抄録

The extraction of Rhenium from some flue dusts containing 0.07-0.42% Re was studied. The processes tested were as follows:<BR>a) Direct leaching with water<BR>b) Leaching with aqueous solution containing oxidizing agents such as nitric acid, bromine or calcium hypochlorite.<BR>c) Sintering with Ca (OH) 2followed by leaching with water<BR>d) Leaching with alkali solution such as NaOH or Ca (OH) 2<BR>The best result was obtained when the samples were subgected to leaching with aqueous solution containing nitric acid or bromine. More than 95 per cent. of rhenium present was extracted.
