About QPEC
Specialists in Solvent Extraction for Over 45 Years
At Quinn Process Equipment Company, we have over 45 years of expertise in designing and manufacturing process equipment for pilot and small commercial plants in the minerals industry.
What Sets Us Apart
QPEC mixer-settlers feature specially designed impellers that mix and pump feed streams at the mixer eye, eliminating the need for interstage pumps and simplifying system control. Only external feed pumps and associated components are needed.
Available in various configurations and materials, these units maintain equal liquid levels in both mixer and settler for easy startup and shutdown without surge tanks.
We apply the same advanced technologies and processes to both mineral extraction from mining and material recovery through recycling, ensuring sustainable practices and maximum resource efficiency across both operations.
Design Philosophy
Every system is tailored to the unique needs of your project, with a range of sizes and materials to suit various applications.
Proven Track Record
Each installation started up quickly, without complications or failures, and performed reliably to the client's full satisfaction.
Full Integration
Pilot plant units include all interstage piping and recycle provisions, mounted on a common structural steel frame with explosion-proof motors and VFD controls.
