Embodiment Construction

[0013] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0014] Depend on figure 1 Provide, the bauxite positive flotation water treatment method of the present invention is:

[0015] 1) In the main water system, the crushed and homogenized bauxite enters the high-pressure roller mill through the upper chamber, and the ore powder after the roller mill passes through the vibrating screen. Among them, the ore powder that cannot pass through the 6-mesh sieve passes through the high-pressure roller mill again Machine roller mill, the ore powder that can pass through the 6-mesh sieve enters the ball mill, and adds circulating water and sodium carbonate solution in the circulating pool. The amount of circulating water added is 1-1.5 times the weight of the ore powder, and the mixture is discharged from the ball mill. The mixture The feeding pump of the cyclone enters the cyclone, and after...

Abstract

The invention relates to a treatment method for direct flotation water of bauxite, aiming at solving the problems that the existing treatment method is not thorough in the treatment of the mineral separation backwater of bauxite, high in cost, complex in treatment process, and available in secondary pollution. The treatment method adopts a water treatment system which consists of a main water system, a first water treatment passageway and a second water treatment passageway. The treatment method comprises the following steps of: firstly, producing tailings pulp and concentrate pulp by the main water system; respectively carrying out water treatment on the tailings pulp and the concentrate pulp by a double-passageway pH valve balancing purifying method; and keeping the pH value balance of the water in a circulating water tank. The treatment method adopts three water treatment systems such as the main water system, the first water treatment passageway and the second water treatment passageway, so that the problems that the existing treatment method is not thorough in the treatment of the mineral separation backwater of bauxite, high in cost, complex in treatment process, and available in secondary pollution can be solved.

Description

technical field [0001] The invention relates to a method for treating bauxite positive flotation water. Background technique [0002] my country's bauxite beneficiation technology began in the 1970s. The first industrial test of bauxite flotation was carried out in Xiaoguan Aluminum Mine of China Great Wall Aluminum Corporation in 2000. The first industrial production line was established in Chinalco Zhongzhou Branch in 2002. The grafted alumina production process was put into operation. At present, the bauxite beneficiation production is based on the grafted alumina production process, using the bauxite positive flotation method, and the main characteristics of using the bauxite positive flotation desiliconization are: [0003] 1. Fatty acid salts are used as collectors, and soda ash and sodium hexametaphosphate are used as regulators; [0004] 2. The particle size distribution of grinding products is polarized, and over-grinding and muddying are serious. [0005] The cur...
