Abstract
The invention relates to the technical field of mineral separation, in particular to a novel tailings dewatering process which is characterized by comprising the following steps of: firstly, feeding tailings to a swirler, feeding settled sand of the swirler to a dewatering screen, feeding overflow of the swirler to a thickener, and returning undersize products of the dewatering screen to the swirler, wherein the undersize products of the dewatering screen are final products with water content of 14-16 percent; and feeding the overflow of the thickener to a clarifier, feeding underflow of the thickener to a filter press, recycling water separated from the clarifier, feeding the underflow of the clarifier to the filter press, and returning filtrate of the filter press to the thickener, wherein filter cakes of the filter press are final products with water content of 9-10 percent. The invention can realize tailings online dewatering, thereby saving funding, enabling the tailings to be directly used online, ensuring the smooth operation of subsequence works, and being beneficial to the environment protection and the production safety.
Description
Technical field
The present invention relates to the technique of preparing field, particularly a kind of tailings dewatering new technology.
Background technology
At present, the mine tailing processing mode is " thickener concentrates, and tailing dam stores ", and the space that this mode needs mine tailing to store is very big, and the Operation and Maintenance personnel are many, production management inconvenience, and directly or indirectly input is huge.Particularly in recent years,, be badly in need of a kind of new technology and make mine tailing need not enter tailing dam along with continually developing that mine tailing utilizes again, but the direct-on-line utilization.
Summary of the invention
The purpose of this invention is to provide a kind of economizing on the use of funds, realize the online dehydration of mine tailing, guarantee that subsequent job carries out smoothly, help the tailings dewatering new technology of environmental protection and production safety.
The objective of the invention is to realize by following technical proposals:
A kind of tailings dewatering new technology of the present invention is characterized in that comprising the steps:
1) at first mine tailing is fed cyclone, the sand setting of cyclone feeds dewatering screen, and the overflow of cyclone feeds thickener,
2) undersize of dewatering screen turns back to cyclone, and the oversize of dewatering screen is the final products of water content 14%-16%,
3) the thickener overflow feeds depositing reservoir, and thickener underflow feeds filter press,
4) water separated of depositing reservoir utilizes once more, and the depositing reservoir underflow feeds filter press,
5) filtrate of filter press turns back to thickener, and cake of filter-press is the final products of water content 9-10%.
Described dewatering screen is the straight line dewatering screen.
The present invention is a kind of brand-new technology; can realize the online dehydration of mine tailing; both saved fund input; reduce building tailing dam land used and construction thereof, maintenance cost; help environmental protection; the mine tailing direct-on-line is recycled: oversize can be used as building industry sand, and filter cake can be used for making materials such as pottery, glass.And guaranteed carrying out smoothly of subsequent job, help environmental protection and production safety.For enterprise has obtained remarkable economic efficiency.
