Been looking into why floatation isn't going well. So wanted to check on the ranges of the accepted Froude number for the floatation cells.

What are the conditions(agitator speed, air supply, dosage of senkol preferred pH etc.) used when using Senkol in floatation.

Hallo, all. How I can prognos grade tails if grade ore will be changed? For example: Ore: 1 gpt, 100tph; Concentrate: 20 gpt, 4 tph; Tails 0,21 gpt, 96 tph. What I get if ore will be 1,5 gpt, or 0,8 gpt? circuit not change.

While flotation is posible, since most of the metals in the catalyst are nano partilces the efficiency will not be very good. Leaching would be simpler and more efficient.

Hi, I am setting up a intrinsically safe zone for our PAX mixing and was going to put a spill kit in the area. I was told by a metallurgist that a Hydrocarbon Spill kit would do as opposed to a chemical spill kit. Is this plausible?
