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.
[0009] Mechanism of Chelation Collectors and Iron Minerals
[0010] Iron minerals contain Fe 3+ , Fe 3+ The strong interaction with water molecule...
