Using conventional approach of leaching to extract gold from Calaverite or Gold-Telluride (2 replies and 3 comments)

I am looking for Hydrometallurgical options to extract gold from Calaverite or Gold-Telluride using conventional leaching techniques instead of sending concentrates (esp. of froth flotation) to further pyrometallurgical pretreatment prior to leaching. Thank you.

The process of heap leaching gold from gold ore is to crush low-grade gold ore to a certain size (or granulate) and pile it on a leak-proof bottom mat paved with materials such as asphalt, concrete or plastic, and use low-concentration cyanide, alkaline The solution, non-toxic solvent or dilute sulfuric acid and other solutions are sprayed on the mine pile to dissolve the gold, and the gold-containing solution is infiltrated from the mine pile, and then the gold is recovered by methods such as activated carbon adsorption or zinc powder replacement precipitation.

You can try this method

Thank you huahua. That actually confirms a respond I got from a consultation I had with a Senior Mineral Processor. He did mention one mining operation in my country employing heap leaching technique to some of their Au-Te ore along with others. I'll try and integrate some of its concepts into conventional leaching.

Gratitude with appreciations SmartDog. The link proves more than helpful, almost solved my problem. I will conduct leach tests basing on the options presented in the link, maybe altering leaching parameters here and there to see if it present favorable outcomes in terms of Au recovery.
