摘要
Abstract
Monazite is a phosphate mineral that rarely has independent deposits and is usually associated with nonferrous metals such as zirconium,titanium,and tin,thus it can be recovered as a by-product while these nonferrous metals are mined.According to the investigation,China has an annual production capacity of about 50,000 tons of monazite concentrate.Monazite is rich in valuable elements such as uranium,thorium and rare earth,but it is mainly used as raw material for refining rare earth at present,and the resources of uranium and thorium are not well recycled.This paper analyzes the feasibility of the process of leaching monazite slag with low acidity and low temperature,and studies the economy of comprehensive utilization of monazite slag to recover valuable elements.The research shows that the process is feasible and has high economic value.关键词
