EXECUTIVE PROFILE
Consistently ahead of the times in envisioning and providing innovative applications of existing
technology. Proven expertise in conceiving and applying process control instrumentation and
systems to the mineral processing industry.
CAREER ACHIEVEMENTS
Engineering and Management
Generated worldwide annual revenues of approximately $20 Million through:
• Developing the first microprocessor-based conveyor scale integrator. This
established the company as the conveyor scale leader and nearly five years elapsed
before another digital integrator appeared.
• Developing the precision conveyor scale including microprocessor electronics into
a unit accepted by weights and measures officials worldwide.
• Developing a low cost microprocessor integrator for moderate accuracy in-plant
weighing.
• Conceived and specified the control strategies and process control equipment for a major
taconite processing plant. Successfully convinced the company to utilize a central
control room, the first in the taconite industry. Supervised development of the software
for the computers, including a proprietary operating system which incorporated features
not commercially available at that time.
• Successfully completed a peak power study of a mineral processing plant resulting in an
annual power cost savings of between $100,000 and $300,000.
• Developed proprietary specialty instrumentation for a manufacturer of mineral processing
equipment to enhance process performance.
• Conceived and developed a density compensated level control system for flotation cells to
improve metallurgical performance.
• Completed a consulting project for a major taconite company which reduced iron losses
by more than 50 percent.
Acquisition
• Member of a five person team which evaluated a $120 million group of companies for
acquisition. Reviewed their technologies, products, and technical personnel. Reported
strengths and weaknesses to the acquisition team and served as vice president-technology
in the resulting company.
• Evaluated the technology of a discrete in-motion weighing product line for acquisition.
This product line, including checkweighers, sorters, and metal detectors currently has
annual revenues in excess of $20 million.
• Evaluated product technology and personnel of a sister company's bulk material sampling
system and recommended acquisition. Sampling became a profitable operation.
CAREER EXPERIENCE
CHASE TECHNOLOGY, INC Crosby, MN 1993-present
President
Provide consulting services to mineral processing operations, instrumentation
manufacturers, and users of dynamic weighing systems. Consulting with NIST (National
Institute of Standards and Technology) to improve belt-conveyor scale weighing
accuracy. Consulting with USSteel Corp. for reduction of iron losses and improved
efficiency in a taconite processing plant.
ENVIROTECH, a Baker Hughes Co Houston, TX 1992-1993
Senior Scientist
Intercompany consultant to the Envirotech companies. Consulted in mineral processing
instrumentation, microwave level sensing, in-motion weighing, and other products and
applications. Developed an improved gas chromatograph detector which was smaller and
required less frequent cleaning than previous versions. Developed a unique control
system to allow broader application of an existing pump series.
BAKER HUGHES INSTRUMENTATION GROUP Minneapolis, MN 1990-1992
Vice President-Technology
The group was formed from Ramsey Engineering and its subsidiary TN Technologies
with the addition of several companies acquired from Tracor. Initiated uniform reporting
of product development projects to better track costs and results. Initiated and chaired
meetings to share technical information of inter-company importance. Advised group
president of problems and successes in technical development.
RAMSEY ENGINEERING CO 1970-1990
Vice President-Technology 1977-1990Conceived and developed improved electronics for in-motion weighing and process
control. Coordinated product development at a subsidiary, TN Technologies, including
non-contact density and level instrumentation and elemental analyzers based on X-ray
fluorescence. Two of the analyzers each won IR100 awards for innovation.
Manager of R&D 1974-1977Selected and hired engineers and technicians to build a product development group.
Produced a new family of conveyor scales for Ramsey using strain gage load cells for
improved accuracy. Developed the first digital conveyor scale using a mini-computer to
acquire and process the weighing information from two scales in a ship loading
application.

ADDENDUM A
P W Chase experience directly related to magnetite processing. The deposit that this plant
processes is magnetite taconite at about 20% MagFe.and the concentrate is about 5% Silica and
about 85% smaller than 53 microns.
PROCESS PLANT DESIGN
Developed process control strategies for a magnetite crusher and concentrator.
Specified instrumentation for process control of the plant
Specified computer system for data acquisition from plant operation
Supervised software development for the computer system
Supervised contractor installation of process instrumentation
PLANT OPERATION
Became Works Metallurgist for the operating plant with responsibilities as follows:
Metallurgical balance
Iron recovery, crude to concentrate
Concentrate chemistry and size consist
CONSULTING–MAGNETITE PROCESSING
Returned to the plant after several years and performed metallurgical and instrumentation
consulting for several years.
Power study. Power demand of pit and plant. Recommendations provided annual
savings of $100,000 to $300,000.
Iron recovery. Reduced iron losses to tailings by more than 50 percent through improved
process control and instrumentation.
Water balance This is a cold climate plant and return water from the pellet plant can
increase concentrator water temperature and therefore process efficiency. Tailings
thickener control also conserves water temperature in winter as well as reducing pumping
costs of return water from the tailings basin..
Study of flotation performance for improvement of concentrate grade.
Participated in evaluation of high pressure roll crushing for this location.
ADDENDUM B
P W Chase experience directly related to beltweighers (belt-conveyor scales). Director of
Research to develop the first digital belt-conveyor scale electronics for Ramsey Technology. Has
provided technical assistance to National Institute of Standards and Technology (NIST) for
international development of Organisation Internationale de Metrologie Legale (OIML) R50 and
has participated for many years in the development of the belt-conveyor scale section of NIST
Handbook 44.
Paul Chase has provided consulting service for belt-conveyor scale installations including
participation in litigation. He has expertise both in the design of beltweighers and in their
application and calibration.
