|
Saskatchewan
|
|
treatment process.
|
|
Saskatchewan, Canada
|
-
|
Process
development and design for treatment of in-plant waste
|
|
|
|
solutions and residues.
|
|
|
-
|
Process
development and design of waste sludge handling
|
|
|
|
facilities.
|
|
|
-
|
Solidification
and immobilization testing of waste sludge and
|
|
|
|
residues.
|
|
|
-
|
Preparation
of representative uranium mill tailings for chemical
|
|
|
|
and physical characterization studies.
|
|
|
-
|
Testing of
paste tailings technology.
|
|
|
-
|
Detailed
engineering for paste tailings thickener installation.
|
|
|
-
|
Process
design and operation of a gold recovery plant to recover
|
|
|
|
gold
and residual uranium values from high-activity radioactive
|
|
|
|
uranium tailings.
|
|
|
-
|
Development
of a process to recover metal values (nickel and
|
|
|
|
cobalt)
from uranium plant waste solutions and tailings to produce
|
|
|
|
a marketable product.

|
|
|
National
Uranium Tailings
|
-
|
Capital
and operating cost estimates of three different uranium
|
|
Program
(NUTP)
|
|
waste
management practices in use at operating Canadian
|
|
Canada
|
|
uranium mines.
|
|
|
-
|
Preparation
of the technology research component of uranium
|
|
|
|
disposal
practices for the National Uranium Tailings Program to
|
|
|
|
summarize
existing practices and to identify areas of research for
|
|
|
|
funding.
|
|
|
-
|
Evaluation
of the geochemistry of thorium in uranium mill tailings.
|
|
|
-
|
Chemical Study
of the State of Nickel and Arsenic in
|
|
|
|
Saskatchewan Uranium Mill
Tailings.
|
|
|
-
|
Study
on the geochemical behavior of non-radionuclide
|
|
|
|
contaminants in uranium mill tailings.
|
|
|
-
|
Assessment
of natural barriers for uranium mine tailings.
|
|
|
-
|
Development
and design of a process to remove radium from
|
|
|
|
uranium
mining effluents by a radium-selective ion exchange
|
|
|
|
complexer. This work led to a full-scale
installation of a
|
|
|
|
contaminated
water treatment facility at the Key Lake uranium
|
|
|
|
mine in Saskatchewan.
|
|
|
-
|
Preparation
of the process and waste treatment component of
|
|
|
|
the Canadian Uranium Mill Waste Disposal Technology Manual.
|
|
|
|
This
manual has been used extensively in the uranium industry as
|
|
|
|
an
excellent reference document for uranium tailings disposal and
|
|
|
|
decommissioning.

On-Site
Experience
|
-
|
Experience
and expertise related to waste management has been
|
|
|
|
gained
on all the uranium mines located in northern
|
|
|
|
Saskatchewan including the Cluff Lake Mine, the Key Lake Mine,
|
|
|
|
the
Rabbit Lake Mine, the Cigar Lake Mine Project, the McClean
|
|
|
|
Lake Mine, the Midwest Project, the McArthurRiver Mine, and the
|
|
|
|
Dawn
Lake Project.
