THE LEACHING OF NEZAMABAD SCHEELITE WITH SULFURIC ACID

A new process for recovering scheelite ores comprises producing a concentrate from the ore, then leaching the concentrate with H_۲SO_۴ in the presence of H_۳PO_۴ and Na Cl at atmosphericpressure are discussed. Finely purification of the product will be described. The amounts of dissolution of tungsten in acid depend on the parameters such as time, temperature, type and concentration of acid and stilt as well as solid-liquid reaction. These factors were optimized for the result and described in details.
