Uranium ore physical beneficiation

Uranium ore before hydrometallurgical processing , firstly needs physical beneficiation, three of its role:

1, Enhance hydrometallurgy to mine uranium grade, abandoned part of the tailings. In physical beneficiation of uranium ore, radioactive selected for a success.The principles of radioactive selection process usually choose two points:

a.the first stage the mined ore is transported by the mine car or truck to the radioactive checkpoints , rich ores sent to bottled water smelting plants, waste rock used as fill material.

b.the second stage

radioactive checkpoint elected a new ore shipped to radioactive sorting plant by crushing, screening and washing, to enter the radioactive chosen machine, and it is divided into the concentrate and waste tailings.

Radioactive chosen machine can handle particle size range of 20 ~ 160mm. In order to improve the hydrometallurgy for the ore grade, the individual plant choose other physical beneficiation methods: heavy media beneficiation, abandoned part of the tailings; fine lean ore or radioactive chosen the poor in the mine, after crushing, use flotation enrichment ; magnetic uranium minerals, the available magnetic separation enrichment. Due to the leaching of tailings pollution of the environment, some countries are stepping up research to produce a more "clean" tailings and waste emissions from uranium process. First sulfide mineral flotation and a strong magnetic field magnetic Canada Elliot Lake uranium ore, not only to improve the grade of uranium and the recovery of the radium and pyrite (the former is the source of the radioactivity of the tailings, which is in the bacterial under the action of radioactive pollution from acid).

2, grouped on the ore, and hydrometallurgical processing separately. Some uranium ore contains carbonates, sulfides, and other components. If direct acid leaching or alkaline leaching, high reagent consumption, and the leaching of uranium is low.Grouping ore by flotation and separately hydrometallurgical processing, can significantly reduce reagent consumption, improve uranium leaching rate.

3, recovery of useful components. Comprehensive recovery of uranium, gold in symbiotic gold uranium quartz pebble conglomerate ore and pyrite recovery order is: first gold then uranium or first uranium then the gold, the last flotation of pyrite; first flotation of pyrite mine, and then from the flotation concentrate, tailings, respectively uranium gold extraction.
