AI Technical Summary

Technical Problem

The existing slurry and tailings conveying systems have problems that it is difficult to meet the production needs of each step, especially when coarse-grain tailings enter the tailings conveying system, which affects the service life and operating rate of the diaphragm pump.

Method used

A system for conveying slurry inside the mine area is designed, including multiple subsystems, using multiple slurry pumps and wear-resistant pipelines for transportation, and slag separation equipment is installed between the concentrated tailings and the tailings feeding pump pool. A flexible screen is used to screen the tailings slurry before entering the feeding pump pool to ensure that the coarse particle tailings do not enter the tailings conveying system.

Benefits of technology

It effectively solved the problem of coarse particle tailings entering the tailings conveying system, extended the service life of the diaphragm pump, improved the operating rate, and achieved further mechanization and comprehensive utilization of tailings.

Abstract

The invention discloses a system for conveying ore pulp in a mining area, which is characterized in that an ore pulp conveying starting point is a raw ore lifting pump pool, and a conveyed material is underflow of a thickener; a raw material conveying subsystem, a strong magnetic rough concentrate lifting subsystem, a secondary iron ore concentrate lifting subsystem, a first gravity concentration and rough concentration feeding subsystem, a second gravity concentration and rough concentration feeding subsystem, a first gravity concentration and fine concentration feeding subsystem, a second gravity concentration and fine concentration feeding subsystem, a third gravity concentration and fine concentration feeding subsystem, a fourth gravity concentration and fine concentration feeding subsystem, a strong magnetic scavenging feeding subsystem, a tailing concentration subsystem, a tailing conveying subsystem and a concentrate conveying subsystem are adopted for treatment. Oversize products are piled and sold as gravel aggregates, undersize ore pulp automatically flows into a high-intensity magnetic roughing operation, and sorted tailings automatically flow into a tailing feeding pump pool of a diaphragm pump in a tailing workshop of a dressing plant, so that the aims of effectively reducing the loss of the tailings, reducing the workload of a settling pond, reducing the cleaning cost of the settling pond and reducing the natural piling time of the tailings are achieved; meanwhile, the economic benefit is increased.
