Problems and Countermeasures of comprehensive utilization of tailings

2016-06-29

(1) the utilization of tailings is low, and the comprehensive utilization rate is low.
At present, the vast majority of tailings have not been comprehensive utilization, comprehensive utilization rate of less than 10%, especially the utilization of iron tailings and non-ferrous metal tailings is lower. With the continuous increase of mineral resources in China, tailings discharge will continue to increase every year, to speed up the comprehensive utilization of tailings is imminent.
(2), the basic work is weak, lack of data support
In the statistical system of China’s economic development, there is no comprehensive utilization of resources on the basis of statistics, there is no comprehensive utilization of tailings data statistics. Is not conducive to scientific policy measures, but also not conducive to the actual situation of the policy measures to make timely adjustments.
(3) the comprehensive utilization of tailings comprehensive utilization of technical research investment is not enough
At present, the lack of investment in the development of comprehensive utilization of tailings comprehensive utilization of key technologies of the power and enthusiasm. At the same time, the state in tailings comprehensive use of forward-looking technology in the development of inadequate investment, leading to most of the tailings comprehensive utilization process only stay in the simple technology, lack the ability to make efficient utilization of tailings and bulk high value utilization of original technology research and development.
(4), the existing policy support is not enough
China in the comprehensive utilization of resources have some preferential tax policies, but due to the comprehensive utilization of tailings and ore mining compared, resource grade low utilization of high cost, and has good social benefit, economic benefit is poor, existing resources comprehensive utilization policy lack of targeted, the support is insufficient, so the enterprise utilization of tailings enthusiasm is not high.
(5) the tailings dewatering equipment produced by Longzhong is of great significance in the relief of tailings, more and more mining enterprises began to use tailings dewatering equipment to deal with tailings.
