Sommaire: It is easy to throw darts at government — and government often deserves to be a target. This month, Tax Notes examines tax legislation from a different angle, and sees some bright spots.
The following article is based on a paper presented by the author at the International Gold Symposium in Rio de Janeiro in August 1989.

Sommaire: PT International Nickel Indonesia, a subsidiary of Inco Limited, mines and processes nickel laterite ores for the supply of nickel matte, primarily to the Japanese market. It has large ore reserves and a substantial portion of its energy requirement is supplied from its own hydro-electric plant. Since the early 1980s, the company has increased its production level and has dramatically reduced its unit costs. Projects are in progress to further decrease costs and recently a major expansion...

Sommaire: By 1994, Inco Limited will lower sulphur dioxide emissions from the Copper Cliff smelter by 60% to 265 000 tonnes/year, primarily through implementing two key process changes. First, new milling technology will permit economic rejection of ad-ditonal pyrrhotite prior to smelting. Second, a bulk copper-nickel concentrate will be oxygen flash-smelted, thereby eliminating the existing multi-hearth roasters and reverberato-ry furnaces. All copper will be recovered in the matte separation plant as...

Sommaire: The case is presented for the use of simulators for the computer-based training (CBT) of mining plant operators and for introducing them to automatically controlled systems. As well as their use in the classroom, the role of simulators is examined for "on-plant" use in trouble-shooting, fault-finding and maintenance of automatic systems. Case studies are presented showing how specific simulators are becoming established or have potential in the areas of automated materials handling,...

Sommaire: Inco has shifted part of its traditional extractive research effort at its J. Roy Gordon Research Laboratory in Mississauga toward new, value-added products. Most of the effort is being expended on new Ni powders for batteries and new Ni-coated products which will be produced in Inco's carbonyl nickel refineries. New products under development are Ni-coated powders, Ni-coated fibres and ultra-fine Ni powders. Other new products for advanced material applications include controlled expansion...

Sommaire: In spite of their importance to the economics of many metallurgical projects, the values and technical aspects of precious metals losses in smelting operations are relatively undeveloped subjects. This paper attempts to provide a condensed overview of precious metals losses in pyrometallurgy, using some of the limited production and experimental data available. It is intended for three general groups of metallurgists — operators attempting to improve recoveries, cost-accounting...

Sommaire: Inco Gold Company was created in 1987 as an unincorporated business unit of Inco Limited. In 1988, Inco Gold Management Inc. was incorporated to supply management, exploration and engineering services to this unit. The first new project, at Casa Berardi, Quebec, was brought to production in September 1988, less than two years after completion of exploration. For 1989, Inco Gold's exploration and capital expenditures have been budgeted at approximately $94 million, a record level. Inco Gold...
