Thunder Bay Terminals Ltd. Site selection to operation— the management function

Abstract Thunder Bay Terminals' plant, now in operation, cost about 70 million dollars and was completed on time and under budget. The paper is the project manager's account of this accomplishment. From site selection through feasibility, engineering and construction to realization, he emphasizes the necessary philosophies for the control of time and money. The computer as a tool is discussed, as well as techniques for procurement.
Keywords: Thunder Bay Terminals Ltd., Site selection, Management, Construction, Planning, Approvals, Permits, Scheduling.

Summary: The transportation challenge began with the need to move millions of tons of coal annually from Western Canada to Ontario. The paper will discuss the options which were available, the final mode selected and the economic trade-offs which were involved. It will outline the demands of unit train technology and the effect of transportation requirements on the other elements of the whole system.

Summary: Concern over the acid drainage and radionuclide dissolution problems associated with current uranium tailings disposal methods, as well as the lack of thorium production in Canada, has prompted investigation into new and improved methods for the extraction of uranium and thorium from their ores.One such method currently under investigation at CANMET is the high-temperature chlorination of uranium ore, for which the objective is to develop a process which is both economically viable and...

Summary: After more than 93% of the uranium is extracted from Elliot Lake uranium ores by a sulphuric acid leaching process, the leach residue (tailings) contains small amounts of uranium and radioactive isotopes, particularly radium-226, which is the most serious health hazard. Heavy metal components and pyrite are also present, along with the gangue minerals. Currently, over 1000 acres of the Elliot Lake area are covered with these tailings, which contain over five million tons of pyrite.Because of...

Summary: McKellar Island, the site of the Thunder Bay Terminals coal handling facility, is situated in a low-lying delta area. The ground surface across the island, which is relatively flat at between 1 and 5 ft above lake level, is underlain sequentially by surficial peat materials, extensive lacustrine strata and glacial till deposits which overlie shale bedrock. Each of these major stratigraphic units significantly influenced the design and construction of major features of the facility.Coal is to...

Summary: Orebodies of the Renison Bell - Mt. Bischoff tinfield in Tasmania are stratabound, conformable lenses of massive cassiterite-bearing pyrrhotite, with underlying discordant, fault-fracture-controlled and more siliceous ore. The deposits occur in eugeosynclinal, trough-deposited sedimentary and mafic volcanic rocks which are stratigraphically equivalent to differentiated volcanic rocks that contain volcanogenic massive base metal sulphide deposits in a parallel arc to the east. Textures of the...
