Leaching of minerals using sulfuric acid

Sulfuric acid is considered a very strong and cheap acid. Most of it is used to break down minerals. This means the conversion of the generally very poorly soluble minerals into a substance from which the element or the desired compound can be more easily isolated. Extraction of raw titanium Titanium ores are primarily the… Continue reading Leaching of minerals using sulfuric acid

Uranium processing

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 ore ...

Leaching of minerals using sulfuric acid

There are various leaching methods, of which we are only interested in the wet chemical process. With concentrated sulfuric acid, iron (II) and titanium sulfates are formed. The oxidation of Fe(II) to Fe(III) is prevented by adding scrap iron since otherwise iron (III) hydroxide is formed, which contaminates the highly color-sensitive titanium hydroxide precipitate.

High Pressure Acid Leach

High Pressure Acid Leach (HPAL) is a process used to extract nickel and cobalt from laterite ore bodies. The HPAL process utilizes elevated temperatures (roughly 255 degrees Celsius), elevated pressures (roughly 50 bar or 725 psi), and sulfuric acid to separate nickel and cobalt from the laterite ore. HPAL has been used since 1961 when it was ...
