History and Development of Mount Wright

Abstract Incorporated in 1957 under the laws of the Province of Quebec, Quebec Cartier Mining Co. undertook the development of its low-grade iron ore reserves located at Lac Jeannine in the southwest extremity of the Quebec-Labrador trough. This challenge comprised the construction of a 200-mile access road, two towns, a 191-mile-long railroad from Port Cartier to Lac Jeannine, a hydro-electric generating plant on the Hart Jaune River, and mining, crushing, concentrating and ancillary facilities to support a yearly production of 8.0 million tons of iron ore concentrates at 66% Fe.
In order to meet increasing market demands for iron ore concentrates concurrently with the depletion of its Lac Jeannine reserves, Quebec Cartier announced, late in 1969, the first step toward bringing into production a new iron ore deposit, known as Mount Wright, located 70 air miles northeast of Lac Jeannine and 25 miles southwest of Labrador City, Newfoundland.
In September 1970, the company announced its decision to develop and bring into production its Mount Wright reserves at an annual rate of 18.4 million dry long tons. The scope of this project included the construction of an access road linking the mine, the new town and Labrador City, Newfoundland, the extension of the railroad by some 86 miles, the construction of an ore concentrating plant with all the ancillary facilities, the development of the mine, the construction of a power transmission line and a new town adjacent to Lake Daviault.
The Mount Wright story is divided into five individual papers covering: (a) the history and development of the project; (b) the mine; (c) plant control by a process computer; (d) crushing, grinding and concentrating; and (e) the townsite of Fermont.

Summary: The Mount Wright iron ore mine and upgrading plant were brought on line in the fall of 1975. The mine is located near the Quebec - Labrador border some six hundred miles northeast of Montreal. This paper describes the crushing, grinding and concentrating facilities at Mount Wright, and some design criteria used in equipment selection and flowsheet design. Also mentioned are some "as-built" modifications. A brief description of the over-all flowsheet is also included.

Summary: One of the design criteria for the Mount Wright facilities was to incorporate the latest proven automation techniques and devices for the new crushing, grinding and concentrating plant.
The heart of the centralized control system is a Fox 1 process computer, located in the central control room in the administration building. The entire operation, i.e. crushing, conveying, storing, grinding and concentrating, is monitored and controlled, through the process computer, by one operator via a CRT...

Summary: The Turgeon Lake granite lies 5 miles north of Baie Johan Beetz, Quebec, at the eastern margin of the Grenville Province. The rocks are classed as granites, granulites, quartzites, biotite schists and gneisses, and amphibolites. The granite's uraniferous character is manifested by phosphuranylite, uraninite, and metamict zircons associated with magnetite. Field anomalies occur in irregular pods, conformable with the tectonic foliation, in bands roughly paralleling sedimentary bedding....

Summary: Shovels of 18 cubic yard capacity and larger are described which incorporate advanced technology and techniques providing performance and operation tailored to meet the needs of open-pit mining.
To achieve the goals of increased production at lower cost with consideration of maximum availability, lower energy consumption per ton and low impact on pit power, Harnischfeger Corporation developed a solid-state drive system ("Electrotorque" — P&H trademark) and applied unique transmission...
