Hydrometallurgy/Titanium cladding leaching autoclave
One of the principal applications for which HXCHEM Pressure Reactors are used is in the field of hydrometallurgy or the extraction of metals from their ores by leaching with acids at elevated temperatures and pressures. The reactor is high resistant to high pressure, high temperature, strong acidity and long-term wearing. The reactor works in high temperate (approx.150℃-250℃) and high acidity environment and the working media is high concentration ore pulp.
Material of construction
These reactions are generally carried out using sulfuric acid as the leaching acid. Titanium is almost the universal metal chosen as the material of construction
for reactors used in this field. While Titanium has poor resistance to pure sulfuric or hydrochloric acid, the presence of the high-valence metal ions such as ferric,
cupric, nickel, etc., resulting from the extraction process dramatically reduces the corrosive effects of these acids on Titanium.
Raw Titanium will burn in the presence of high pressure oxygen. Essentially all hydrometallurgy extractions are done under a high pressure oxygen atmosphere to maintain the oxidative leaching conditions. So great care must be taken to avoid conditions where the Titanium can be ignited in the oxygen atmosphere. So hastelloy C276 oxygen tube will be commonly used in this place.
