Embodiment Construction

[0007] The present invention will be further described below in conjunction with embodiment:

[0008] In the traditional iron ore positive flotation, the fatty acid collector is a mixture of different carbon chain fatty acids and their salts, which use carboxylate as a chemical bond to interact with iron minerals, and the effect is weak. The invention introduces a hydroxyl group on the first carbon atom next to the carboxylate group of the fatty acid collector, so that the hydroxyl group and the carboxylic acid group form a conjugate effect. In the action of iron minerals, this conjugation effect forms a chelation effect when it interacts with iron minerals, which greatly increases the adsorption of iron minerals and collectors, so that the collectors can absorb iron minerals The harvesting capacity is significantly increased.

Abstract

The invention provides a chelate collector for flotation of iron mineral, which is characterized in that alpha-hydroxyl-13-fatty acid and carbon chain alpha-hydroxyl-fatty acids having carbon chain lower than that of the alpha-hydroxyl-13-fatty acid account for 18 to 21 percent of the total content of the alpha-hydroxyl-fatty acid; alpha-hydroxyl-17-fatty acid and carbon chain alpha-hydroxyl-fatty acid having carbon chain higher than the alpha-hydroxyl-17-fatty acid account for 18 to 21 percent of the total content of the alpha-hydroxyl-fatty acid; and alpha-hydroxyl-14-fatty acid, alpha-hydroxyl-15-fatty acid and alpha-hydroxyl-16-fatty acid account for 58 to 62 percent of the total content of the alpha-hydroxyl-fatty acid. Compared with the prior chelate collector for flotation, the chelate collector has the advantages of high mineral processing efficiency, few species of used reagents and simple preparation.

Description

technical field [0001] The invention relates to the field of iron ore beneficiation and flotation, in particular related to the iron ore flotation collection agent. Background technique [0002] In the iron ore beneficiation process in my country, flotation is an effective beneficiation method. Since the 1950s, my country began to rely on the method of positive flotation to sort iron ore. However, while positive flotation of iron ore achieves better beneficiation indicators, it also has relatively weak collection capacity due to the use of fatty acid collectors in positive flotation, which relies on the interaction between carboxylate ions and iron minerals. relatively low issue. At the end of the 1990s, my country successfully studied the iron ore reverse flotation process, which has a high beneficiation efficiency and has been widely promoted and applied throughout the country. Although the iron ore reverse flotation process has high beneficiation efficiency, there are ...
