Problems solved by technology

[0003] However, the recovery rate of the current flotation column is not ideal, and the tailing is still high. Technically, it is believed that the chemical concentration in the slurry will increase when the flotation column is working and the slurry is settling from top to bottom. In this way, it is not conducive to the mineralization of air bubbles in the lower part of the flotation column, because it is close to the tailings discharge outlet at the bottom of the flotation column, and the uncaptured and adsorbed minerals will be discharged soon, so it will cause Mineral running tail is high

Abstract

The invention discloses a reagent adding system of a flotation column and a reagent adding method of the flotation column. The reagent adding system of the flotation column comprises a reagent adding controller and a reagent atomizing foam maker. In the reagent adding state, a high pressure air source is opened, reagents are injected into the reagent adding controller from an upstream reagent box, pressurized through the reagent adding controller to be injected into the reagent atomizing foam maker, and mixed and atomized with high-speed flow air in the reagent atomizing foam maker, and then jetted into the bottom of the flotation column by overcoming the self-pressure of the flotation column along with high pressure air to add the reagents. According to the reagent adding system of the flotation column and the reagent adding method of the flotation column disclosed by the invention, flotation reagents can be fully atomized through designs of the reagent adding controller and the reagent atomizing foam maker before pulp is added to improve the effective utilization rates of the reagents.

Description

technical field [0001] The invention relates to the field of mine beneficiation, in particular to a flotation column dosing system and a dosing method. Background technique [0002] In the current flotation process, the reagents are first added to the pulp for stirring and mixing, and then enter the flotation process. In the application of the flotation column, the slurry mixed with chemicals flows in from the upper part of the flotation column, and forms contact with the air bubbles that are filled and floated from the bottom of the flotation column during the process of sinking itself, and the target minerals will be attached to the flotation column. The bubbles float up and overflow, and finally complete the beneficiation. [0003] However, the recovery rate of the current flotation column is not ideal, and the tailing is still high. Technically, it is believed that the chemical concentration in the slurry will increase when the flotation column is working and the slurry...
