Efficient collecting agent for ilmenite and preparation method thereof

Abstract

The present invention relates to an efficient collecting agent for ilmenite and a preparation method thereof. The efficient collecting agent for ilmenite comprises the following components in percentage by weight: 58-62% of rosin, 18-20% of sodium hydrogen sulfite, 11-13% of ethanolamine and 7-9% of alkyl sulfonate. The preparation method of the efficient collecting agent for ilmenite provided inthe present invention comprises: pouring the rosin in the foregoing parts by weight into a reaction kettle, and adding the sodium hydrogen sulfite in foregoing parts by weight thereto for reacting at70-80 DEG C for 60-90 minutes at step 1; adding the ethanol amine in the foregoing parts by weight for reacting at 120-130 DEG C for 40-60 minutes at step 2; and adding the alkyl sulfonate in the foregoing parts by weight and carrying out uniform stirring to obtain the efficient collecting agent for ilmenite at step 3. The efficient collecting agent for ilmenite provided in the present invention is suitable for flotation of low-grade ilmenite and can lead to relatively high grade and relatively high recovery of ilmenite concentrate. In addition, the collecting agent is strong in collecting capability, good in selectivity, low in cost and environment-friendly, and has good market promotion value.

Description

technical field [0001] The invention relates to an ilmenite high-efficiency collector and a preparation method thereof, and belongs to the field of beneficiation agents for mineral processing. Background technique [0002] my country's titanium resources are relatively rich and widely distributed in nature, but the main ones with industrial value are ilmenite and rutile. There are more than 20 provinces and cities in the country where titanium ore is distributed, especially in the Panxi area of ​​Sichuan and the Chengde area of ​​Hebei. my country's titanium resources mainly present the following characteristics: more ilmenite, less rutile; more primary ore, less secondary ore; more lean ore, less rich ore, which increases the difficulty of comprehensive utilization of titanium ore. Therefore, based on the current situation, strengthening the efficient development and utilization of resources is an inevitable choice to change the advantages of my country's titanium resource...

AI Technical Summary

Problems solved by technology

Commonly used collectors for ilmenite flotation mainly include oleic acid, oxidized paraffin wax soap, hydroxamic acid, styrene phosphonic acid, styrene arsine acid, and combined collectors MOS and MOH series collectors. Some agents have achieved relatively ideal indicators, but there are still shortcomings, such as fatty acid collectors have disadvantages such as poor selectivity, high toxicity of styrene arsine acid, and high price of styrene phosphonic acid.

The most widely used in industry are mainly short carbon chain hydroxamic acids such as benzohydroxamic acid, salicylic hydroxamic acid, 5,9-hydroxamic acid and octyl hydroxamic acid. Although they have a good advantage in selectivity, but Its harvesting ability is slightly weaker, so its application is limited
