Abstract

The invention provides an ilmenite efficient flotation separation combined collecting agent and a preparation method and application thereof, and belongs to the technical field of mineral separation. The collecting agent comprises the following components in parts by weight: 40-50 parts of saponified fatty acid, 10-15 parts of naphthenic soap, 10-20 parts of hydroximic acid, 10-15 parts of primary amine, 2-10 parts of glacial acetic acid, 1-5 parts of sodium hydroxide and 1-5 parts of sulfuric acid. The collecting agent greatly saves the cost of mineral separation and purification, has the advantages of good collecting performance, good selectivity and high-efficiency separation, has a good flotation separation effect on ilmenite, and can perform high-efficiency flotation separation on low-grade raw ore, and the obtained ilmenite concentrate is high in grade and high in recovery rate.

Description

technical field [0001] The invention belongs to the field of mineral processing technology, and in particular relates to a combined collector for ilmenite high-efficiency flotation separation and its preparation method and application. Background technique [0002] Titanium is a very important strategic metal in the 21st century and has a wide range of applications in aerospace, shipbuilding, medical equipment and catalysis. Ilmenite is an oxide mineral of iron and titanium, and is the main ore for extracting titanium. There are more than 20 provinces and cities in China where titanium ore is distributed, especially in the Panxi area of ​​Sichuan and the Chengde area of ​​Hebei. The Panxi area is the largest production base of titanium concentrate in my country. According to the nature of the deposit, it is divided into gabbro type and peridotite type ilmenite. Gabbro-type ilmenite is usually recovered through the process of "slag separation → iron removal in the first sta...
