1 <br />A 5 C 1 <br />' 6. DATA EVALUATION: CYTOX PROCESS <br />' The Cytox process is designed to reduce the free cyanide levels in the tailings prior <br />to discharge to the tailings facility. Cytox, a zinc/iron sulphate, reacts with the free <br />cyanide to produce non-reactive, metallo cyanide complexes. <br />' Pre-detox (pre-Cytox) levels of free cyanide from sample M1 are between 184 and <br />188 mg/L. Post-detox levels of free cyanide are calculated to be a theoretical <br />maximum of 32 mg/L in the lower pond/collection pond and more realistically a <br />maximum value in the range of 15 mg/L to 22 mg/L. <br />' Accordingly, the Cytox addition is apparently successful in reducing the free cyanide <br />to 8% to 17% of the level in the original tailings slurry. <br />1 <br />1 <br />1 <br />1 <br />1 <br /> <br /> <br /> <br /> <br /> <br /> <br /> 10 <br /> <br />
