As a component of products in the mineral processing industry, tailings have little value. However, Xinhai experts express that tailings have great potential to be explored.
There is a problem in mineral processing, which is how to cater for the national policies and how to effectively deal with tailings with a low cost. According to the tailings disposal, the governments published the relevant policies to direct the tailings disposal.
It was reported that there were about 14 billion tons of tailings by the end of 2011. Only in 2007, there were 1 billion tons. The large amount of tailings brings a series of problems for the national resources, environment, security and lands and so on. However, the bigger the pressure is, the bigger the potential of development and utilization is.
At this point, the main problem is the low utilization of the tailings. Many areas still have no sense of tailings dry stacking, which stops the development of relevant pollution control work. In addition, fewer investments are also one of that. Thus, Yantai Xinhai Mining Machinery Company developed a set of innovative technologies to deal with tailings. It is the first domestic company who developing tailing dry stacking technology and equipment. In 2009, Xinhai started developing the third generation tailing dry stacking technology and equipment — hydro-cyclone, high efficiency thickener and high efficiency multi-frequency dewatering screen. This technology has the features of low investment, low running cost, high efficiency and low energy consumption. It is much better than other domestic tailing dry stacking technology.
Tailing dry stacking is a new tailing treatment technology. In the dry stacking method, filters and vacuum presses remove more of the water, which can be recycled for process water, reused in the flotation step for instance. Typically, dry tails contain less than 25% water. Dry tails are transported to the tailing piles by conveyor belt or truck, then dumped and compacted. Tails don’t need a containment structure and are more stable. Dry stacked tailings are essentially immune to geotechnical “failure???and can be designed to withstand static and seismic forces. Because there is much less water in the tails, there is less chance of seepage. In the future, tailing dry stacking is the only way for the mining industry.
Whether in the technologies or in the products, Xinhai did its utmost to meet the requirements of the customers. Therefore, the tailings dry stacking with high efficiency and energy saving is the preferred choice for the customers.
Xinhai automatic flotation control system can be applied to metal mines, nonferrous metal mines and nonmetallic minerals. It mainly contains pulp density, the amount of reagent. ... [more]
