GRG test analyzing (No replies)

Hello guys,

I am doing a GRG test and analyzing the results according to the paper "Laboratory procedure to characterize gravity-recoverable gold" . I do not know the meaning of "Yield", "Calc.: 4.787 g/t" in Table 2 and how to calculate them. 

I guess "Calc.: 4.787 g/t" is calculated head grade, but why it differs from the head grade in stage 1 (4.92 g/t)?

Hope for your answer, many thanks!
