Investigating Concentration Distributions Of Arsenic Gold

Gold content in the sample was comparatively far greater than arsenic and antimony this is indicative of level of gold mineralization in the concession where the sample ore was taken. The concentration of gold in the composite sample was in the range 564-8420ppm as compared to 14.33-186.92ppm for arsenic and 1.09-9.48ppm for antimony.
