sulfuric acid solution that contains a corrosion inhibitor. an investigation was undertaken in order to study the parameters affecting sodalite scale dissolution by sulfuric acid: temperature, solution concentration, flow rate, etc. a custom-made set-up was used, simulating a heater cleaning operation, using scaled tube sections as test specimens.
this finding suggests that the dissolution of metals is incomplete when sulfuric acid is used to leach these samples. the iron leaching ratio increases slightly with increasing leaching temperature, while the change curves of lithium, aluminum and magnesium do not obviously change with increasing leaching temperature.

boiled with sulfuric acid with a concentration of 5 7 wt% for 60 min, alumina was extracted to 80 %. leaching with sulfuric acid was carried out at 90oc and reached an acid concentration of 10 20 %13. another patent reported 30 wt% as the recommended acid concentration14.
for the dissolution of low-grade bauxite ore, hulbert and huff used mineral acid and the results indicated that the rate of calcined bauxite dissolution was fastest with hydrochloric acid, slower with sulfuric acid, and slowest with nitric acid. in the case of sulfuric acid, the results also showed that the rate-controlling step was the diffusion of hydronium ions to the phase boundary.
