Extract the gold out of SLAG

[sompong]

We grind the factory slag got the slag head and melt and get the tail to cyanide solution
the problem is we can not dissolve all of gold to the cyanide solution and achieve only 70-80 %
So please advice

It might help to know how much slag you have, and how much value is contained within.

The values can be successfully recovered by furnace, but to be clear, they shouldn't be there in the first place. Had the proper flux been used, the values trapped in the slag would have been too low to be of concern.
