Treatment system for concentration tank of iron ore concentrates

Abstract

The invention relates to a treatment system for a concentration tank of iron ore concentrates. The treatment system comprises the concentration tank, a concentration tank overflow tank, a central distribution barrel and ore concentrate pipelines, wherein output ports of the ore concentrate pipelines are connected with the central distribution barrel; the concentration tank is arranged at the outer side of the central distribution barrel; the concentration tank overflow tank is arranged at the outer side of the concentration tank; the ore concentrate pipelines are composed of a plurality of thin ore concentrate pipelines and a plurality of thick ore concentrate pipelines; the plurality of thin ore concentrate pipelines are communicated with the plurality of thick ore concentrate pipelines through a fed ore distribution box; the number of the thin ore concentrate pipelines is larger than that of the thick ore concentrate pipelines; and one ends of the thick ore concentrate pipelines are connected with the central distribution barrel, and the other ends of the thick ore concentrate pipelines are connected with the fed ore distribution box. The ore concentrate pipelines are composed of the thin ore concentrate pipelines and the thick ore concentrate pipelines, so that the ore feeding flow rate is reduced to ensure that the content of solid particles in overflow water cannot exceed the standard under the condition that the concentration tank operates over a design, and furthermore, the treatment capacity of the concentration tank is enhanced, and the content of the solid particles in the overflow water is reduced.

Description

technical field [0001] The invention relates to a processing system for an iron concentrate concentration pool. Background technique [0002] Yunnan Dahongshan Pipeline 22-meter concentration pool has an ore concentration of 20% to 30% and an output concentration of 65% to 70%. It was built in 2006 and is one of the supporting projects for 4 million tons of mining, dressing and pipelines, with a designed processing capacity of 230 10,000 tons / year, the daily processing capacity is 7,200 tons, and the solid content in the overflow water is ≤200 mg / liter. During the three years from January 1, 2007 to 2009, Yunnan Dahongshan pipeline transported 1.116 million tons in 2007, 1.851 million tons in 2007, and 2.26 million tons in 2008. Within the range of the designed delivery capacity of 2.3 million tons, the solid content in the overflow water of the thickening tank is below 200 mg / L. [0003] With the continuous development of Kunming Iron and Steel Group Corporation, Dahongsh...

AI Technical Summary

Problems solved by technology

[0005] The present invention designs an iron ore concentrate concentration pool treatment system, which solves the technical problem that the existing iron ore concentrate concentration pool treatment system has excessive solid particle content in the overflow water due to the increase of ore load, which makes the concentration pool treatment lack of ability
