Content Of Gold

The content of gold ore in Wa region of Myanmar is 3.52 g/t ~5.87g/t, and it contains 9.32% arsenic, it belongs to awkward gold ore with gold embeds in pyrite as fine granular. so the drawbacks of low leaching rate and wasting of resources existed in the early cyanide production. A technology of adjusting pH in lime water and further leaching after regrinding was confirmed by contrasting the mixing effect in different reagent. The experiment results showed that a leaching rate of 81.63% has been obtained by adopting the conditions which pulp density is 40%, the pH of pulp adjusted in lime water is 10, the total NaCN dosage of three additions is 3 and the material is reground before third addition.
