Embodiment 1

[0046] like Figure 1-10 As shown, the present invention provides a scheelite flotation process for improving tungsten recovery rate, and the scheelite flotation process for improving tungsten recovery rate includes the following steps:

[0047] Step 1. Screening of mineral material: firstly remove the foreign matter inside the mineral material manually, and then use a screening device to screen out the larger and smaller impurities inside the mineral material;

[0048] Step 2, cleaning of mineral material, specifically:

[0049] Step A1. Add 20w% of modified tea saponin, 8w% of natural soap solution, 12w% of ethanol, 10w% of distilled water, 15w% of heavy cellulase and 35w% of Sapindus mucinus extract into the constant temperature mixing and stirring tank, and stir the mixture. The time is set to 18MIN, and the temperature is controlled to 63±3 degrees Celsius. After the stirred solution is cooled to room temperature, the detergent is obtained;

[0050] Step A2: Add the scr...

Abstract

The invention discloses a scheelite flotation process capable of improving the tungsten recovery rate, and relates to the technical field of scheelite extraction.The scheelite flotation process capable of improving the tungsten recovery rate comprises the following steps that firstly, mineral aggregates are screened, then, large and small impurities in the mineral aggregate are screened out through a screening device; and 2, cleaning the mineral aggregate. According to the method, the first-stage flotation column is controlled to conduct flotation work, first-stage rough concentrate containing scheelite is obtained through flotation, then the second-stage flotation column is controlled to work, second-stage rough concentrate containing scheelite is obtained through flotation, and then the second-stage rough concentrate is transferred into the regrinding device through the turnover device; the method comprises the following steps: carrying out flotation treatment on the first-stage flotation machine to enable the second-stage rough concentrate to reach a monomer dissociation state and a state suitable for flotation of the flotation machine, then controlling the first-stage flotation machine to work to float coarse scheelite particles, and finally controlling the second-stage flotation machine to work to float high-precision scheelite, so that the recovery rate of the scheelite is increased and the high efficiency of the process is improved by carrying out flotation treatment on mineral aggregates for many times.

Description

technical field [0001] The invention relates to a scheelite flotation process, relates to the technical field of scheelite extraction, in particular to a scheelite flotation process for improving tungsten recovery rate. Background technique [0002] Scheelite is a type of tungsten ore, tungsten is a metal element, silver-white crystal, hard and brittle, high melting point, can be made into very fine wire and special alloy steel: tungsten wire, ferrotungsten, tungsten steel , In the process of production of scheelite, flotation treatment of ore containing scheelite is required. The following problems exist for the prior art: [0003] 1. The recovery rate of the existing scheelite flotation process is low. Only a single flotation treatment of scheelite is carried out by a flotation machine. The rough concentrate after flotation still contains a small amount of scheelite, which is directly treated as waste. It will lead to a lot of waste of raw materials; [0004] 2. The exi...
