Description

The final yandying, always done by women, consists in holding the yandy full of wash on a slight slope and by a peculiar combination of jerk and slight rotation,the heavy tin ore is worked up hill to the right hand and the light quartz and felspar gravel worked downhill and over the left end of the yandy. A heavy garnet (spessarlite) which tends to remain with the tin is removed by taking advantage of the fact that the garnet crystals are almost spherical and once having started to roll under the influence of a rapid rotary motion of the yandy, they easily run off down hill to the left.
