Mini Pilot Plant Equipment

The Mini Pilot Plant puts the capability of a conventional full scale pilot plant in your hands, for a fraction of the cost. More than 30 MPP's in operation worldwide.

Eriez Flotation Division offers a more economical method of conducting metallurgical feasibility studies with the Mini Pilot Plant. Large-scale pilot testing is a multi-million dollar investment and can consume hundreds of tons of ore. These large tests are time consuming, expensive, and may require permitting just to obtain the required sample. By comparison, EFD’s Mini Pilot Plant runs at a feed rate of only 5 kg/hr using just drill core. This proprietary system simulates plant circuitry and allows various circuits, grind size, and reagent chemistry to be evaluated in a short time period. The Mini Pilot Plant can drastically reduce the expense and time necessary for development and confirmation of a plant flow sheet.

Proven repeatable results allow you to design and test flotation circuits with confidence. Extract the maximum amount of metallurgical information from as little as 150 kg of ore sample.

Save Time - Accurately determine mineral processing grade and recovery outcomes much quicker and earlier in the deposit evaluation process

and Money - Low sample acquisition costs, low sample disposal costs, low operating costs, low processing costs

While testing the entire ore property - You already have drill core from the ore zone, use it to confidently evaluate the economic potential of the entire ore body, not just one deposit.

 

With the MPP and using drill core samples a process metallurgist can:
