Assessment of Present
Phosphate Mining and Beneficiation Practice and the Evaluation
of Alternative Technology

Facilitating the generation and exchange of information that
can help improve the phosphate industry's efficiency is one
of FIPR's key roles. Increased efficiency typically means
lower costs and fewer negative impacts on the environment.
At a time when phosphate companies were cutting back on their
research programs and national programs like the U.S. Bureau
of Mines were being eliminated, this study generated useful
information for researchers and engineers grappling with efficiency
questions. It provided data, costs, and process technology
and pointed out future direction for technology improvements.

Development of
an On-line Concentration Sensor for Slurry Flow Through Large
Diameter Pipes

Over 100 million tons of phosphate matrix are transported
from mining pits to beneficiation plants in Florida every
year. The energy cost for long-distance pumping of such huge
amounts of slurry is extremely high. The industry is constantly
searching for ways to increase slurry density and reduce the
amount of water to be pumped. A reliable density analyzer
provides an operator with the information needed to slurry
matrix at a solids concentration the pump design can handle
and prevent catastrophic plugging of the pipelines. This sensor
proved to be reliable and also eliminated health concerns
connected to the radiation meters the industry currently uses.
