How Did Our Customized Pit Leaching Project in Chennai Deliver High Gold Recovery?

/in /by

Pit leaching is an effective gold extraction process for deposits where heap leaching is not feasible, especially for small- and medium-scale operations with high clay content. Our company recently completed a highly professional pit leaching project in Chennai, India. This project combined customized solutions, environmentally friendly chemicals, and continuous technical support, ensuring both efficiency and sustainability.

Project Background

The client in Chennai required a practical and efficient method to extract gold from fine-grained ore with clay content. Traditional pool leaching methods often result in poor permeability and low recovery rates. To overcome these challenges, we designed a customized pit leaching process supported by green extraction agents and on-site training.

Customized Solution and Technical Support

Our service extended beyond delivering equipment and chemicals:

  • Customized process design: Tailored to the ore characteristics, ensuring maximum leaching efficiency.
  • Remote follow-up guidance: Engineers provided online consultations during the construction and testing phase.
  • On-site training: After infrastructure completion, engineers traveled to Chennai to guide operations and train staff.
  • Supply of chemicals: We provided environmentally friendly gold extraction agents, improving recovery while reducing environmental risks.

Process Advantages of Pit Leaching

Pit leaching overcomes the limitations of traditional pool leaching. Key advantages include:

  • Improved permeability: Prevents ore hardening and ensures uniform solution distribution.
  • Higher recovery rate: Column tests achieved up to 94% diffusion rate compared to 60% with conventional methods.
  • Lower costs: Requires minimal additional equipment (small crushers or nozzles).
  • Economic benefits: Improved leaching rates reduce tailings grade by 0.2–0.5 g/t. Even a small pit leaching plant processing 50,000 tons per year can yield at least 10 kg of gold annually.
