concentrations. pH of the leach solution was measured in each run. The necessary mixing was provided by gas evolving from the dolomite particles reacting with the acid. Filtration was made after each dissolution experiment to remove the undissolved residue and calculate the weight loss. Iron, aluminum and other ionic species were in trace amounts.

The process consists of ultrafine grinding of ore or concentrate followed by oxidative leaching at atmospheric pressure in agitated tanks. The leach residue is then processed via conventional CIP. The key control parameters are the particle size of the leached solids, the temperature and acidity of the leach and the oxidation potential.
