Abstract

The invention relates to a low-grade iron mineral flotation collecting agent, which consists of alpha hydroxyl-fatty acids and beta hydroxyl-fatty acids, namely 14 to 16 weight percent of total components of alpha hydroxyl-below-dodecyl carbon chain alpha hydroxyl-fatty acid, alpha hydroxyl-dodecyl fatty acid and alpha hydroxyl-tridecyl fatty acid, 4 to 6 weight percent of total components of beta hydroxyl-below-dodecyl fatty acid, beta hydroxyl-dodecyl fatty acid and beta hydroxyl-tridecyl fatty acid, 14 to 16 weight percent of total components of alpha hydroxyl-heptadecyl fatty acid, alpha hydroxyl-octadecyl fatty acid and over-octadecyl carbon chain alpha hydroxyl-fatty acid, 4 to 6 weight percent of total components of beta hydroxyl-heptadecyl fatty acid, beta hydroxyl-octadecyl fattyacid and over-octadecyl carbon chain beta carbon chain hydroxyl-fatty acid, 39 to 41 weight percent of total components of alpha hydroxyl-tetradecyl fatty acid, alpha hydroxyl-pentadecyl fatty acid and alpha hydroxyl-hexadecyl fatty acid, and 19 to 21 weight percent of total components of beta hydroxyl-tetradecyl fatty acid, beta hydroxyl-pentadecyl fatty acid and beta hydroxyl-hexadecyl fatty acid. By the low-grade iron mineral flotation collecting agent, technical indexes such as over 66.0 percent of concentrate grade and over 82 percent of operation recovery rate can be obtained, and the operation recovery rate can be improved by 10 to 14 percent.

Description

technical field [0001] The invention relates to the technical field of iron ore beneficiation and flotation, in particular to a low-grade iron ore flotation collector. Background technique [0002] Flotation is one of the effective beneficiation methods for iron ore. Since the 1950s, the iron ore flotation method has been widely used in my country. However, the collection capacity of the applied iron ore flotation collector is weak, and the beneficiation efficiency is relatively low. At the end of the 1990s, my country successfully studied the iron ore reverse flotation process, and the beneficiation efficiency was relatively high. However, the medicament itself has many types and complex preparation problems. The low-grade iron ore flotation collector formula proposed this time unifies the advantages of high beneficiation efficiency of iron ore reverse flotation process and iron ore forward flotation process with fewer reagents and simple preparation. It is our iron ore ...
