I work in the gold mine mill were we extract gold and silver from both oxide, sulphate and transitional ore at mill rate of 680 t/h, just now we introduce NaSH replacing copper at flotation other reagent in place froth, promoter, PAX.

What will be the best recommended dosing rate for the NaSH for such density at 27 to 29%

I suppose you are trying to sulphidize the copper for flotation. OK, this depends. You need to test to know. It could be 500 to 2000 g/t NaHS. Try and you will see how sulphidizing the oxide minerals with NaHS helps or not and at which concentration. Be sure to measure/monitor your ORP and operate under -75 mV.
