Leaching Technology

OVERVIEW

The MET63 leaching designs are developed for mobile / modular processing modules and hydrometallurgical modules and suitable for the following applications:

  • Suitable for small scale operations i.e. < 50 tph
  • Engineered for both low grade and high grade applications

MET63 has experience in specialized leaching circuit design and can offer the following skid mounted designs as shown below:

  • Precipitation
  • Ion Exchange Systems
  • Crystallization Systems
  • Membrane Technology
  • Solid – Liquid Separation Separations
  • Specialized stainless steel plant

ADVANTAGES

  • Process Development (R&D)
  • Feasibility Studies
  • Detailed Design
  • Complete EPCM service

FUTURE LEACHING TECHNOLOGY OPPORTUNITIES

  • Acquisition of other low-grade/tailings projects
  • Toll treatment of gold, copper and nickel run-of-mine, or tailings
  • Potential to rescue marginal operations via bypassing the plant bottle neck
  • Increased total production throughput of current operations by treating lower-grade ore/stockpiles

TYPES OF PLANTS

SiMPLeR leaching technology

Mobile leaching solutions, combining leaching, solid-liquid separation, and washing.

  • Capable of leaching gold and base metals (ore dependent)
  • No milling required – fine crushing application (ore dependent)
  • Improved plant-water balance
  • Limited civil and earthworks required
  • Pre-manufactured and factory tested
  • Reduced commissioning time
  • Limited site installation time required (estimated 2-5 days per reactor)
  • Low capital requirements
  • Relocatable

FLeXoR – Fluidised Leach Oxidation Reactor

Enabling leaching technology to develop previously uneconomic mineral deposits/resources.

  • Capital requirements lower than conventional leaching technologies
  • Higher metal recoveries compared to heap-leach operations
  • Large operating window
  • Allows for a wider material size distribution (fine and coarse material – up to 2 mm) to be treated in the plant
  • Rapid construction compared to other leaching system

 

Product Background

  • Developed over a period of 10 years through extensive research and testing.
  • Laboratory test-work was conducted on DRC copper ores. The demonstration pilot plant was constructed and successfully operated.
  • Test work at University of Pretoria is ongoing on gold ores to generate a data base for current and future hydrometallurgical process plant design.
  • The existing data base held by MET63 has allowed for fast and efficient process solutions put forward to clients.
