In general, the metal assay value of ball mill or flotator feed are taken as the basis of the crude are grade. Both assay values of the ball mill feed and the flotator feed are theoretically the same, but actually they are not the same.
To investigate this difference in sampling, the writers have studied the influence of are grain size On the assay value. As the lead and zinc has shown the different behaviour in the sampiing test, the writers have considered theliberation degree of the mineral grain as the most important factor in the sampling problem.
