The tailing storage is one of the methods of handling tailing. The tailing storage mainly consists of the tailing transportation and the tailing stockpiling. The methods of the transportation and stockpiling are mainly determined by the particle size and the moisture content of the tailing.
The tailing processing specialists from Fote Heavy Machinery will introduce the tailing transportation and the tailing stockpiling to you in brief, which are as follows:
In general, the dry and granular tailing, produced from the gravity separation plants, can be conveyed by the skip bucket, mine car, belt conveyor, aerial cableway, or by railway. However, the slurry tailing, discharged from the flotation separation plants or the magnetic separation plants, can be generally conveyed by the slurry pump through the lifting transportation. If the terrain elevation differences are proper, the gravitational flow transportation method can be adopted. Whether you adopt the gravitational flow method or the pump transportation method can be determined according to the terrain condition. Or, the two transportation methods can be combined.
Generally, the dry and granular tailing, discharged from the gravity separation plants, can be directly piled into tailing pile or be directly piled in the valley. The slurry tailing, discharged from the magnetic separation or gravity separation plants, should be transported to the tailing storehouse. However, there are several types of the building location of the tailing storehouse. For example, if the building location of the tailing storehouse is surrounded on three sides by high mountains, a transverse dam can be built at the head of the valley; If the building location is on the hillside, the dam can be built on three sides; If it sits on the ground, the dam should be built on all sides. But, the most common building location of the tailing storehouse is that it is surrounded on three sides by high mountains. It is mainly because the dam body is short. And the construction scale of the primary dam is small. Besides, it is easy to build the dam of the tailing pile during the production time. But, at this kind of terrain, the ponding area is large, which may lead to the increase of the volume of flood flow.
