Approximately 100 per cent of the total copper is soluble in one hour at 35° C. in sulphuric acid or in acidified ferric sulphate solutions when the size of mineral is minus 100 plus 200 mesh. In 1 or 2 per cent neutral ferric sulphate the dissolution is slower, but in nearly every instance the mineral is completely dissolved in 24 hours or less.
