Embodiment Construction

[0017] A collector for bauxite flotation, the chemical composition of which is a compound of industrial fatty acids, naphthenic acid and hydroxamic acid, and the mass percentage of the compound is 25-98:0- 75: 0-25. The fatty acid in the compound is soybean oil or cotton oil. The fatty acid in the compound is essential oleic acid or common oleic acid. The naphthenic acid in the compound comes from alkali slag. After acidifying with concentrated sulfuric acid at a temperature of 70-80°C, naphthenic acid is precipitated and floats on the upper layer. After separation, naphthenic acid with a purity of more than 90% is obtained . The hydroxamic acid in the complex is an alkyl hydroxamic acid.

[0018] Below in conjunction with example the present invention will be further described:

[0019] The comprehensive sample of low-grade bauxite in Xiaoyi, Shanxi was used as the test sample, and its chemical composition is shown in Table 1.

Abstract

The present invention relates to one kind of collecting agent for floating and desilicating bauxite, and the collecting agent consists of industrial chemicals fatty acid, naphthenic acids and hydroximic acid in the weight ratio of 25-98 to 0-75 to 0-25. The re-compounded collecting agent features the mutual solubilization and homogenization of its components and no negative effect of emulsifier. The naphthenic acids have cyclopentyl formic acid with smelting point of -7 deg.c as the main component, and are suitable for low temperature use. The collecting agent is suitable for for floating and desilicating bauxite of different types, especially low grade bauxite, and has high collecting performance, low consumption and good low temperature use effect.

Description

technical field [0001] The invention relates to a collector for bauxite flotation desiliconization. technical background [0002] Most of the bauxite resources in my country are low-to-medium-grade diaspore-type bauxite, which cannot be directly applied to the Bayer process with low production costs. It needs to be desiliconized by beneficiation to increase its aluminum-silicon ratio. After the 9th Five-Year Plan, the 10th Five-Year Plan, and the National 973 and other scientific and technological breakthroughs, the bauxite flotation desiliconization technology and process have been developed rapidly, and good results have been achieved. It has been proved to be the most effective and economical method. [0003] Collector is the most critical technology for mineral flotation separation. The surface physical and chemical properties of useful minerals and gangue minerals are changed by flotation reagents, and the buoyancy of minerals is adjusted to create conditions that usef...
