grade hydrochloric acid HCl is supposed to remove the iron oxides. However HCl tends to flash dissolve the minerals it touches first without much penetration if not amended by other products. This leads to the condition where a good performance recovery fades quickly. HCl is also aggressive with
Apr 03 2019 Some Japanese companies advocate the use of phosphoric acid or hydrochloric acid type tank pickling. After the 1950s in China pipe pickling was usually acid-washed with mineral acid hydrochloric acid or sulfuric acid and then neutralized with lime water or sodium carbonate. After the 1980s various new processes were also adopted.

Each batch of loaded carbon was removed from the first column in series and washed with dilute hydrochloric acid to remove base metal impurities and inorganic fouling primarily in the form of calcium carbonate scale. The acid washed carbon was neutralized using dilute caustic solution before transferring to the strip vessel.
Oct 30 2013 There are several commercially established processes to produce synthetic rutile by leaching ilmenite with hydrochloric acid HCl which can be broadly classified into two categories those which use concentrated HCl above the azeotropic concentration of 21 ww HCl and those that use sub-azeoptropic HCl concentrations typically 17-20 ww HCl.
