Iron Removal from Kaolins by Bacterial Leaching
Weathering of rocks generated large volumes of kaolin clays, quartz sands and micas, as well as other minerals, especially iron and titanium oxides. Kaolin is an economically important raw material often used in wide variety of ceramic applications, from high quality tableware and sanitaryware to electrical porcelain, tiles and glasses. There are some less common uses including glass fibre, whi...
متن کاملModofication of the Sarcheshmeh copper complex flotation circuit in response to a reduction in feed grade
The new copper processing plant of the Sarcheshmeh copper complex consists of two parallel circuits. After a primary crushing, the ore is sent to a SAG mill, and the product is further ground in a ball mill. The overflow of the hydrocyclones is fed to a flotation circuit that contains 8 rougher tank cells (RCS130), 3 cleaner cells (RCS50), 5 scavenger cells (RCS50), and a flotation column (as r...
متن کاملComparison of various extractants for recovery of Copper from Sarcheshmeh Chalcopyrite concentrate Ammonia/Ammonium Carbonate Leaching
Solvent extraction of copper from the copper leach solution obtained from the ammoniacal carbonate leaching of the Sarcheshmeh copper concentrate was carried out, and the performance of CP-150, LIX984N, and Kelex100 as well as the effects of different parameters involved were investigated. According to the results obtained, the extraction kinetics of all the three extractants was fast. High con...
متن کاملPhytoextraction-based process of metal absorption from soil in mining areas (tailing dams) by Medicago sativa L. (Alfalfa) (Case study: Sarcheshmeh porphyry copper mine, SE of Iran)
The present work was planned to evaluate the phytoextraction of metal mine tailings, Sarcheshmeh copper mine, SE of Iran, by the endemic plant species Medicago sativa L. (Alfalfa). In this pot experiment, we investigated the effects of seven amendments on the growth of alfalfa and uptaking metals from the mine tailings and stream sediment of tailing dam surface. The mean metal concentrations in...
متن کاملRemoval of Acetic Acid from a UREX+ Raffinate Stream
In the UREX+ process, acetohydroxamic acid is added to the UREX step to suppress plutonium extraction. Hydrolysis of acetohydroxamic acid (AHA) produces acetic acid and hydroxyl ammonium nitrate (HAN). The capability to remove acetic acid from aqueous process solutions is desirable as UREX+ flowsheets continue to evolve. Reasons for acetic acid removal include enabling recycle of the nitric aci...
