Testing Minerals for Jig Recoverability. The fact that treating a mixture of minerals under jigging conditions increased the amount of mineral saved; or, as Professor Richards aptly terms it, " the extra jig-catch," has long been known. To account for this fact a number of theories have been proposed.
