Calcium concentrate leaching with H2SO4 aqueous solution is a two-phase countercurrent leaching process in which 80 of the concentrate with a concentration of 5-15 g/l is 60-100 micron lower. The leachate solution is leached from acid containing CI. 40-70g/L of ions and 20-90g/L of concentrated sulfur dioxide and leached solution form.
