Project Introduction

In view of the impact of CNFREE gold environmental leaching reagent dosage, leaching time, particle size and type of minerals on gold leaching effect, and comparison of CNFREE gold environmental leaching reagent and conventional sodium cyanide, leaching test of CNFREE reagent was carried out in this project. The results are as following.

Gold Leaching Process

The test results show that CNFREE gold environmental leaching reagent has better gold leaching rate than conventional sodium cyanide under certain conditions, which can reach by more than 96%. Moreover, CNFREE gold environmental leaching reagent is low in toxicity but higher in economic benefits than conventional cyanide chemicals. It is also equipped with strong advantages in the process of purchasing, transporting, storing and usage. And the subsequent tail liquid treatment is relatively simpler than that of cyanide tail liquid. All these make CNFREE reagent leaching process completely comparable to the sodium cyanide process.
