چکیده
Weathered crust elution-deposited rare earth ores are key strategic resources and the main source of medium heavy earths. This paper summarizes development leaching technology ores, compares advantages disadvantages three generations technology, introduces improved heap new leaching–extraction integration enhanced leaching, focusing on weathered ores. In this paper, agents is expounded, research status trend composite ammonium salt agent, impurity inhibition swelling seepage-promotion agent also introduced. And mechanism direction agents. Moreover, future proposed, which green, efficient, safe utilization.

Preservative leaching from weathered CCA-treated wood.
Disposal of discarded chromated copper arsenate (CCA)-treated wood in landfills raises concerns with respect to leaching of preservative compounds. When unweathered CCA-treated wood is leached using the toxicity characteristic leaching procedure (TCLP), arsenic concentrations exceed the toxicity characteristic (TC) limit of 5mg/L in most cases. The majority of discarded CCA-treated wood, howeve...
متن کاملE ects of Reagent Concentration and Particle Size on Di usion Rate of Mixed Ores with Rare Elements
The leaching reaction kinetics of weathered crust elution-deposited rare earth with mixed ammonium salts was studied. The in uence of concentration of reagents and particle size of ore on leaching rate was investigated. The results showed that the di usion process and leaching rate could be improved by increasing reagents concentration and decreasing leaching owing rate and particle size. The l...
متن کاملMineralogy and uranium leaching of ores from Triassic Peribaltic sandstones
The recovery of uranium and other valuable metals from Polish Peribaltic sandstones were examined. The solid-liquid extraction is the first stage of the technology of uranium production and it is crucial for the next stages of processing. In the laboratory experiments uranium was leached with efficiencies 71-100 % by acidic lixiviants. Satisfactory results were obtained for the alkaline leachin...
متن کاملBacterial leaching of discarded copper ores from Yongping, China
The elementary and phase analysis of discarded copper ores from Yongping of China has been performed. The experiments of extracting copper from the discarded copper ores were done with the mixed bacteria obtained through a series of enrichment, separation, domestication and combination tests. The results show that in the process of bioleaching, the pH value rises at first and drops gradually. T...
متن کاملOptimization of Acid Leaching of Rare-Earth Elements from Mongolian Apatite-Based Ore
Optimization of the acid leaching process for Mongolian apatite-based ore containing rare-earth elements (REEs) was studied. The ore contained approximately 10% of REEs as total rare earth oxides, and the major impurities were Ca (33% as CaO) and Fe (23% as Fe2O3). Fe bearing minerals could be removed by passing the sample through a wet high-intensity magnetic separator before leaching. After m...
