Leaching efficiency of sulfuric acid on selective lithium

Jan 01, 2020· As shown in Fig. 4, the leaching of metals increases with increasing sulfuric acid concentration. The leaching rate of lithium reaches 86.23% when the sulfuric acid concentration is 25%. Aluminum, iron and magnesium have similar leaching trendlines with lithium, and their leaching rates are lower than lithium.

Sulfuric acid injection in copper heap leaching LEWA

The leaching reagent (dilute sulfuric acid) is sprayed through sprinklers on top of the heap pile and allowed to trickle down through the heap, where it dissolves the copper from the ore. The resulting solution of sulfuric acid and copper sulfate is collected in a small pool. Copper concentration is around 65%. Next step is solvent extraction.

Uranium processing Leaching Britannica

Uranium processing Uranium processing Leaching: Roasted uranium ores are leached of their uranium values by both acidic and alkaline aqueous solutions. For the successful operation of all leaching systems, uranium must either be initially present in the more stable hexavalent state or be oxidized to that state in the leaching process. Acid leaching is commonly performed by agitating an
