Problems solved by technology

[0003] As far as the existing flotation machine separation process is concerned, there are mainly three problems in the following aspects: ① The separation effect on fine-grained minerals is not good
②The process is long, the process is complicated, and the operating cost is high
③The equipment is large in size, covers a large area, and requires high construction investment

Embodiment Construction

[0020] Hereinafter, the flotation recovery method of fine-grained ilmenite according to an exemplary embodiment of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that, in this specification, unless otherwise specified, the percentages involved refer to percentages by weight.

[0021] The specific idea of ​​the present invention is to use a cyclone-static micro-bubble flotation column for flotation, and provide a new and effective flotation recovery method for fine-grained ilmenite by optimizing the process flow and reagent system.

[0022] Such as figure 1 As shown, the flotation recovery method of fine-grained ilmenite according to an exemplary embodiment of the present invention includes the following steps: 1) roughing the flotation raw ore through the first cyclone-static micro-bubble flotation column, and using Sulfuric acid is used as regulator, and MOH and diesel oil are used as collectors to obtain rou...

Abstract

The invention discloses a flotation recovery method of micro-fine particle ilmenite. The flotation recovery method of the micro-fine particle ilmenite comprises the steps that (1) rougher flotation is carried out on flotation raw ore through a first rotational flow-static microbubble flotation column, sulfuric acid is adopted as regulators, MOH and diesel oil serve as collecting agents, and rougher tailings and rougher concentrate are obtained; (2) the rougher concentrate is sent to a second rotational flow-static microbubble flotation column for cleaner, the sulfuric acid is adopted as the regulators, cleaner tailings and cleaner concentrate are obtained, the cleaner concentrate is the final concentrate, and the flotation raw ore comprises more than 50wt% micro-fine particle ilmenite with the granularity being below 74 micrometers. The micro-fine particle ilmenite difficult to float is recovered through a rougher floatation process and a cleaner floatation process with the flotation columns, the technological process is simpler, and meanwhile the separation indexes of the ilmenite can be met.

Description

technical field [0001] The invention relates to a beneficiation method, in particular to a method for flotation recovery of fine-grained ilmenite. Background technique [0002] At present, industrialized ilmenite separation is a separation process with flotation machines as the main equipment. The main structure and separation mechanism of adjacent flotation cells in the mineral separation system of conventional flotation cells are basically the same. A nearly linear sorting process, not compatible with non-linear changes in mineral composition and properties during sorting. [0003] As far as the existing flotation machine separation process is concerned, there are mainly three problems in the following aspects: ① The separation effect on fine-grained minerals is not good. ② The process is long, the process is complicated, and the operating cost is high. ③ The equipment is large in size, covers a large area, and requires high construction investment. [0004] Therefore,...
