Mines extracts having negatives impacts on the natural environment. In the face of significant global issues, such as climate change, we as mining operators engage into sustainable development as a solution to mitigate negative externalities.
Gold production in Latin american comes mainly from artisanal miners who suffer from low recovery rates, cause environmental damages and have compliance issues. Colombia gold structured a modern ore processing mill project in bolivar Colombia, with the aim of providing a solution to these issues.
Gold Colombia owns three mining concessions and has memorandum of understanding to acquire several more potential concessions with high grade gold. To secure gold ore supply, Gold Colombia invited local legal artisanal miners to join the project.

Colombia Mill Project & Mill Production Process
- Ore arrives at the plant
- Ore is fed into a series of crushers and grinding mills. To obtain a final grind of 70% passing 200 mesh
- Water is added to create slurry with target 44% solids
- Slurry send to carbon-in-leach system cyanide dissolves gold
- Solution goes into activated carbon tanks gold attaches to the carbon and is pulled from the solution
- Process get gold off carbon merrill-crowe circuit uses zinc dust to precipitate the gold adsorption-desorption-recovery. Plant that uses steel wood and an electrolytic cell
- Gold is smelted at over 1000 grade of. Higher specific gravity of gold sends it to the bottom of the crucible
- Liquid gold is poured into molds gold and silver in dore form are sold to refineries
