Summary: Review of prototype testing of two types of three-phase, argon-stabilized reactor/fun wee indicates specialized advantages for both, as compared with existing metallurgical furnace technology. They are: the direct-arc, plasma-torch furnace (Krupp); and the indirect, plasma extended-arc reactor (PEAR), developed at the University of Toronto.

Summary: Minntac is a taconite mining, concentrating and pelletizing operation located near the town of Mountain Iron, Minnesota, U.S.A. It is totally owned and operated by USX Corporation and represents its largest source of domestic iron units. Minntac began producing fluxed pellets in 1988 and has produced both acid and fluxed pellets since then. This paper compares the acid and fluxed pellets produced at Minntac. It reviews modifications that have been made to the plant flowsheet and discusses...

Summary: Pellet quality has taken on a new dimension during the last ten years. Quality in the seventies was generally defined as adherence to certain physical and chemical specifications. Today, the talk is in terms of how the business is managed, how customer's expectations can be exceeded, not only in product quality, but in service responsiveness.
Coke breeze and flux additions, lower silica levels, and improved furnace control practices have all contributed to the improvement of pellet physical...

Summary: The theory and practice of sampling of paniculate material have been the focus of a continued attention on the part of the mining industry worldwide for almost a century now, because of its critical importance at all phases of a mining project, from exploration (bulk sampling, assaying) to production (grade control) and marketing (quality control). A powerful, complete theory was put together by P. Gy (1968 to 1982), but its applications to gold ores have met with limited success to date, due...
