How it work

Step by step working process

Gold mining is a multi-step process that involves extracting gold from the Earth and refining it into a usable form. There are several methods depending on the type of deposit (e.g., placer vs. hard rock), but here’s a general overview of how it works

Exploration of coltan

Before mining starts, geologists identify areas likely to contain coltan and gold using - Geological surveys, Satellite imaging, Soil sampling, Drilling and core sampling etc

Ore Processing

Once the ore is extracted, the gold must be separated from the rock - Crushing and Grinding, Gravity Separation, Flotation, Cyanidation (CIL/CIP), etc

Shipping and documentation

With the assistance of our professional out sourced partners, we ensure that the process of transporting gold is smooth and secure.

Waste Management & Reclamation
