Technical field
The present invention relates to ore floatation collecting technical field, specifically a kind of low temperature resistant multiple Barbiturates Rare Earth Mine flotation is caught
Receive agent and its preparation method and application.
Background technique
It is 18,590,000 tons that rare earth oxide commercial reserves has been verified in China, accounts for about the world and has verified rare earth reserves
23.6%, rare earth resources deposit type is complete, is distributed wide and Relatively centralized, at present in the province in 2/3rds or more the whole nations
(area) is it has been found that thousands of place mineral deposits, mine point and the mineralising place of production, and integrated distribution is in the Bayan Obo in the Inner Mongol, Southern Jiangxi, wide
The ground such as eastern North Guangdong, Sichuan Liangshan District and Shandong Weishan, form the Distribution Pattern in north, south, west, east, and have the distribution of northern light south heavy
Feature.There are many type of rare-earth industry mineral, and the most important three kinds of mineral of industrial abstract rare earth metal are bastnaesite at this stage
[RECO3F], monazite [(RE, Th, Y) PO4] and xenotime [(Y, RE) PO4].Rare earth metal be widely used in clean energy resource,
The fields such as science and techniques of defence, industrial technology, electronic product.
Alkylhydroxamic acid is mostly used greatly, with the different of phenyl ring with the Rare-earth Mine that bastnaesite is main rare-earth mineral at present
The mixing of one or more of hydroximic acid, naphthenic base hydroxamic acid, naphthalene hydroxamic acid is used as collecting agent, although such collecting agent
Achieve better index in bastnaesite type rare earth flotation, but its that there are prices is high, dosage is big, resultant effect is used alone not
Ideal, difficult with the agent degradation of phenyl ring and naphthalene nucleus, tailing water is difficult to the disadvantages of meeting the requirement of environmental protection；Meanwhile
Silicic acid phosphoric acid salt Rare Earth Mine can not effectively be sorted.
Currently, the research and development and application for silicic acid phosphoric acid salt Rare Earth Mine collecting agent are detected in Chinese patent literature
CN201711202681.X, the applying date 20171127, title are as follows: a kind of phosphosilicate type Rare Earth Mine flotation collector and its preparation
