Leaching an overview ScienceDirect Topics

This process of leaching is termed as high-pressure acid-leaching process or HPAL process, which is highly selective to nickel and cobalt. A pressure leaching autoclave is used in this process that receives the hot feed slurry through positive displacement slurry pump and maintains the slurry residence time between one and two hours.

A modified process for leaching of ilmenite and

2020-12-1 · Recently, the caustic process as a novel method for treating ilmenite has emerged. In this process, ilmenite reacts with potassium hydroxide at 220 °C to produce the decomposed ilmenite (DI) which contains potassium titanate (K 4 Ti 3 O 8) and ferric oxide (Fe 2 O 3) (Liu et al., 2006a; Shojaei et al., 2014). The DI can be leached in acidic solution followed by hydrolysis to produce titanium dioxide.
