Objective

The main objective of the Micro Ecros project is to solve the following  challenges:

  • Recovery of metals in the flotation circuit is affected by sulphide species that interact with the reagents and are in consequence carried up to the froth unintendedly;
  • Pyrite is one of the most common gangue sulphides present in mineral ores: c.a. 70%;
  • Successful processing of complex sulphides is key to face the coming years of extractive technology;
  • Pyrite accompanies flotation reducing processing efficiency unless successfully depressed.

The solution (technology)

The Project Output:

  • A process and equipment that enables the selective separation of Pyrite before it reaches the flotation circuit;
  • Lower cost in the flotation circuit – less reagent consumption, less air inlet and less energy consumption;
  • Higher successful use of specific contact surface Bubble/Particle thus reducing the flotation costs and efficiency.

The Solution will:

  • Separate pyrite before it reaches the flotation circuit and therefore will enable a cleaner mineral entering for flotation, boosting the recovery efficiency of flotation.
