Ore Leaching Processes and Solutions

Ore leaching process and solutions: OrePartner realizes efficient metal extraction and green recovery with advanced leaching technology

As the core technology of modern hydrometallurgy, leaching process has unique advantages in processing low-grade ores, complex symbiotic ores and difficult-to-select ores. How to choose the optimal leaching process according to the ore characteristics to achieve efficient extraction of metals, cost control and environmental friendliness are the key technical challenges in the comprehensive utilization of resources.

OrePartner, with its profound accumulation and innovative ability in leaching technology, provides full-process solutions from leaching process selection, pharmaceutical development, equipment design, automation control to environmental protection treatment, helping customers to optimize metal recovery and maximize economic benefits.

I. Core challenges in leaching process selection

• Ore suitability: mineral composition, embedding characteristics, symbiotic relationship affects the leaching effect.

• Reagent consumption: reagent costs account for a high proportion of operating costs and need to be optimized and controlled.

• Reaction efficiency: slow leaching rate, long cycle time, affecting production efficiency

• Pressure on environmental protection: wastewater and waste residue contain hazardous components, and the treatment requirements are strict.

• Equipment corrosion: leaching medium is highly corrosive, equipment life and maintenance costs are high.
