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.

Simple answer you cannot predict with any reasonable degree of accuracy.  To be confident you need to do laboratory tests.

You can make a guess using the standard metallurgical balance equation.

Thank you.

As far as I know. If grade in feed increases, then increase value of recovery and grade in tailings.

In unofficial sources I saw formula where t2=t1*√f2/√f1. Unfortunately, I do not find official confirmation of this.
