Somalia Oxide Gold Ore: Reviewing a 200 TPD Leaching Plant

Dasen Mining reviewed an oxide gold ore sample from Somalia with a reported gold grade of 1.8–3 g/t. The customer initially asked about a small containerized gold leaching plant. After discussing the required capacity with our engineer, the customer chose to focus on a 200 TPD gold leaching plant option.

The discussion covered two separate questions: which process to evaluate for the ore, and what capacity the plant would need.

Why the Discussion Moved to 200 TPD

The smaller containerized unit initially discussed did not match the customer’s intended throughput. The conversation therefore moved to a 200 TPD option.

This was a decision about the particular unit being considered—not a conclusion that all containerized plants are too small. “Containerized” describes how equipment is arranged, while “200 TPD” describes daily processing capacity.

CIL or CIP: What Needs to Be Confirmed?

In the gold CIL process, leaching and adsorption onto activated carbon take place together. In the gold CIP process, carbon adsorption follows the main leaching stage.

For this ore, the choice should be supported by test results, including gold recovery, leaching time and reagent consumption. These results are needed to move from an initial discussion to a plant design.

Our gold CIP/CIL processing plant options provide an overview of the equipment and process stages.
