ferrous and non-ferrous minerals, rare and precious and non-metallic minerals, so that they actually are valuable secondary mineral resources. After recycling valuable components from tailings, the main mineral components in the rest tailing are often used as compound mineral raw materials for building material, ceramics and glass ceramics industry. In a word, after a series of processing and multi-stage utilization, tailing resources can be fully used to bring benefits to human beings.

In the past, the tailings are often stocked, which not only pollutes the environment, but has safety hazards. To accelerate the comprehensive utilization of resources and energetically develop cyclic economy, tailings will become a big burden for social and economic development if not properly developed and used. The comprehensive utilization and deep development of tailing resources have become a focus of national resources exploration.

Thereinto, another advantage of developing artificial sand with tailings is that the artificial sand is generally produced by the machinery and has fixed production site and improved organization and management, which is insufficient for most artificial sand manufacturing companies. That building sand and stone should provide product qualification certificate has been said many years in the relevant standard of sand and concrete, but it remains to be implemented. Through the exploration of tailing artificial sand, this problem may be solved, which has active meaning to improve the quality of the whole sand and stone industry.

As for the comprehensive use and recycling of tailing resources, impact crusher produced by Huahong Machinery is the first choice. Based on the profound knowledge of the development and utilization of tailings and profound research on artificial sand making technology and combining with foreign advanced technology, Hongxing Machinery researches and develops and manufactures VI series vertical shaft impact crusher, which can also be called sand maker, which has multiple independent patents and property rights. It is another breakthrough made in the sand aggregate production equipment manufacturing field and it is not only provide excellent sand aggregate for high-rise building, highway, water and electric dam construction and national key projects construction and concrete mixing station, but has wide application in slag disposal and metal ore crushing fields.

The comprehensive utilization of tailing resources is the focus of breaking through in mining development and introduces a scientific and technical development road of “integrating resources, depth development, comprehensive use and cyclic development”.
