Processing system for separating barite from tailings and method of processing system

Abstract

The invention relates to a processing system for separating barite from tailings. The system includes PE compound pendulum jaw crushers I and II connected together, a roller machine and a vibrating screen. The raw ore particle outlet with particle size ≥ 3mm and particle size < 3mm is set on the vibrating screen; the raw ore particle discharge port with particle size ≥ 3mm is connected to the roller machine; the raw ore particle discharge port with particle size < 3mm is connected to the silo; A feeder is installed at the bottom of the silo, and the end of the feeder is connected with a jig; a sprinkler is installed above the jig, one side is connected with a sedimentation tank and a purification tank, and two water separators with water separator I are installed at the bottom; The dryer with water separator Ⅰ and water separator Ⅱ; the top of the dryer is equipped with a cyclone dust collector, and the bottom is equipped with a dry concentrate discharge port; one side of the water separator is equipped with a main water tank with a water flow adjustment plate and an overflow adjustment The water distribution tank of the plate; the bottom of the water distribution tank is equipped with a powder concentrate sedimentation tank, and the powder concentrate sedimentation tank is connected with a suction sand pump; the sedimentation tank is connected with the purification tank. The invention also discloses the processing method of the system. The invention has little pollution and high purity of the obtained concentrate.

Description

technical field [0001] The invention relates to the technical field of barite processing, in particular to a processing system and method for separating barite from tailings. Background technique [0002] Barite (BaSO 4 ) is an important barium-containing mineral, which has the characteristics of large specific gravity (4.3~4.7), low hardness (3~3.5), stable chemical properties, insoluble in water and acid, and is mainly used in petroleum, chemical industry, paint, filler 80%~90% of which are used as mud weighting agents in oil drilling. [0003] The choice of barite beneficiation method is affected by the type of ore, the nature of the raw ore, the scale of the mine, and its use. The main beneficiation methods currently used are shown in Table 1: [0004] Table 1: Main beneficiation and processing methods of barite [0005] [0006] For the residual type barite ore, the gravity separation method is generally used for separation, that is, the barite concentrate is sel...
