The concentration is usually 0.01-0.05 % cyanide, or 100-500ppm. It should also be noted that the alkalinity of this solution must be high enough such that hydrogen cyanide is not produced, which is a very toxic gas. This is more important when sulfide minerals are in the ore, because they will oxidize, consuming oxygen and generating ,acid,.
